Description
Technical field
The present invention relates to Internet technical field, particularly a kind of method and system of from webpage, obtaining 2 D code information.
Background technology
Two-dimension code (2D barcode) develops on the bar code basis, and the chequered with black and white figure that (two-dimensional directional) distributes on the plane according to certain rules with certain specific geometric figure is used for recording data information.It utilizes " 0 ", the concept of " 1 " bit stream that constitutes the computer-internal logical foundations dexterously on coding, use several geometrical bodies corresponding with scale-of-two to represent the literal numerical information.Because, two-dimension code has the bigger advantage of quantity of information compared to bar code, therefore in the modern commerce activity, obtained very using widely, as: product false proof/trace to the source, advertisement pushing, web site url, data download, commodity transaction, location/navigation, electronic certificate, vehicle management etc.
At present, the identifying of two-dimension code generally is after obtaining image in 2 D code by image input device (first-class as making a video recording) or photoelectric scanning device, and the image in 2 D code that automatic decoding recognition is obtained is to realize the automatic processing of information.
Along with the development of portable terminal and Internet technology, people more and more conduct interviews to webpage by portable terminals such as mobile phones.And have following problem in the process by the mobile terminal accessing webpage: exist some two-dimension code image in the webpage, and based on the reason of the recognition method of aforementioned present two-dimension code, portable terminal can't directly obtain relevant two-dimension code institute canned data in the webpage.If want to obtain corresponding information, carry out corresponding identification again after just need utilizing other terminal to take or scan to obtain image in 2 D code, user's experience is relatively poor.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment and accompanying drawing, the present invention is described in further details.At this, exemplary embodiment of the present invention and explanation thereof are used for explanation the present invention, but not as a limitation of the invention.
Embodiment one
Fig. 1 is the process flow diagram that obtains the method for 2 D code information from webpage.As shown in the figure, should from webpage, obtain the method for 2 D code information, comprise:
S1, each node in the traversal webpage judges whether present node is the picture node;
Concrete, can come by the DOM Tree of webpage each node of webpage is traveled through.DOM Tree refers to by DOM html page be resolved, and the HTML tree tree structure and the corresponding access method that generate.
S2 if present node is the picture node, then obtains the pictorial information of this picture node;
S3 according to the pictorial information that obtains, judges whether this pictorial information is two-dimension code image;
Here, we can be sent to described pictorial information the two-dimension code image recognition unit and carry out two-dimension code identification, whether can successfully identify two-dimension code according to this recognition device and judge whether this pictorial information is two-dimension code image.
S4 if this pictorial information is two-dimension code image, then identifies this two-dimension code image, obtains the 2 D code information of storing in this two-dimension code image;
S5 sets up the corresponding relation between this 2 D code information and the respective two-dimensional sign indicating number picture node.
The embodiment of the invention may be implemented in the browser in the specific implementation.When user's open any browser browsing page, after having loaded, webpage can start the above-mentioned method of from webpage, obtaining 2 D code information.The method that the embodiment of the invention provides is identified each picture node in the webpage one by one, be two-dimension code image if successfully identify picture, then obtain the 2 D code information of this picture and set up corresponding relation with this picture node, when carrying out associative operation, can obtain the corresponding 2 D code information of this picture node in order to the user.By said method, the user need not to utilize other terminal to take or scan to obtain relevant 2 D code information, but can directly can obtain relevant 2 D code information by this browser, and is convenient for users.
Should be pointed out that the method that the invention described above embodiment provides is not limited in the portable terminal use, suitable equally in fixed terminals such as PC.
Embodiment two
Owing to have part picture node not show in the webpage, and two-dimension code image must show at webpage.Therefore, in the present embodiment, whether we also show to come further according to the picture node is screened the picture node, to improve the treatment effeciency of this method.As shown in Figure 2, preferably, if described present node is the picture node, then obtain the pictorial information of this picture node, comprising:
S21 if present node is the picture node, judges then whether this picture node shows;
S22, if this picture node do not show, then ignore this node, do not deal with.
S23, if this picture node show, then obtain the pictorial information of this picture node.
As previously mentioned, because two-dimension code image must show at webpage, therefore the picture node that does not show is inevitable is not our needed two-dimension code image node.We can filter out the two-dimension code image node faster by above-mentioned determining step, improve the treatment effeciency of this method.
About the judgement whether node shows, whether we can be " none " by " display " property value in the render tree of this node correspondence, and perhaps whether " visibility " property value is that " hidden " judges.For example,＜img src="/images/LOGO.png "/style=" display:none; "〉namely illustrates the node of this node for not showing, do not need that therefore it is carried out two-dimension code image and judges.
