You’ll need to enclose the code that you want to execute after the delay in a function (Func1()). This function will then be called with a delay, in our case from another function (Func1Delay()).
<script type="text/javascript">
function Func1()
{
alert("Delayed 3 seconds");
}
function Func1Delay()
{
setTimeout("Func1()", 3000);
}
</script>Then you simply call Func1Delay() which in turn calls Func1() but with a delay of 3000 milliseconds (3 seconds):
<body onload="Func1Delay()">
</body>
