Abstract
The invention discloses a webpage multi-language dynamic switching method based on a webpage browser engine. The method comprises the steps of: intercepting text inside a label and carrying out translation and dynamic replacement when the browser engine loads a webpage and parses to an appointed multilingual label. The invention also discloses a system for realizing the method. The system comprises an intercepting module and a multilingual storage and query module, which are embedded in the browser engine, wherein the intercepting module is used for intercepting the text in the multilingual label and transmitting to the multilingual storage and query module when the webpage browser engine carries out page parse; and the multilingual storage and query module is used for translating the intercepted text into appointed language and updating the text content. According to the multi-language dynamic switching method and system, by amending the bottom-layer code of the browser engine, the webpage language is only needed to be replaced once when the HTML (Hyper Text Makeup Language) page is parsed and is not needed to be replaced again when the page is loaded again, thus the webpage language dynamic switching efficiency is increased.
Description
Technical field
The present invention relates to homepages language switching field, especially a kind of webpage based on browser kernel engine is multi-lingual dynamically to be cut
Change method.The invention still further relates to realizing the system of the method.
Background technology
Multilingual switching at runtime to be realized in the browser interface of handheld device, the method generally adopting at present is to set
The multi-lingual character string of standby end storage, then runs javascript script, according to current in the page that browser loads
Language is arranged, and carries out dynamic replacement to the localized strings occurring in webpage.The shortcoming of this method is that browser adds every time
During contained network page, be required for extra perform script and be replaced, this brings extra expense to system, slowed down webpage be loaded into
The speed of display, and, javascript script is externally loaded localized strings, certainly will the cutting of running environment be related to
Change, i.e. frequently redirecting between script interpretation environment and multi-lingual storage environment, therefore, language switching efficiency is than relatively low.
Content of the invention
The technical problem to be solved in the present invention is to provide that a kind of webpage based on web browser engine is multilingual dynamically cuts
The side of changing, it can improve the efficiency of homepages language switching.
For solving above-mentioned technical problem, the multilingual switching at runtime side of the webpage based on web browser engine of the present invention
Method, comprises the following steps:
1) define the Multilingual label of html webpage, the text in this label is the literary composition needing to carry out multilingual switching at runtime
This；
2) build the dom tree of html webpage in browser engine before, insertion following steps:
When browser engine is resolved to Multilingual label, records this label, and intercept the text in this label；
According to the current language of the text, search the translation character string of the text, and replace this article with this translation character string
This original character string.
The invention solves the problems that another technical problem be provide a kind of system for realizing claim 1 methods described.
For solving above-mentioned technical problem, the multilingual switching at runtime of the webpage based on the web browser engine system of the present invention
System, includes:
Blocking module, is embedded in browser engine, in browser engine analyzing web page, multi-lingual to needing to carry out
The text of speech switching at runtime is intercepted, and sends multi-lingual storage enquiry module to；
Multi-lingual storage enquiry module, is embedded in browser engine, for receiving the text that blocking module transmission comes, and root
According to the current language of the text, content of text is translated and is updated.
A multilingual vocabulary is comprised, for storing the entry of different language in described multi-lingual storage enquiry module.
The present invention passes through to change the bottom code of browser engine, its html resolving is intercepted, in browser
Engine carries out web analysis, when obtaining webpage character string, carries out multi-lingual inquiry and dynamic replacement, with traditional operation
The method that javascript script carries out character string switching at runtime is compared, and the present invention only need to replace one in html page parsing
Secondary, need not switch again and perform script in page heavy duty, so that display efficiency improves more than one times.
Brief description
Fig. 1 is the flow chart that existing webkit parses html；
After Fig. 2 is the replacement flow process of the insertion present invention, the flow chart that webkit parses html.
Specific embodiment
It is that the technology contents to the present invention, feature and effect have and more specifically understand, in conjunction with the feasible enforcement of the present invention one
Example and accompanying drawing, details are as follows:
Webkit is a browser kernel engine increased income, and its source code clear in structure, it is easy to safeguard, is current main flow
One of browser kernel, on pc platform and handheld device, application is quite varied, is based especially on the hand-held of Android platform
Equipment, often first-selected webkit is as the core engine of its browser.The present embodiment have selected android1.5 as enforcement
Platform.
The flow process of webkit original parsing html refers to shown in Fig. 1, comprises the following steps:
1) loader that webkit is carried using it, from network or local loading html source code.
2) htmltokenizer (html segmenter) of webkit carries out morphological analysis to this html source code, obtains each section
Label (tag) and text object.
3) htmlparser (html resolver) receiving step 2 of webkit) analyze the morphology object obtaining, and solved
Analysis and process, then with these morphology objects as node, generate dom tree.
4) webkit renders to dom tree, and is plotted on display screen.
The present embodiment is modified to the bottom code of webkit, newly embedded in blocking module and multi-lingual in webkit
Storage enquiry module, blocking module is used for, when htmlparser parses, the text needing to carry out multilingual translation being intercepted,
And send to multi-lingual storage enquiry module translated.Be stored with multi-lingual storage enquiry module multilingual vocabulary, for blocking
Cut the text that sends of module and translate into the language specified.In addition, before modification webkit bottom code, the present invention is to html
Need the label carrying out the inline text of multilingual translation to arrange in webpage, in the present embodiment, be about set to ＜ multilang ＞,
For example, in source code ＜ multilang ＞ text ＜/multilang ＞, " text " is exactly the character needing to carry out multilingual translation
String.
After the modification of webkit bottom code, also there is respective change in the flow process that webkit parses html, new process of analysis
See shown in Fig. 2.Load html source code in webkit, and using htmltokenizer, it carried out after morphological analysis,
The htmlparser of webkit parses to each literal node.When htmlparser is resolved to ＜ multilang ＞ mark
During label, this label is inserted in dom tree, blocking module is just intercepted herein, records this label, then,
When htmlparser is resolved to plain text " text ", blocking module just sends this character string " text " to multi-lingual storage inquiry mould
Block.Multi-lingual storage enquiry module arranges (for example, Chinese) according to current language, searches and search translation word in multilingual vocabulary
Symbol string, obtains " text " two word.Multi-lingual storage enquiry module is back to webkit this translation character string and is intercepted place, will be original
Character string " text " replace with " text ", then, htmlparser by replace after character string be inserted in dom tree, by
Webkit is rendered to dom tree and is drawn and is shown on screen, so, just completes dynamically replacing to inherited literal node
Change.
