The BeginRequest() Method

Listing 3. The BeginRequest() method acts as an event handler for the beginRequest method. It starts an interval timer that calls an animation method.

function BeginRequest(sender,args)
{
    intervalID = window.setInterval("Animate()", 500);
}

function Animate()
{
    var div = $get("divAnimate");
    div.className = GetCssClass(div.className);
}

function GetCssClass(currClass)
{
    return (currClass=="DottedLines")?"SolidLine":"DottedLines";

}
