With Javascript, it is possible to execute some code NOT immediately after a function is called , but after a specified time interval. This is called timing events.
It's very easy to time events in JavaScript. The two key methods that are used are:
SetTimeout( ) - executes a code some time in the future
clearTimeout( ) - cancel' s thesetTimeout( )
Note: the seTimeout( ) and clearTimeout( ) are both methods of the HTML DOM Window object.
Tutorial
When the button is clicked in the example below, an alert box will be displayed after 5 seconds

{
var t= setTimeout ("alert ( '5 seconds!') ", 5000)
}
</script>
</head>
<body>
<form>
<input type="button" value="Display timed alertbox!" onClick="timedMsg( )">
