An example of a previous project: when students were added, there was no class data. Need to automatically jump to the class presentation page.

Problem: students, classes, and so on are put into the iframe of the JSP. The student-managed button is in the menu bar on main.html.

Solutions:

Class management by looking up the parent form by id < A> TAB and click

$(window.parent.document).find("#folder_12").click();

Later the menu bar changed to dynamic, the menu id is dynamic.

What you want is to get by url. A> , and click.

<a id="folder_14" onClick="removeTopMenuCss();switchFolder(this.id);changeContent('classManager/classList.do',this);" onFocus="this.blur()" href="javascript:void(0);" target="mainFrame"> Class management </a>

What you want to get is the changeContent(’ url parameter ’) for the onClick method

Directly look at the code:

//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 the value of the onclick property and search the url
var start = str.indexOf (''classManager/classList.do');
if(start>0){
$(domEle).click();
}
});

Summary: I have been using jquery to find a way to get the onclick property, use indexOf to always report errors, plus "" space into a string
