Parameter description:

1.MENUID: The ID of the link group;
2.classcur: The style class name when highlighted.

Call Method:

Window.onload=function Highthis () {Highurl ("Youid", "Youhighclass");}
The first method is to determine whether the HREF value is contained in the browser's current URL value by traversing the href value of the link group. This method has some limitations, for example, the menu in the IFRAME can not be judged; The second method is more widely used, the realization of the idea is relatively simple, that is, through the judgment click, to load the highlight style.
