Specific embodiment
In order to make the above objects, features, and advantages of the present application more apparent, with reference to the accompanying drawing and it is specific real
Applying mode, the present application will be further described in detail.
Referring to Fig. 2, a kind of stream of an embodiment of the method using Lifetime of Web Pages optimization application of the application is shown
Journey schematic diagram.The described method includes:
Step 201, the frame object of current web page is obtained according to the current event of browser control part object.
When browser control part window includes the main page sub-pages nested with one or more, the main page is known as leading
Frame, the sub-pages are known as subframe.Wherein, prime frame, subframe respectively correspond different WebBrowser objects.Those skilled in the art
Member is readily appreciated that browser control part WebBrowser is interacted by event and outside, for example, when user is in browser address
When inputting URL carriage return progress browse operation in column, WebBrowser control will trigger BeforeNavigate event.From event
The WebBrowser object for triggering the event, i.e. frame object can be obtained in the parameter transmitted.
When in browsing device net page including prime frame and one or more subframes, BeforeNavigate event is triggered
It can be prime frame, it is also possible to be wherein any one subframe, therefore may be main based on frame object acquired in event argument
The frame object of the frame object of frame or any one subframe.
Step 202, the state machine object of the frame object is obtained.
Specifically: before the state machine object of creation frame object, according to preset state machine mapping table, described in judgement
The state machine object of frame object whether there is；If it does not exist, then the state machine object of current frame object is created, and is reflected in state machine
The mapping relations of current frame object and corresponding states machine object are stored in firing table；If it exists, it according to the state machine mapping table, obtains
Take the state machine object of the frame object.
For the life cycle of a webpage, after user inputs URL and presses enter key, navigation can be triggered first
Preceding event BeforeNavigate event, therefore the starting/entry events of the event i.e. Lifetime of Web Pages.Later, with
The operation of user will continue to trigger other events, the NavigateComplete2 event triggered when such as navigation is completed, under
Carry the DownloadBegin event etc. triggered when starting.
Method provided herein can both use in the entry events BeforeNavigate of Lifetime of Web Pages,
Also response processing is done to other events in combination with specific implementation situation, we are not particularly limited to this, can be by art technology
Personnel are voluntarily handled according to practical situations when implementing the application.
Step 203, it is based on the state machine object, records the life cycle information of current web page.
The life cycle mark of webpage is illustrated below for recording state change of the webpage in whole life cycle
It is bright:
Unkown: original state
Newborn: raw when both BeforeNavigate event is triggered for the first time when the life cycle of webpage just starts
Life period indication is set to newborn.
Adult: when webpage, which loads, to be completed, i.e., life cycle mark is set after NavigateComplete2 event is triggered
For adult.
Dead: Lifetime of Web Pages terminates, i.e., when BeforeNavigate event is again triggered, life cycle is identified
It is set to dead, has new URL to be input by a user at this time, Lifetime of Web Pages terminates before, while the life cycle of new web page
Start.
The above life cycle mark example is merely for convenience of understanding present context, and those skilled in the art are easy reason
Solution, when implementing the application, can according to the needs of practical application, be arranged the pilot process status indicator of Lifetime of Web Pages, and
And the life cycle mark can be changed in different event inlet.Moreover, other than above-mentioned life cycle mark,
Other status indicator can also be added in state machine object, to realize different application operatings, such as: remember for download event
The download state of each download thread is recorded, and more newly downloaded in DownloadBegin and DownloadComplete event
The status indicator of thread.
Step 204, each application obtains the life cycle information of corresponding web page according to self-demand；And based on acquired
Life cycle information executes corresponding optimization operation.
Life cycle information in state machine of the applications by obtaining frame object is it can be learnt that the current net of the frame object
The situation of change of page life cycle, and make a response processing.For example, the life cycle information that applications pass through state machine object
Have learned that corresponding Lifetime of Web Pages has terminated, then resource related with the webpage in applications can be discharged,
Such as in the application to handle the related dedicated program of display effect of network page, memory space etc., if learning the Lifetime of Web Pages
Terminate, so that it may discharge the occupied system resource of these programs, memory space etc. in time.
Referring to embodiment one and Fig. 3, Fig. 3 shows a kind of embodiment two of Lifetime of Web Pages control method of the application
Flow diagram.Opposite embodiment one, embodiment two have still further comprised the description to state machine is destroyed, the webpage life
Cycle control methods specifically include:
Step 301, the frame object of current web page is obtained according to the current event of browser control part object.
