Find a element by URL to apply case _javascript tips

Give an example of a previous project: When you add a student, there is no class data. Need to automatically jump to the class display page.

Question: Students, classes and other data is placed in the IFRAME inside the JSP. The student-managed button is on the Main.html menu bar.

Mian Page Menu

Class Management:

Student Management:

The JSP in the IFRAME is constantly changing.

Workaround:

Student management JSP, find the parent form's class management <a> tags by ID, and click

Copy Code code as follows:

$ (window.parent.document). Find ("#folder_12"). Click ();

Later, the menu bar changed to dynamic, menu ID is also the dynamic of nature.

Want is to get <a&gt by URL, and click.

Copy Code code as follows:

<a id= "folder_14" onclick= "changecontent" (' classmanager/classlist.do ', this); "onfocus=" This.blur () "href=" Javascript:void (0); "target=" MainFrame "> Class management </a>

To get is the changecontent (' url parameter ') of the OnClick method

Look directly at the code:

Copy Code code as follows:

Console.info ($ (window.parent.document). Find ("a"));
$ (window.parent.document). Find ("#OutFolder a"). each (function (index, domele) {
var s = $ (Domele). attr ("onclick") + "";
var start = S.indexof (' classmanager/classlist.do ');
var str = domele.attributes.onclick.value;//Use JS to get onclick property value, search URL
var start = Str.indexof (' classmanager/classlist.do ');
if (start>0) {
$ (Domele). Click ();
}
});

Summary: The original has been using jquery to find ways to get the OnClick property, with indexof total error, plus "" space into string on the line
