Example one

Fig. 1 is a schematic flow chart of an electronic book loading and displaying method according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:

step S101, reading the electronic book to be loaded, determining the target chapter to be loaded, and acquiring the target HTML file corresponding to the target chapter.

The method and the device can be executed on the client side, so that the user can conveniently and directly perform paging rendering on the electronic books to be loaded when reading the electronic books on the client side, the server side does not need to be accessed, and the reading experience of the user is improved.

In this embodiment, the electronic book may be, for example, an epub electronic book, or an electronic book with other formats, and is not limited herein. Reading the electronic book to be loaded from the client, and acquiring the recorded reading identification information of the electronic book to be loaded by the user from the client while reading the electronic book. The reading identification information can record the reading progress of the user, record read chapters, record read text labels, record read page numbers and the like in a percentage mode. And calculating and determining the target chapter to be loaded of the electronic book to be loaded according to the reading identification information. According to different reading identification information, different calculation modes can be adopted, for example, the corresponding read chapters are obtained by calculating the whole electronic book according to the percentage of the reading progress information and are used as target chapters to be loaded; or, directly determining a target chapter to be loaded according to the recorded read chapter; or determining the corresponding target chapter to be loaded according to the record read character label and the record read page number.

And after the target section to be loaded is determined, determining a target HTML file corresponding to the target section for the target section. The target HTML file may be generated by a pre-established HTML file template. And if the target section to be loaded is determined, establishing a corresponding target HTML file for the target section to be loaded, and displaying the target section to be loaded by utilizing the target HTML file.

Further, when the target HTML file is created, the target chapter may include one chapter or may include a plurality of chapters. That is, one target HTML file may contain one chapter or a plurality of chapters. If the target section contains the first section, the target HTML file contains the target section content of the first section; the target chapters comprise a first chapter, a second chapter and a third chapter, and the target HTML file comprises target chapter contents of the first chapter, the second chapter and the third chapter. The implementation can be specifically set according to implementation conditions, and is not limited herein. The electronic book may be composed of a plurality of target HTML files, each target HTML file may include chapter contents of one chapter, and may also include chapter contents of a plurality of chapters, which is not limited herein.

And step S102, extracting the target chapter content corresponding to the target chapter from the target HTML file, and writing the target chapter content into a specified variable of the target HTML file in a character string mode.

After the target chapter is determined, the content of the target chapter corresponding to the target chapter, such as characters, pictures and other elements under the target chapter, needs to be extracted from the electronic book. The extracted target chapter content can be written into a designated variable of a target HTML file corresponding to the target chapter in a character string mode. If the designated variable of the preset set target HTML file is a CHAPTER _ HTML variable, the characters and the pictures (information such as picture loading links and picture storage addresses) are stored by utilizing the CHAPTER _ HTML variable.

Furthermore, different display modes may be available for different electronic books, for example, a display mode from left to right is generally adopted when displaying electronic books in chinese; in general, in an arabic electronic book, a display style from right to left is used for display. When different display styles are configured on different languages of the electronic books of different languages, or different display styles are configured on different electronic books, the style file of the electronic book can be acquired, and the style file is inserted into the head of the target HTML file, so that the display of the target HTML file and the electronic books are guaranteed. The style file comprises a language identifier dir ═ rtl (the language to be displayed from right to left), and the like, and can realize multi-language adaptive display of the electronic book.

Step S103, loading the target HTML file and inserting the specified variable into the target container of the target HTML file.

When the target HTML file is loaded, the target HTML file may be loaded by using a browser kernel, and the browser kernel may be loaded by using, for example, a browser kernel built in the terminal device. While loading the target HTML file, a specified variable needs to be inserted into the target container of the target HTML file, so as to complete the display of the target chapter contents in the target HTML file. When inserting the specified variable into the target container of the target HTML file, the specified variable may be inserted into the target container of the target HTML file, such as a div container, using, for example, a script file, such as a js file, and the target container, such as the div container, may be set in the body of the target HTML file, such as a body tag container, etc.

And step S104, performing paging rendering on the content in the designated variable in the target container by using the browser kernel, and completing paging display of the target chapter content in the electronic book.

In the prior art, when an electronic book is displayed, the electronic book is generally rendered by adopting self development software or a third-party plug-in, on one hand, more cost is needed, on the other hand, the electronic book is not suitable for the existing development trend of the electronic book, and more display problems exist.

