Jquery navigation: enter different pages, and the corresponding navigation text is selected

Hello! It takes some time. The simple method is to add the #1, #2, #3 identifier after each link address.
Then call the Jquery method.
$ (Function (){
Var url = document. location. href;
Var menuId = url. split ('#') [1];
If (menuId = null)
{
MenuId = 1;

}
Var num = 0;
$ ("# Aaa ul"). find ("li"). each (function (){
Num ++;
If (num = menuId)
{
$ (This). addClass ("current ");
}
});

});

Hope to help you!

How does jquery control the navigation menu of the current page?

For example, the <div class = "nav"> <a href = "index.html"> homepage </a> <a href = "product.html"> product </a>
The following html content:
<Div class = "main">
<Div class = "content"> homepage content </div>
<Div class = "content"> product content </div>
<Div class = "content"> case center content </div>
</Div>
As for class = "content", you can add it yourself to facilitate jQuery's acquisition, without this style class.
<Script type = "text/javascript">
$ (Document). ready (function ()
{
Var tabs =$ ('. nav> ');
Var cons = $ ('. main> div. content ');

Tabs. first (). addClass ("now"). show (); // The first display by default
Cons. first (). show (). nextAll (). hide (); // The first display is displayed by default, and others are hidden.
Tabs. each (function (index ){
$ (This). mouseover (function (){
$ (This). addClass ("now"). siblings (). removeClass ("now ");
Cons. eq (index). show (). siblings (). hide ();
});
});

});
</Script>
