Script execution between process provided by the invention refers to the script execution between page process and detached process. Wherein page process runs the process of Web page, and detached process is another process independent of page process. When the page has ActiveX plug-in unit, page process is run ActiveX plug-in unit and is acted on behalf of object, and detached process runs ActiveX plug-in unit moving object, and this ActiveX plug-in unit moving object is the object of real ActiveX plug-in unit. In the examples below, for ActiveX plug-in unit as Flash plug-in unit is described, but the present invention is not limited only to this.
Before the script execution introduced between page process and detached process, first introduce Flash plug-in unit and act on behalf of object and the establishment process of Flash plug-in unit moving object. Fig. 1 shows the schematic diagram that the establishment process of object and Flash plug-in unit moving object acted on behalf of by Flash plug-in unit in the present invention. As shown in Figure 1, running and have Web page and Flash plug-in unit to act on behalf of object in page process, running in detached process is the free page and Flash plug-in unit moving object.
Wherein, run the agency of the Flash in page process to the process liking the page process creation Flash moving object by tackling browser, replace the actual Flash moving object to be created and create. Specifically, the page has Flash, when browser creates Flash plug-in unit, can according to Flash plug-in unit CLSID (class mark, obtain by CLSIDFromProID) or ProgID (the character string identification symbol of assembly) inquiry registration table, checking whether system has installed this Flash plug-in unit, if installing, continuing establishment process. When page process continues to create Flash plug-in unit, interception CoGetClassObject, creates Flash plug-in unit and acts on behalf of object, and this Flash plug-in unit is acted on behalf of object and comprised a series of interface, comprise a lot of standard interfaces that IUnknown pointer will call, such as IOleObject, IViewObject etc. Then, when calling the CreateInstance of IClassFactory, the Flash plug-in unit created is acted on behalf of the IUnknown pointer that object returns to page process. Thus Flash plug-in unit is acted on behalf of Object Creation and is completed.
The Flash plug-in unit moving object run in detached process is when object acted on behalf of by page process activation Flash plug-in unit, creates in the detached process independent of page process. Specifically, page process activate Flash plug-in unit act on behalf of object time, extract the relevant informations such as the attribute of this Flash plug-in unit, URL, size, then create a detached process. First, create a file (document), i.e. the empty page, insert an object (object) wherein, this detached process calls CoGetClassObject, tackles this CoGetClassObject, creates a Flash plug-in unit moving object. This Flash plug-in unit moving object comprises a series of interfaces, comprises a lot of standard interfaces that IUnknown pointer will call, such as IOleObject, IViewObject etc. Then, when calling the CreateInstance of IClassFactory, the Flash plug-in unit moving object created is returned to the IUnknown pointer of detached process. Thus Flash plug-in unit moving object has created.
Then, in Flash plug-in unit acts on behalf of object and Flash plug-in unit moving object, create the communication window associated with plug-in object respectively, act on behalf of object for making Flash plug-in unit and communicate with Flash plug-in unit moving object. By these two communication windows, two objects can carry out for the size of Flash, focus, refreshing, script and out of Memory alternately.
Further, if there being nesting structure in Web page, namely page process is run multiple father's page and multiple subpage face. Whenever page process creation page and when acting on behalf of object, the object ID (also can comprise its URL) that acts on behalf of of the father's page acting on behalf of object ID (also can comprise its URL) and this subpage face in subpage face is sent to detached process, according to the hierarchical structure activity of constructing object of correspondence in detached process. In this case, the object of acting on behalf of run in page process is multiple, it is multiple for running the moving object in detached process, act on behalf of object and moving object one_to_one corresponding, each communication window acting on behalf of object and the communication window acting on behalf of moving object corresponding to object with this have corresponding attribute, are realized moving object and the communication of acting on behalf of object corresponding with it by these two communication windows.
Fig. 2 shows the schema of script execution 200 between process according to an embodiment of the invention. The method is applicable to act on behalf of, by the Flash plug-in unit run in page process, the script that object performs the Flash plug-in unit moving object running in detached process, and namely the method is the method for the page in the Flash plug-in unit moving object control page process running in detached process. As shown in Figure 2, method 200 starts from step S201, and wherein script is sent to Flash plug-in unit by communication window and acts on behalf of object by Flash plug-in unit moving object. The button created is clicked on Flash with user, triggering page blackening is example, when clicking the button on Flash as user, Flash plug-in unit moving object obtains script corresponding to button click operation, by communication window, this script is sent to Flash plug-in unit and acts on behalf of object.