In this embodiment, content in a specified variable in the target container may be rendered in a paging manner based on a browser kernel built in the terminal device. And when the page rendering is carried out, the browser kernel carries out page rendering according to the layout attribute information of the target HTML file. The layout attribute information can be recorded by utilizing a css (cs cascading style sheet) file, and the content in the specified variable in the target container can be subjected to page rendering by utilizing a browser kernel according to the layout attribute information in the css file, such as column attribute, so that the target chapter content is subjected to page display.

When the page is displayed, the loading condition of the content in the specified variable in the target container can be monitored, the monitoring comprises monitoring the loading condition of the picture element of the content in the specified variable in the target container, and the client is informed whether the loading and displaying of the target chapter content are completed according to whether the loading of the picture element is completed. The monitoring of the loading condition of the picture element includes, for example, monitoring that the picture element is successfully loaded or unsuccessfully loaded, and at this time, when the loading of the picture element is completed, it may be fed back that the content of the current target chapter has been completed with paging loading, and paging page display is performed.

Optionally, when the electronic book is displayed in a paging mode, the marked information in the electronic book can be acquired. The marked information includes, for example, line drawing information including line drawing information for characters in the contents of a target chapter in the electronic book. When the electronic book is displayed in a paging mode, the marked information can be obtained and marked in the electronic book. During labeling, the elements in the corresponding target chapter content need to be labeled according to the labeled information and the layout attribute information of the target HTML file. If the layout attribute information sets that the characters are displayed from the top to the bottom in a vertical row, the corresponding positions of the characters are marked by drawing lines, such as the marks on the right sides of the characters, and the like. The specific label is set according to the implementation situation, and is not limited herein.

According to the electronic book loading and displaying method provided by the invention, the electronic book to be loaded is read, the target chapter to be loaded is determined, and the target HTML file corresponding to the target chapter is obtained; extracting target chapter content corresponding to the target chapter from the target HTML file, and writing the target chapter content into a specified variable of the target HTML file in a character string mode; loading a target HTML file, and inserting a specified variable into a target container of the target HTML file; and performing paging rendering on the content in the specified variable in the target container by utilizing the browser kernel to complete paging display of the content of the target chapter in the electronic book. The method has the advantages that the target chapter content of the electronic books is written into the designated variable of the target HTML file, the browser kernel is used for loading and page rendering, the accuracy and the normalization of page display of the electronic books can be guaranteed, different electronic books can be compatibly processed, the display effect of the electronic books is improved, the display problem of the prior art when the electronic books are displayed is solved, and the cost consumption is reduced.

Example two

Fig. 2 is a schematic flow chart of an electronic book loading and displaying method according to another embodiment of the present invention, as shown in fig. 2, the method includes the following steps:

step S201, reading the electronic book to be loaded, determining the target chapter to be loaded, and acquiring the target HTML file corresponding to the target chapter.

Step S202, extracting the target chapter content corresponding to the target chapter from the target HTML file, and writing the target chapter content into the designated variable of the target HTML file in a character string form.

Step S203, loading the target HTML file and inserting the specified variable into the target container of the target HTML file.

And step S204, performing paging rendering on the content in the specified variable in the target container by using the browser kernel, and completing paging display of the target chapter content in the electronic book.

The above steps refer to the description of steps S101-S104 in the first embodiment of fig. 1, and are not described again here.

Step S205, receiving a page turning request triggered by a user, and performing page turning processing according to the page turning request.

When a user finishes reading a current page and turns pages backwards or forwards, or the user directly clicks a hyperlink of a certain section from a directory page, or the user directly jumps to a certain page according to a bookmark in an electronic book, and the like, the user can receive a page turning request triggered by the user and needs to perform corresponding page turning processing aiming at the page turning request.

Specifically, it is first determined whether the chapter content corresponding to the page turning is located in the target HTML file according to the page turning request, that is, whether the chapter content corresponding to the page turned is already in the current target HTML file. Here, whether the chapter content corresponding to the page turning is located in the target HTML file is determined according to the target chapter content contained in the current target HTML file and the chapter content corresponding to the page turning request. If the page turning request triggered by the user is a page turning request triggered by the last page of the current target HTML file, the chapter content corresponding to page turning can be determined not to be located in the target HTML file; or, if the target chapter content contained in the current target HTML file is the target chapter content of the second chapter, and the chapter content corresponding to the page turning request is the target chapter content of the third chapter, determining that the chapter content corresponding to the page turning is not located in the target HTML file, and the like.

