Detailed Description
The following description of the technical solutions according to the embodiments of the present invention will be given with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The embodiment of the invention provides a method and a device for displaying form information in a PDF document and electronic equipment.
In the embodiment of the invention, the electronic equipment can be any electronic equipment such as a computer, a mobile phone and a tablet personal computer which can process PDF format files.
Referring to fig. 1, fig. 1 is a flowchart of a method for displaying form information in a PDF document according to an embodiment of the present invention, including the following steps:
step 101, acquiring all form filling items in a PDF document which is edited currently; the form filling item includes: form filling items that have been filled in by the user and unfilled form filling items in the PDF document.
Specifically, the step of obtaining all form filling items in the currently edited PDF document may include:
traversing objects in the PDF document in sequence;
if the traversed object is a form filling item, recording the traversed object;
if the traversed object is not a form fill-in, a step of sequentially traversing the objects in the PDF document is returned.
Here, according to the definition of the PDF standard protocol, elements in the PDF document are called objects, one form filling item is also an object, and the types of the objects are distinguished by the names of the objects, so that all form filling items in the document can be found out by traversing the objects in the document in turn.
Step 102, the form filling item which is filled in by the user and the form filling item which is not filled in by the user in the PDF document are displayed in a distinguishing mode on the current display page.
In one implementation, there are many ways to distinguish between displays, for example: form filling items can be displayed in different colors, white representing filled in and red representing unfilled out; the filled-in form filling-in items and the unfilled-out form filling-in items may also be displayed in different item bars, respectively. The embodiments of the present invention can be implemented as long as a method can distinguish between a filled-in form filling item and a non-filled-in form filling item.
The form information display method of the PDF document provided by the embodiment of the invention can be used for displaying the filled form filling items and the unfilled form filling items in the PDF document in a distinguishing way, and when a user edits the form information in the PDF document, the form filling conditions in the PDF document can be conveniently obtained, and the occurrence of misplugging or missing filling is prevented.
Referring to fig. 2a, fig. 2a is another flowchart of a form information display method in a PDF document according to an embodiment of the present invention, including the following steps:
step 201, a fill list button is displayed in a menu bar.
In one implementation, the fill list button is displayed in a menu bar of software such as a PDF reader or PDF editor that can view or edit a PDF file. In this embodiment, a fill-in list button may be added in advance to a menu bar of software that can view or edit the PDF file, and when the software is opened, the fill-in list button is displayed.
Step 202, it is detected whether the fill list button displayed on the current page is clicked by the user.
In one implementation, the user's click operation may be a mouse click or a touch click.
And 203, after detecting that the filling list button is clicked by a user, acquiring all form filling items in the currently edited PDF document.
In one implementation, all form fill-in items in the acquired PDF document include form fill-in items that the user has filled in and form fill-in items that the user has not filled in.
In one implementation, form fill-in items in a PDF document are objects in the PDF document that have various properties, such as: size, location, type and filling status in the document, etc., when the program traverses all objects in the PDF document, all form filling items and attribute information in the document can be found.
Alternatively, closing the fill list button may be clicking on the fill list button again after the button has been clicked, or clicking on any other location in the document, or clicking on any blank location in the document.
Step 204, configuring the data in the list of the form item according to all the form filling items in the acquired PDF document which is currently edited.
In one implementation, all form fill-in items and some attribute information in the PDF document are required when configuring the list of form items.
Step 205, a list of list items of the list item is displayed on the current display page.
In one implementation, the list of form listings is displayed differently for filled-in form fill-in items and unfilled form fill-in items in the PDF document, such as by typing in a checkbox corresponding to the filled-in form item.
Specifically, referring to fig. 2b, fig. 2b is an embodiment of displaying a list of list items in the PDF document in the embodiment shown in fig. 2 a;
as shown in fig. 2b, there is a "fill list" button in the form column of the menu column, and after the button is clicked, the form fill item and some attribute information in the PDF document are displayed, for example, the attribute information shown in fig. 2b is: whether the form is filled in by a user or not is expressed as whether a square frame displayed in parallel with the form filling item is marked; input prompts for each form fill-in item, for example: displaying input characters in parallel in the address form filling item, wherein the input characters are required to be input in the address form filling item; displaying an option in parallel in whether to determine the form filling item, wherein the option is required to be selected in whether to determine the form filling item; the number and filling situation of all the form filling items in the PDF document are represented by 10 positions displayed at the top of all the form filling items, 2 positions are filled, which means that 10 form filling items in the current PDF document are filled in, 2 are filled in, 8 are not filled in, a scroll bar is arranged on the right side of a filling list in fig. 2b, 10 form filling items are actually arranged in the figure, and when the scroll bar is scrolled downwards, two other form filling items which are not displayed in the current picture can be displayed.
Therefore, by applying the form information display method provided by the embodiment of the invention, the filling list button can be displayed in the menu bar, and the attribute information of the form filling item in the PDF document is displayed after the button is clicked, so that the user is helped to know the filling condition of the form filling item in the document integrally, and the user can edit the form in the PDF document more conveniently.
Specifically, the step of displaying the form filling item which is already filled in by the user and the form filling item which is not filled in by the user in the PDF document in a distinguishing manner on the current display page may include:
configuring data in a list of the form items according to the form filling items which are filled in by the user and the form filling items which are not filled in the PDF document; list of list items comprising: status flag information for each form filling item, and whether each form filling item has been filled in by the user;
a list of list items of the list item is displayed on the current display page.
