JS to achieve the current click a label discoloration, other a label back to primary Colors

When a page has more than a label, and click will jump to the current page, how to achieve the click of the label color highlighting, other tags back to the primary colors.

Use JS to achieve:

Suppose the current page is "1.aspx"

1. Set the value for a label ID:

<a href= "1.aspx?id=1" id= "1" target= "_parent" > "" </a>
<a href= "1.aspx?id=2" id= "2" target= "_parent ">" </a>
<a href= "1.aspx?id=3" id= "3" target= "_parent" > "</a>

2. Write JS method:

<script>
    & (document). Ready (function () {
           var id = windows.ulr.substring (windows.ulr.IndeOf ("? id=" ), 1  //Get ID value
           var currta = document.getElementById (ID);   Gets the currently clicked a tag
           if (Currta!= null)   
               CurrtA.style.color = "#f00";
    });
</script>

For other cases, such as clicking on a label page does not jump, you can write this:

<a href= "#" onclick= "Changecss (This)" > "" </a>

<script> 
    function changecss (obj) {
        var alist = document.getElementsByTagName ("a");
        for (var i =0;i < alist. length;i++) {
            Alist[i].style.color = "#000";  Assign primary colors to all a
        tags
        obj.style.color = "#f00";   Make the current tab highlight
    }
        ///Of course, you can also use jquery $ ("a"). Removecss () and addcss () to achieve
</script>