After the chapter content corresponding to the page turning is judged to be located in the target HTML file, the corresponding page number can be calculated according to the page turning identification information carried by the page turning request, and the page turning process is completed by directly skipping to the page number. The page turning identification information includes, for example, reading progress information, bookmark information, labeling information, chapter anchor information, hyperlink information, page number information, and the like. For the reading progress information, the corresponding page number can be obtained by calculating according to the percentage of the reading progress information; for the bookmark information and the label information, the corresponding page number can be obtained by determining the position corresponding to the character and calculating according to the character contained in the bookmark information or the character contained in the label information, and the corresponding page number can also be determined according to the position of the bookmark information or the position of the label information; for the chapter anchor information, the corresponding page number can be directly determined according to the position of the chapter anchor; for the hyperlink information, the page number of the corresponding chapter of the page turning of the hyperlink information can be determined; for the page number information, the corresponding page number or the like can be directly determined. The above are all illustrations, and particularly, when the page number is calculated according to the page turning identification information, the setting may be performed according to an actual implementation situation, which is not limited herein.

After judging that the chapter content corresponding to the page turning is not located in the target HTML file, determining a target chapter to be loaded corresponding to the chapter content corresponding to the page turning according to the page turning request, executing steps S201-S204, reading the target chapter to be loaded corresponding to the page turning in the electronic book, loading and rendering pages of the target chapter, and completing page display of the chapter content corresponding to the page turning. Meanwhile, after loading and page rendering, corresponding page numbers are calculated according to the page turning identification information for positioning, and page turning is carried out to the page numbers corresponding to the page turning requests.

According to the electronic book loading and displaying method provided by the invention, after a target HTML file is displayed in a paging mode, when a page turning request triggered by a user is received, whether chapter content corresponding to page turning is located in the target HTML file or not is judged according to the page turning request, if yes, a corresponding page number is calculated according to page turning identification information carried by the page turning request, and page turning is finished by skipping to the page number; if not, determining a target chapter to be loaded corresponding to the chapter content corresponding to page turning, processing the target chapter to be loaded, and completing paging display of the chapter content corresponding to page turning so as to respond to a page turning request triggered by a user in time. By judging the page turning request, whether a new target chapter to be loaded needs to be loaded again can be quickly determined, and when the new target chapter to be loaded does not need to be loaded, the page can be quickly turned by directly positioning according to the calculated page number; when a new target chapter to be loaded needs to be loaded, the browser kernel is used for loading and page rendering, so that the page display accuracy and normalization of the electronic book are guaranteed, the chapter content is quickly positioned, and the corresponding page turning request is responded and completed.

EXAMPLE III

Fig. 3 is a flowchart illustrating an electronic book loading and displaying method according to another embodiment of the present invention, as shown in fig. 3, the method includes the following steps:

step S301, reading the electronic book to be loaded, determining the target chapter to be loaded, and acquiring the target HTML file corresponding to the target chapter.

Step S302, extracting the target chapter content corresponding to the target chapter from the target HTML file, and writing the target chapter content into the designated variable of the target HTML file in a character string form.

Step S303 loads the target HTML file, and inserts the specified variable into the target container of the target HTML file.

And step S304, performing paging rendering on the content in the designated variable in the target container by using the browser kernel, and completing paging display of the target chapter content in the electronic book.

Step S305, when the layout attribute information of the target HTML file is monitored to be changed, the reloaded target HTML file is subjected to re-paging processing.

When a user adjusts the layout attribute information of the electronic book, such as adjusting the font display size, the font style, the paragraph display style, the layout format, and the like, the target HTML file after page rendering needs to be re-paged when reloading.

When it is monitored that the layout attribute information of the target HTML file is changed, for the reloaded target HTML file, the page number of the target HTML file before reloading needs to be determined according to the reading progress information of the target HTML file, and the first element of the page corresponding to the page number of the target chapter content is obtained. The elements include text, pictures, etc. The first element of the page number may be a picture or a text, and the text is generally the first text of the page corresponding to the page number (if the target HTML document is displayed from left to right, the first text in the upper left corner).

After determining the first element, the position data of the first element is further determined. The position data is position data of the element in the lateral coordinates of the first coordinate system. The first coordinate system is established by taking the first element position of a first page of a target HTML file displayed by the terminal as an origin. If the leftmost character of the first page of the target HTML file is the origin (according to the first character in the first character node in the target HTML file being the origin, the character node is the node whose content in the container in the target HTML file is the character, i.e., < div > XXXX < div > is the character node), the horizontal coordinate axis is the coordinate axis consistent with the page turning direction of the electronic book, and if the page turning direction is the page turning to the right, the horizontal coordinate axis is the coordinate axis in the left-right direction. The position data of the first element is determined from the lateral coordinates of the first element on the lateral coordinate axes of the first coordinate system. And for the picture with the first element, acquiring the position data of the picture, wherein the position data of the picture can pass through a target HTML file, and acquiring the position data of the picture in the HTML file according to the attribute information of the HTML file. Alternatively, the position data may also be acquired as described above. For the first element being a text, the position data of the text can be obtained in the above manner. Here, the electronic book is displayed in a target HTML file manner, so that the position data of the first element can be conveniently acquired, and the subsequent re-paging processing according to the position data of the first element is also facilitated.