In one implementation, the list of form list is always present in software for viewing or editing PDF files, the content in the list of form list is empty before the form filling item in the currently edited PDF file is acquired, and the data in the list of form list is configured according to each form filling item and some attribute information after the form filling item in the currently edited PDF file is acquired.
Therefore, by applying the embodiment of the invention, the list of the form filling items can be configured according to the form filling items filled in by the user and the unfilled form filling items in the PDF document, and the list of the configured form list can be displayed, so that the user can conveniently see the filled form filling items and unfilled form filling items in the PDF document which are edited currently.
Specifically, the flag information of whether each form filling item has been filled in by the user may be: a checkbox displayed in parallel with each form filling item; the checkbox is checked to identify that the form filling item has been filled in by the user, and the checkbox is not checked to identify that the form filling item has not been filled in by the user.
In one implementation, when a user has completed filling a form filling item, the filling state of the form filling item may be obtained, and the program automatically generates a hook in a hook frame corresponding to the form filling item in the list of form items.
Therefore, by applying the embodiment of the invention, the opposite hooks can be displayed in the parallel hook boxes of the filled form filling items so as to be different from the unfilled form filling items, thus the user can more conveniently distinguish the filled form filling items from the unfilled form filling items.
Specifically, the list of list items may further include: an input prompt for each form fill-in item; and/or the statistical information of the quantity of form filling items in the PDF document.
In one implementation, how many items each of the filled-in form and unfilled form are in the currently edited PDF document may be displayed at the top of the list of form items.
In one implementation, the input prompt for the form fill-in item may also be what the user has entered; for example: when the user moves the mouse to a certain form item in the list of form items, the content filled in by the user in the form item is displayed.
Therefore, by applying the embodiment of the invention, the input prompt and the quantity statistical information can be displayed in the list of the list items, so that a user can more conveniently know the filling condition of the list items in the currently edited PDF document when using the PDF document.
Further, referring to fig. 3, fig. 3 is a flowchart of a form filling item state modification method in a form information display method in a PDF document according to an embodiment of the present invention, including the following steps:
step 301, detecting whether a form filling item not filled by a user in a form information list is currently filled by the user, and whether the content of the form filling item which has been filled by the user is deleted by the user.
In one implementation, when a user edits a form filling item in a PDF document, a program updates a filling state of the form filling item in a form information list in real time, including whether the filled item becomes unfilled, and whether the unfilled item becomes filled.
Optionally, when the user updates the status of the form filling item, the status of the list of form items may be a display or a closed status; for example: when the user edits the form filling item, the list of the form item is automatically closed, the filling state of each form filling item in the list of the form item is updated according to the updating condition of the form filling item in the PDF document by the user, and when the user clicks the filling list button again, the updated list of the form item is displayed.
Step 302, the state marking information of the form filling item filled in by the user is modified to be filled in by the user.
In one implementation, after a user fills in content in an unfilled form fill-in item, the status marking information of the form fill-in item is marked as filled-in.
Step 303, the state marking information of the form filling item of which the content is deleted by the user is modified to be not filled by the user.
In one implementation, after deleting content in a filled form, a user marks the status marking information of the form as unfilled.
Therefore, by applying the form information display method provided by the embodiment of the invention, the filling state of the form filling item in the form list of the PDF document can be updated according to the filling state of the form filling item in the PDF document and displayed, so that a user can more accurately obtain the filling condition of the form filling item in the PDF document when editing the PDF document.
Referring to fig. 4, fig. 4 is a flowchart of a page switching method in a form information display method in a PDF document according to an embodiment of the present invention, including the following steps:
step 401, obtaining a target form filling item; the target form filling item is: form filling items in the form information list clicked by the user.
In one implementation, after the user clicks the fill list button, a list of form information lists is displayed, and the user may click on a form fill item in the list of form information lists. For example: click on the address form fill-in item in fig. 2 b.
Step 402, obtaining a target position; the target positions are: the location of the target form fill-in item in the PDF document.
In one implementation, as can be seen from the description in fig. 2, when the form filling item is traversed, attribute information of the form filling item is obtained, where the attribute information includes a position where the form filling item exists in the PDF document.
Step 403, switching the currently displayed page to the target position.
In one implementation, there are many ways of switching, for example: the current page can be jumped to the page where the target form filling item is located, and the current page can be rolled to the page where the target form filling item is located.
Specifically, the step of switching the currently displayed page to the target position may include:
switching the current page to the page where the target form filling item is located according to a preset switching mode; after the switching, the position of the target form filling item in the display document comprises: centered, uppermost or lowermost.
Optionally, after the page is switched, the target form filling item may also be highlighted, for example: after highlighting for 1 second with a color different from the content and the current background color on the background of the target form filling item, the background color is restored to the one before switching.
Optionally, when the page is switched, the state of the list of the list items can be displayed or the program is automatically closed; for example: after the user clicks the form filling item in the form information list, closing the form information list and switching the current page to the page where the form filling item is located.
Therefore, by applying the form information display method provided by the embodiment of the invention, the current page can be switched to the form filling item according to the form filling item clicked by the user in the form information list, so that the user can find the form filling item which is missed when the user finds the form filling item which is missed in the form information list, and the use is convenient.
