Description
[technical field]
The present invention relates to browser plug-in and realize technology, particularly a kind of method and browser of expanding browser function.
[background technology]
Browser plug-in is the application that the function of browser is expanded.Existing browser plug-in is realized technology (browser being carried out the technology of Function Extension) and is mainly comprised following three classes: the ActiveX technology based on IE platform, can browser-cross platform NPAPI technology and in the Applet technology of supporting to realize on the browser of JAVA.These three kinds of browser plug-ins being realized to technology below introduces accordingly.
1, ActiveX is the proprietary technology on the WINDOWS platform of Microsoft.It uses COM(Component Object Model, component object model) technology, software part (being the primary control program of assembly and assembly) can be carried out alternately in network environment.COM technology is a kind of method across application and the shared binary code of language, define different application and in scale-of-two rank, carried out mutual standard, because ActiveX plug-in unit and browser meet such standard, therefore as long as ActiveX plug-in unit is with DLL(Dynamic Link Library, dynamic link library) form is registered to registration table, just can call for browser.Particularly, the process of browser loading ActiveX plug-in unit please refer to Fig. 1 and Fig. 2.
Fig. 1 is prior art while using ActiveX plug-in unit, webpage source file write example schematic.As can be seen from Figure 1, use ActiveX plug-in unit, in html document, need to use OBJECT label to identify, in the attribute of this label, also identified the GUID(Globally Unique Identifier of ActiveX plug-in unit in registration table, global unique identification symbol).Fig. 2 is the loading procedure schematic diagram of the ActiveX plug-in unit of prior art.As shown in Figure 2, first when browser loads html page, carry out DOM(DOM Document Object Model) conversion, in this process, find OBJECT label, just can from registration table, search ActiveX plug-in unit as corresponding in the GUID of appointment in the OBJECT tag attributes in Fig. 1, to obtain the position of corresponding ActiveX plug-in unit, according to this position, browser just can be loaded into corresponding ActiveX plug-in unit internal memory operation, realizes corresponding function.
2, NPAPI is a kind of browser plug-in technology that Netscape company proposes.It is the plug-in part technology of similar ActiveX, but it has defined the developing plug standard of a browser-cross, and the browser plug-in that meets NPAPI standard can be upper called at multiple browser (as Firefox, Chrome, Safari, Opera etc.).The conventional safe control of FLASH player, Alipay is all the plug-in unit that uses NPAPI technological development.
Please refer to Fig. 3, the schematic diagram of the loading procedure of the NPAPI plug-in unit that Fig. 3 is prior art.When browser starts, the file of the package types under load default path, and initialization plug-in environment (each plug-in unit is correspondingly registered in browser), in initialization, according to the standard of NPAPI, plug-in unit and browser can call respectively the function passes information that the other side provides, and simultaneously browser obtains the information in plug-in unit, with by plug-in registration to browser.When the page loads, in the process of resolving at DOM, find label as shown in Figure 4, browser is by judging in registered plug-ins whether have the plug-in unit consistent with the MimeType type shown in Fig. 4, if existed, create the example of this plug-in unit, to provide corresponding function to realize the expansion of browser function.When the page is destroyed, the plug-in unit example that before creates on the page is corresponding also can be destroyed, and when browser cuts out, will exit plug-in environment.
3, Applet be the applet of writing with Java language as the technology of plug-in unit, these programs are directly embedded in the page, are explained and are carried out, thereby realize the object of expansion browser function by Java-compliant browser.
Please refer to Fig. 5, Fig. 5 is the schematic diagram that prior art is used the page source file of Applet plug-in unit.Corresponding this page, the loading procedure of Applet is as follows: browser load page, when carrying out DOM parsing, find Appplet label, under the path (X) of Applet label definition, according to class title (Y), find corresponding applet class, and use Java Virtual Machine to such execution that makes an explanation, to realize the corresponding function of this Applet.
By above three kinds of prior aries, seen, the problem of existence is: (1), under the mode of ActiveX and NPAPI, exploitation browser plug-in all needs to meet specific communication standard, and this strengthens the difficulty of developing plug, thereby has affected spendable plug-in unit quantity; (2) above three kinds of methods all need to be carried out mark with special label in page source file to be loaded, could realize calling of corresponding plug-in unit; (3) above three kinds of methods are when loading browser plug-in, all need to specify viewing area (" width " and " height " attribute in can source file label corresponding from each method is found out) for plug-in unit;

[embodiment]
In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the drawings and specific embodiments, describe the present invention.