And according to the position data and the layout attribute information of the first element, performing paging rendering again, and determining the page number of the reloaded first element. Specifically, according to the position data x of the first element, the layout attribute information includes, for example, the width y of the displayable element corresponding to the terminal screen, and it is determined that the page number after reloading the first element is rounded up (x/y), so as to obtain the page number after reloading the first element, and complete the re-paging processing of the target HTML file.

According to the electronic book loading and displaying method provided by the invention, when the change of the layout attribute information of the target HTML file is monitored, the re-paging processing is carried out on the newly loaded target HTML file according to the attribute of the target HTML file. The electronic book is displayed by adopting the target HTML file, so that the position data of the first element can be conveniently obtained, the subsequent re-paging processing according to the position data of the first element is also facilitated, and the target HTML file can be quickly and accurately re-paged during re-loading.

Example four

Fig. 4 is a flowchart illustrating an electronic book loading and displaying method according to another embodiment of the present invention, as shown in fig. 4, the method includes the following steps:

step S401, reading the electronic book to be loaded, determining a target chapter to be loaded, and acquiring a target HTML file corresponding to the target chapter.

Step S402, extracting the target chapter content corresponding to the target chapter from the target HTML file, and writing the target chapter content into the designated variable of the target HTML file in a character string manner.

Step S403, load the target HTML file, and insert the specified variable into the target container of the target HTML file.

And S404, performing paging rendering on the content in the designated variable in the target container by using the browser kernel, and completing paging display of the target chapter content in the electronic book.

In step S405, a plurality of chapter anchors included in the target HTML file are sequentially acquired.

For the problem that a target HTML file contains a plurality of chapter anchors and the chapter anchors are nested, the prior art cannot accurately position the nested chapter anchors and determine the corresponding chapter anchors.

In this embodiment, the method and the device can be applied to a scenario where, when a user reads an electronic book, a corresponding chapter read by the user needs to be marked in a directory. When the target HTML file contains the target chapter contents of a plurality of chapters, the target HTML file contains a plurality of chapter anchors, which results in that the chapter currently read by the user cannot be determined. Therefore, determination of position data for a plurality of chapter anchors is required to determine whether or not chapter contents are within the display range of the terminal screen. Here, it is assumed that the chapter contents that have been read are not in the display range of the terminal screen, and that the chapter contents that are being read or the chapter contents that are located after the chapter contents that are being read are in the display range of the terminal screen.

For a plurality of chapter anchors, a plurality of chapter anchors contained in the target HTML file are sequentially acquired according to the sequence of the chapter anchors. Each chapter anchor has a unique anchor id, and the anchor ids can be stored in a preset array in sequence.

In step S406, anchor point position data of a plurality of chapter anchors is calculated.

For a plurality of chapter anchors, anchor point position data of each chapter anchor is calculated. The anchor point position data is recorded in a second coordinate system. The second coordinate system is established by taking the first element position of the page displayed by the terminal as an origin (for example, the first character of the page displayed by the current terminal is taken as the origin), and the transverse coordinate axis is the coordinate axis consistent with the page turning direction of the electronic book. As shown in fig. 5, a horizontal coordinate axis consistent with the page turning direction of the electronic book is established with the first element of the page displayed by the terminal as the origin.

The anchor point position data is the sum of the position data of the first element of the chapter content to which the chapter anchor belongs and the total width data of all elements of the chapter content to which the chapter anchor belongs. The position data of the first element is position data of the first element in the lateral coordinate of the second coordinate system. As shown in fig. 5, the position data of the first element is located to the left of the origin, and its value is assumed to be-300. And the total width data is coordinate length data occupied by all elements of the chapter contents belonging to the chapter anchor points in the transverse coordinates of the second coordinate system. If all elements in the chapter contents occupy two pages in the horizontal coordinate axis of the second coordinate system as shown in fig. 5, the total width data is 600 from-300 coordinates to 300 coordinates. And calculating anchor point position data of-300 +600 of 300. Here, the anchor position data may indicate whether chapter contents of a chapter to which the chapter anchor belongs are within a display range of the terminal screen. As shown in fig. 5, the anchor point position data of the chapter anchor in the figure is 300, which is greater than 0, and as shown in fig. 5, part of the content of the chapter to which the chapter anchor belongs is located on the page displayed by the terminal, that is, the chapter content of the chapter to which the chapter anchor belongs is located in the display range of the terminal screen. And calculating the position data of the anchor points of the plurality of chapter anchors according to the mode. When the anchor position data is greater than or equal to 0, the chapter content of the chapter to which the chapter anchor belongs is indicated to be within the display range of the terminal screen, and when the anchor position data is less than 0, namely, when the anchor position data is a negative value, the chapter content of the chapter to which the chapter anchor belongs is considered not to be within the display range of the terminal screen.

