JS Control navigation Menu tab

Click to the new page, you must use JS in the new page to determine which display, if you are the current position of the tab style name: selected,

If you want the second one to be selected after the new page, you can only

Documengt.getelementbyid ("Navigation"). getElementsByTagName ("Li") [1].classname= "Selected";

That's it, okay?

Navigation This is the label for the navigation div layer's ID Li as the front row, formatted as follows

<div id= "Navigation" >
<ul>
<li> Navigation </li>
<li> Navigation </li>
</ul>
</div>

Or
<ul id= "Navigation" >
<li> Navigation </li>
<li> Navigation </li>
</ul>

<script type= "Text/javascript" >
Documengt.getelementbyid ("Navigation"). getElementsByTagName ("Li") [1].classname= "Selected";
</script>

Method Two

Function Doclick_down (o) {
  o.classname= "Menua";
  var J;
  var id;
  var e;
&n Bsp for (Var i=1;i<=11;i++) {
    id = ' down ' +i;
    j = document.getElementById (ID) ;
    e = document.getElementById ("D_con" +i);
    if (id!= o.id) {
      j.classname= "menu";
      E.style.display = "None";
   }else{
  e.style.display = "block";
   }
 }
& nbsp
Window.onerror = function () {return true};
</script>