Script in this instructions all adopts JavaScript script to carry out in giving an example, but should be appreciated that, the script in the inventive method should not only limit to this.
In the present invention, browser has comprised script engine module and Scripting Agent module.Script engine module wherein, for mutual with script, and according to mutual situation, complete and Scripting Agent module between communication.Scripting Agent module, for the information of transmitting according to script engine, carries out relevant action.To said process, be introduced by specific embodiment below.
Please refer to Fig. 6, Fig. 6 is the schematic flow sheet of the embodiment of the present invention's method of expanding browser function, and as shown in Figure 6, method of the present invention mainly comprises the following steps:
The script engine module parses page script of S1, browser is determined non-protogenous example script to be created in page script in resolving, and the sign of non-protogenous example script to be created is sent to the Scripting Agent module of browser.
S2, Scripting Agent module create the java class example corresponding with above-mentioned sign according to the mapping relations in default plug-in description file, and create above-mentioned non-protogenous example script to be created according to this java class example.
S3, when script engine module is called the method for the non-protogenous example script having created in resolving, trigger Scripting Agent module and call the correlation method of the java class example corresponding with the non-protogenous example script having created and will call result and be back to script engine module.
Below above-mentioned steps is specifically described.
In step S1, browser is when loading a page, and script engine module is resolved the script in this page, determines non-protogenous example script to be created in the page in resolving.Non-protogenous example script refers to only by the definition in page script, the example script that cannot create.Particularly, the step of determining non-protogenous example script to be created comprises:
Judge quoting referent and whether exist in page script in internal memory, if this quotes referent, in internal memory, do not exist, determine that this quotes referent is non-protogenous example script to be created.
Please refer to code block 1:
<script language＝"Javascript＂>
alert(ExtCalendar.now())； （1）
</script>
Suppose that in code block 1, quote " ExtCalendar " referent does not exist in internal memory, think that " ExtCalendar " referent is non-protogenous example script to be created.
In addition, the embodiment of determining non-protogenous example script to be created in page script also comprises: example script to be created determined in the key word that creates action by characterizing in page script, and under judging example script to be created, whether class is defined in page script, if not, determine that example script to be created is non-protogenous example script to be created.
Please refer to code block 2:
In code block 2, by " new " key word (characterize creating the key word of action) wish, create example script " mailer ", if under it class Mailer in page script all without defining, think that " mailer " is non-protogenous example script to be created.
In step S1, script engine module is after determining non-protogenous example script to be created, this non-protogenous example script to be created sign is sent to Scripting Agent module, like this in step S2, Scripting Agent module just can find corresponding mapping relations according to this sign, thereby creates corresponding java class example and non-protogenous example script according to corresponding mapping relations.
Particularly, in step S2, Scripting Agent module reads plug-in description file, usings the sign of the non-protogenous example script that sends in step S1 as key word, searches the mapping relations of coupling in plug-in description file.
According to the content in cited above code block 1 and code block 2, be appreciated that, the sign of the non-protogenous example script sending in step S1, both can be the title (as " ExtCalendar " in code block 1) of this non-protogenous example script, can be also the title (as " Mailer " in code block 2) of class under this non-protogenous example script.Corresponding with it, the attribute of mapping relations in plug-in description file, the first attribute and the second attribute have been comprised, wherein the first attribute is for describing the title of non-protogenous example script or the title of the affiliated class of non-protogenous example script, and the second attribute is for describing the title of the java class corresponding with the first attribute.
Please refer to code block 3, code block 3 is the signal code of the mapping relations in plug-in description file:
The first attribute description in the mapping relations of above-mentioned code the second row the title (class name) of class under non-protogenous example script, the second attribute description the title (java class) of corresponding java class; The first attribute description in the mapping relations of the 3rd four lines the title of non-protogenous example script (instance name), the second attribute description the title of corresponding java class.
In step S2, the step of the java class example that Scripting Agent module creation is corresponding with the sign of non-protogenous example script to be created specifically comprises:
Determine the mapping relations that the property value of the first attribute in each mapping relations and the sign of non-protogenous example script to be created match, and create the example of the java class of the property value appointment of the second attribute in these mapping relations.
