hai erum,

i too surprised by seeing this kind of requirement

its working for the click event of button like this format

<input type="button" name="" value="Try it" onclick="myFunction()"/>

than this

<button onclick="myFunction()">Try it</button>

i dont know the reason exactly but i think this might be html version problem

we will wait for proper reason from anyone of experts here

Erum,

When the button is clicked your function will be called and the timer started. Just a few milliseconds after the call to setTimeout() your function will exit and the form is posted back to the server. When this happens you'll loose any environment or state. The timeout you set will no longer exist.

If you prevent the form from being posted back, you should find the timeout works fine. On line 18, try something like...

<form id="form1" runat="server" onsubmit="return false">
