Embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, embodiments of the invention provide the method for positioning searching information in a kind of browser, comprising:
Step 11, obtains the page script that browser is asked;
Step 12, according to described page script, plays up in the page window of described browser by webpage;
Step 13, in described page window, obtains the keyword that will search of input;
Step 14, in described page script, injects and searches script;
Step 15, searches script according to described, obtains the web page element with described Keywords matching.
In this embodiment of the present invention, by downloading in local described page script, injecting and searching script; Search script according to described, obtain the web page element with described Keywords matching, thus avoid and search in render engine, namely search in webpage, effectively improve search efficiency.
Preferably, in the above-described embodiments, in described page script, inject the step of searching script and comprise:
In described page script, the insertion script function provided by browser kernel, searches script described in injection.Particularly, the interface function of the insertion script that can be provided by browser kernel, searches script described in injection; Certainly, in page script, inject the method for searching script and be not limited to the mode that the present embodiment provides, self-defining mode can also be comprised and inject.
In of the present invention in another embodiment, comprise on the basis of above-mentioned steps 11-15, search script according to described, obtain comprising with the step of the web page element of described Keywords matching:
Search the browser object in script described in parsing, obtain the node tree of this browser object; Particularly, described in parsing, search the chained list that browser object in script is corresponding, the node tree that the multiple nodes obtaining described browser object are formed;
The node matched with described keyword is searched in described node tree;
The web page element that the described node that acquisition finds is corresponding.
Wherein, this searches in script the data structure with a DOM, this DOM is a browser object, by the mode enumerated, can list each node of this DOM, this node is as being arbitrary web page element that page script comprises, as passage in webpage, a pictures, animation etc., wherein node here also may comprise node, and these nodes can be enumerated with the form of tree or chained list; Certainly, also according to a transformation rule, chained list can be converted to tree construction or convert tree construction to chained list, not limiting in the node of this browser object concrete manifestation form the present embodiment in enumeration process.
When obtaining web page element corresponding to the described node that finds, as being all nodes in the described chained list of traversal or node tree, and the present node that travels through of judgement whether with described Keywords matching.
As shown in Figure 2, in another embodiment of the invention, on the basis comprising above-mentioned steps 11-15, can also comprise after step 15:
Step 16, searches script according to described, plays up the described web page element found at the page window of described browser according to the display effect arranged; Particularly, if find the node with Keywords matching, then calls application interface function, current display position from the node of Keywords matching and display styles are set to described chained list in or other node in node tree different; Wherein, comprising: be the explicit identification etc. that runic shows, the explicit identification of different colours, the explicit identification of amplification or font are floated by the curriculum offering corresponding with the node of described Keywords matching.
The above embodiment of the present invention by injecting a segment search script in the page script played up, by this search define in script search logic, the web page element corresponding with the keyword inputted is searched in web page windows, such one side, do not need to utilize render engine, the resource expended when making browser perform locating function is few, and search efficiency correspondingly improves; On the other hand, be no longer by render engine from Web browser downloading web pages script, play up, while search; But slightly make an amendment (namely inject and search script) downloading to local page script in this locality, just can be implemented in this locality and process, just can realize the locating function of web page element, thus improve search efficiency.
