Copy Code code as follows:

<meta http-equiv= "Content-type" content= "text/html; Charset=utf-8 "/>
<title></title>
<script type=text/javascript src= "Alabel.js" ></script>
<style type= "Text/css" >
. Curr{background:blue;display:inline;}
</style>

<body>
<div class= "Clmenu" >
<span><a href= "#" >1</a></span>
</div>

</body>

In the Alabel.js:
Copy Code code as follows:

Window.onload = function ()
{
var Aspan = document.getElementsByTagName ("span");
var i = 0;
for (i = 0; i < aspan.length; i++)
{
Aspan[i].onclick = function ()
{
for (i = 0; i < aspan.length i++) Aspan[i].classname = "";
This.classname = "Curr";
};
}
};

This enables you to add a red background to a label when you click it.

Note: The display in the Curr attribute cannot be block, otherwise the added background is an entire line.