Because the sign of the non-protogenous example script to be created title that can be both this example can be also the title of class under this example, in step S2, when determining the mapping relations of coupling, in first property value that is identified at each mapping relations that only need to utilize step S1 to send over, carry out matched and searched.
Being designated of the non-protogenous example script for example sending in step S1 " Mailer ", in the second row mapping relations of code block 3, the property value " Mailer " of the first attribute matches, by these row mapping relations, can determine that corresponding java class is for " com.plugin.mailer ", utilize such class file, just can create corresponding java class example.Above-mentioned class file, can leave under default path, also can in mapping relations, add a new attribute for characterizing the deposit position (code block 3 is not shown) of java class file, if comprise such a attribute in mapping relations,, when creating corresponding java class, to the position of this property value appointment, remove to obtain class file to create corresponding java class example.
After having created java class example, in step S2, Scripting Agent module can be packaged as non-protogenous example script by this java class example, namely according to this java class example, creates the non-protogenous example script to be created of determining in preceding step S1.By this step, interaction mechanism has just been set up in Java space and script space, thereby can realize in subsequent step from the Java space of calling in script space, calls.Particularly, according to the step of the non-protogenous example script to be created of determining in java class example foundation step S1, comprise: according to the attribute of this java class example and method, determine the definition of non-protogenous example script to be created, and create this non-protogenous example script according to this definition.In the definition of non-protogenous example script to be created, determined that this non-protogenous example script has attribute and the method identical with the corresponding java class example having created, like this, in subsequent step, just calling of script space, can correctly be mapped to calling up of Java space.Same alike result described herein and method, identical in fact and to be not limited only to name identical, for example, if the corresponding relation of the method for the method of java class example and non-protogenous example script is described in plug-in description file, should determine same procedure according to this description.The java class example A for example having created has " read " method, and supposing has following two attribute: < in mapping relations ... java_m=read, instance_m=readme ... >
So should be appreciated that, non-protogenous example script to be created should be readme with the method name of the same procedure of the A having created, rather than read.
As preferred embodiment a kind of, the present invention does not describe the method for Java example and non-protogenous example script and the corresponding relation between attribute, but acquiescence is shone upon with identical title between the two.
According to foregoing description, should be appreciated that, " the calling the correlation method of the java class example corresponding with the non-protogenous example script having created " of describing in step S3, correlation method wherein, while existing corresponding relation between java class example and the method for non-protogenous example script to describe in plug-in description file, it can be method definite in this corresponding relation.As preferred embodiment, owing to the corresponding relation between java class example and the method for non-protogenous example script not being described in plug-in description file, thus correlation method be exactly java class example, there is the method for same names with the method for the non-protogenous example script called.The method of the non-protogenous example script that for example script engine module is called is " now " method, triggers " now " method that Scripting Agent module is called corresponding java class example.
In step S3, the method for calling arbitrarily a java class example while making to move due to the reflex mechanism of Java becomes possibility, and therefore, in the scope it will be appreciated by those skilled in the art that, above-mentioned call-by mechanism is not difficult to realize, and this instructions does not repeat this.
From code block 3, it can also be seen that, can also comprise the 3rd attribute (lifecycle) in the attribute of mapping relations, wherein this attribute is for describing the valid period of the object producing according to these mapping relations.The property value of the 3rd attribute can be during a page is loaded on destruction effectively page properties value, a browser be loaded on effective session attribute value of down periods or with a server interaction during effective Domain Properties value.In the mapping relations of code block 3 second row, what the 3rd property value " page " represented is exactly page properties value, and in the mapping relations of the 3rd four lines, what the 3rd property value " session " represented is exactly session attribute value.
Within the valid period of the 3rd attribute definition, the java class example and the non-protogenous example script that according to correspondence mappings relation, produce can exist always, the object of session attribute value (java class example and non-protogenous example script) for example, once create, all effective before browser cuts out, until browser cuts out just, destroyed, and the object of page properties value when being closed, will be destroyed current page.
Because the object of session attribute value and the life cycle of the page are irrelevant, can before loading, the page first create, and directly to call when the page loads, therefore, the present invention can also take a step forward and comprise at step S1:
Scripting Agent module determines that in plug-in description file, the 3rd property value is the mapping relations of session attribute value, and creates the java class example of this mapping relations appointment and the non-protogenous example script corresponding with this java class example.