Step S407, performing reverse traversal on the anchor position data of the plurality of chapter anchors according to the chapter anchor sequence until determining the first chapter anchor whose anchor position data is a negative value.

And performing reverse-order traversal on the anchor point position data of the plurality of chapter anchor points according to the chapter anchor point sequence, namely sequentially traversing from the last chapter anchor point forward, judging whether the value of the anchor point position data of each chapter is a negative value, namely judging whether the chapter content of the chapter to which each chapter anchor point belongs is not in the display range of the terminal screen, and finding the first chapter anchor point of which the anchor point position data is a negative value, namely finding the chapter anchor point of which the first chapter content is not in the display range of the terminal screen.

Step S408, judging whether the position data of the first element of the content of the chapter of the next chapter anchor of the chapter anchor is a negative value.

After the first chapter anchor point with the anchor point position data being a negative value is determined, if the first chapter anchor point with the anchor point position data being a negative value is the chapter anchor point of chapter 4, that is, the chapter content of chapter 4 is not in the display range of the terminal screen, the chapter content of chapter 5 is in the display range of the terminal screen, it is further necessary to determine whether the position data of the first element of the chapter content of the chapter anchor point of the next chapter of the chapter anchor point is a negative value. That is, the position data of the first element of the chapter anchor of chapter 5 is determined, whether the lateral coordinate of the first element of the chapter anchor of chapter 5 in the second coordinate system is a negative value is determined, when the lateral coordinate of the first element of the chapter anchor of chapter 5 in the second coordinate system is determined to be a negative value, it is determined that the first element of chapter 5 is not in the page displayed by the terminal, but the chapter 5 is in the display range of the terminal screen, which indicates that the user is currently reading chapter 5, it is determined that chapter 5 is the target chapter, and step S409 is executed. When it is determined that the lateral coordinate of the first element of the chapter anchor point of chapter 5 in the second coordinate system is not a negative value, it indicates that some elements in the chapter content of chapter 4 still remain in the page displayed by the terminal, i.e., the chapter 4 is currently being read by the user, and then the chapter 4 is determined to be the target chapter, and step S410 is executed.

Step S409, the chapter where the next chapter anchor is located is taken as the target chapter.

And if the position data of the first element of the content of the chapter to which the anchor point of the next chapter of the anchor point of the chapter is judged to be a negative value, taking the chapter to which the anchor point of the next chapter as the target chapter.

In step S410, the chapter where the chapter anchor is located is taken as the target chapter.

And if the position data of the first element of the content of the chapter of the next chapter anchor of the chapter anchor is judged not to be a negative value, taking the chapter of the chapter anchor as a target chapter.

In step S411, the target chapter is marked.

The marking process for the target chapter includes, for example, marking a red font, setting it to a reading state, and the like.

Further, in this embodiment, if the anchor position data of the plurality of chapter anchors are traversed in the reverse order according to the chapter anchor sequence and no negative chapter anchor is found, the chapter where the first chapter anchor is located is taken as the target chapter, and the marking processing is performed, that is, all chapters are located in the display range of the terminal screen, and reading is started from the first chapter.

In this embodiment, the method can be applied to a scenario where, when a user is reading an electronic book, a corresponding chapter read by the user needs to be marked in a directory. When the chapter currently read by the user is judged to be chapter 4, that is, the target chapter is chapter 4, the information of chapter 4 in the directory is marked as the reading state.

According to the electronic book loading and displaying method provided by the invention, the problem that a plurality of chapter anchors are nested in a target HTML file can be effectively solved, and the chapter content where the chapter anchors are located is determined to be in the display range of a terminal screen by calculating the anchor position data of the chapter anchors. And performing reverse-order traversal on the anchor position data of the plurality of chapter anchors according to the chapter anchor sequence, determining the first chapter anchor which is not in the display range of the terminal screen, and judging the next chapter anchor of the chapter anchor so as to accurately obtain the target chapter anchor and finish marking the target chapter anchor.