Subsequently, method 200 enters step S202, and wherein Flash plug-in unit is acted on behalf of in object query page process and performed relevant interface with script, obtains script execution according to this interface. After the script that object receives above-mentioned button click operation correspondence acted on behalf of by Flash plug-in unit, inquiry and the IHTMLWindow interface obtained in page process, IHTMLWindow interface is perform relevant interface with script, ExecScript in this IHTMLWindow interface is the function for performing script, and namely ExecScript function provides script execution.
Subsequently, method 200 enters step S203, and wherein Flash plug-in unit is acted on behalf of object and performed this script according to script execution. Flash plug-in unit is acted on behalf of object and is performed script corresponding to above-mentioned button click operation according to the script execution that ExecScript function provides, and makes page blackening.
According to the script execution between the process that the present embodiment provides, after script is sent to and to act on behalf of object by moving object, act on behalf of in object query page process and perform relevant interface with script, the method of script execution is obtained according to this interface, and then according to the script that sends over of method executed activity object that script performs, thus achieve the execution of script between different process, and achieve the moving object running in detached process to the control of the page run in page process. Further, in the method, object is acted on behalf of by running in page process, and in detached process, running moving object so that real ActiveX plug-in unit is separated with page process, thus can not affect the page process when ActiveX plug-in unit is gone wrong, improve the stability of browser, when the safety issues such as virus especially occur when ActiveX plug-in unit, also page process can not be had an impact, it is to increase the security of browser; Meanwhile, page process goes wrong can not affect the normal operation of ActiveX plug-in unit, it is to increase the stability of plug-in unit.

After detached process has created Flash plug-in unit moving object, the variable of Flash plug-in unit moving object can be notified to the page, page developer writes the script obtaining Flash version number according to this variable in the page, and method pending in this script obtains Flash version number exactly. Flash plug-in unit is acted on behalf of object, by communication window, the script obtaining Flash version number is sent to Flash plug-in unit moving object.
Subsequently, method 300 enters step S302, wherein Flash plug-in unit acts on behalf of object by calling the dispatch interface of Flash plug-in unit moving object, allow Flash plug-in unit moving object perform the method obtaining the scheduling identification of pending method in script, after Flash plug-in unit moving object obtains this scheduling identification, by communication window, scheduling identification is returned to Flash plug-in unit act on behalf of object. Specifically, first page parsing script, the title of method pending in this script is transferred in the IDispatch interface that object acted on behalf of by Flash plug-in unit, IDispatch interface is dispatch interface, for the function called in the language program not supporting empty function table, IDispatch interface has GetIDsOfNames function and Invoke function, the title that wherein GetIDsOfNames function provides Application way returns the method for its dispatch id, and Invoke function provides the instruction of the dispatch id manner of execution of Application way. Owing to the scheduling identification (ID) that object cannot know pending method in script acted on behalf of by Flash plug-in unit, so the IDispatch interface that object calls Flash plug-in unit moving object by communication window acted on behalf of by Flash plug-in unit. And Flash plug-in unit moving object is the object of real Flash plug-in unit, so the method provided by calling the GetIDsOfNames function of Flash plug-in unit moving object, Flash plug-in unit moving object can be allowed to obtain the dispatch id of pending method, and then this dispatch id is returned to Flash plug-in unit by communication window and acts on behalf of object by Flash plug-in unit moving object.
Subsequently, method 300 enters step S303, and wherein the instruction performing pending method in script in object interception page process acted on behalf of by Flash plug-in unit, and this instruction is sent to Flash plug-in unit moving object. Specifically, after the dispatch id that object obtains pending method acted on behalf of by Flash plug-in unit, this dispatch id is fed back to the page, conveniently next step instruction that will perform Invoke (ID) of flow process page process, present method tackles the instruction of the Invoke (ID) of page process here, and the instruction of Invoke (ID) is sent to Flash plug-in unit moving object.
Subsequently, method 300 enters step S304, and wherein Flash plug-in unit moving object is by performing instruction, performs pending method in script, then execution result is returned to Flash plug-in unit and acts on behalf of object. Specifically, Flash plug-in unit moving object performs the instruction of Invoke (ID), thus perform method pending in script, obtain Flash version number, and Flash version number is returned to Flash plug-in unit and acts on behalf of object, then Flash plug-in unit is acted on behalf of object and Flash version number can be fed back to the page.