Step 302, according to preset state machine mapping table, judge that the state machine object of the frame object whether there is；If
It is not present, creates the state machine object of the frame object, the frame object and corresponding shape are stored in the state machine mapping table
The mapping relations of state machine object；If it exists, step 303 is executed.
The mapping relations being stored in preset state machine mapping table between frame object and corresponding states machine object, to remember
Whether record is that the frame object creates state machine object.The following are the examples of a state machine mapping table, wherein deposits in mapping table
The value for storing up frame object pointer key and state machine object constitutes a key-value pair:
In the application, the state machine mapping table can be come from outside application program, such as database, external file；
In addition, the state machine mapping table can also be placed in inside program, in the same DLL, application program.
Preferably, preset condition machine control object, the state machine mapping table are placed in the state machine control object.Institute
State state control pair as be located at global space in, i.e., in entire application program or DLL any method or event can all lead to
It crosses the state machine control object and searches the state machine mapping table.
Preferably, frame object and corresponding state machine object are stored in the state machine mapping table by binary tree structure
In.The mapping relations of frame object and state machine object can be stored according to plurality of data structures such as arrays.But we are with two
Fork storage of data structure frame object and state machine object are remarkably improved search efficiency when searching according to binary tree structure, reduce
Search spent time and system resource.
Step 303, according to the state machine mapping table, the state machine object of the frame object is obtained.
Step 304, it is based on the state machine object, records the life cycle information of current web page.
Step 305, if current event is the Life Cycle in the preceding event BeforeNagvate of navigation and state machine object
Phase information is active state, then destroys the current state machine object of frame object, then creates new state machine object, and by frame pair
As the mapping relations storage with newly created state machine object or update into state machine mapping table.
For the state machine object of the same frame object, the triggering when the web page windows in frame object are navigated for the first time
When BeforeNavigate event, the life cycle information in corresponding state machine object is marked as active state, at this
The state is newborn in example, and later as other events are triggered, the life cycle state mark may be marked as it
His active state, such as adult.Therefore, if current BeforeNavigate event is again triggered, while life cycle state mark
Knowing is not unkown, but the life state of a centre, then illustrates that current frame object is to trigger for the second time
BeforeNavigate event has new URL to be navigated at this time, also implies that the Lifetime of Web Pages knot before the frame object
Beam.
It is found from preset state machine mapping table according to current frame object first and destroys the current state machine of frame object
Object；Then new state machine object is created for frame object, and by the storage of the mapping relations of frame object and state machine object or more
Newly into state machine mapping table.It stores, is also possible to according to frame pair again after original mapping relations can be deleted when update
As finding and updating original mapping relations.
Step 306, further, by judging that current frame object is prime frame or subframe, to execute corresponding destruction respectively
State machine object operation.
In this application, prime frame object and current can be all passed to when the method that we call state machine object implements operation
Frame object: if present frame pointer to object is identical as prime frame pointer to object, current frame object is main frame；If it is different, then present frame
Object is subframe.
If current frame object is main frame, the state machine object of the prime frame is destroyed；Ergodic state machine mapping table is obtained and is destroyed
The state machine object of the corresponding whole subframes of the prime frame；Then, prime frame and corresponding all is deleted from state machine mapping table
The mapping relations of subframe and respective state machine object.When prime frame is destroyed, the release of current global space can be triggered, it also can trigger bit
The destructed method Free up Memory of state machine management class in global space, by method triggering release institute destructed in state machine management class
There is subframe state machine object.
If current frame object is subframe, corresponding state machine object is found according to the subframe and state machine mapping table and is then sold
It ruins, while deleting corresponding mapping relations in state machine mapping table.It, can triggering state machine object when subframe state machine object is destroyed
Destructed method, discharge corresponding memory source.
The step is optional step.Before the life cycle of webpage is not finished, applications can pass through corresponding state machine
Life cycle information in object obtains the life cycle of current web page.
Preferably, the processing related with Lifetime of Web Pages that the application is done applications writes on state machine object
In interface, in this way, the applications can know immediately corresponding state machine object by interface when state machine object is destroyed
It is whether destroyed, illustrate that the Lifetime of Web Pages of the state machine object has terminated if destroying.
It is retouched above by a kind of method using Lifetime of Web Pages optimization application of several embodiments to the application
