Embodiment
Below with reference to specific embodiment, technical scheme provided by the invention is described in detail, following embodiment should be understood and be only not used in for illustration of the present invention and limit the scope of the invention.
The invention provides a kind of webpage level memory return method, based on following webpage framework, namely have a main page, have multiple branch in main page, have multilayer sub-pages under each branch, each webpage should have corresponding level.In webpage opening procedure, likely arrive same sub-pages from multiple path, then also should return layer by layer along the path arrived when returning, therefore in the present invention, the level of each webpage dynamically generates.Based on above-mentioned thinking, the present invention includes following steps:
Steps A, first the every one deck under each branch of webpage is distinguished by webpage root name and level, namely different webpage root names represents different branches, webpage root name and webpage level is comprised in the link of the top layer of each branch of main page, the level of top level page is 0, and defines the variable of webpage root name and webpage level in every one deck page.
Then, when opening each layer page, need webpage root name and the webpage level of the last layer webpage obtaining current web page, and be effective level (webpage can opened to user when effective level refers to and returns at current page, whether webpage is that effective level can set as required) time obtain the webpage level of current web page, and in a session newly-built data stored in the information of current page, if current page is not effective webpage, then by the information transmission of last layer in lower one deck page of current page.In the present invention, session is structure of arrays, as shown in Figure 1, which includes the information respectively having the active layer page from top layer to current layer, for the specifying information of wherein one deck, comprise the link, webpage title, Navigation Picture etc. of webpage root name Backtype, webpage level backlevel, this webpage respectively.
