Wait/sleep before window.close()

Question

I try to set up a simple logoff-page which should close after 3 seconds.

Regarding this Question is it possible to wait before that action?

<script type="text/javascript">
sleep(3000);
window.open('', '_self', ''); 
window.close();
</script>

With the sleep nothing happens at all.

Edit:

The solution of @Sidius works well in IE without a prompt.

Unfortunately Firefox blocks the Script:

Scripts can not close any windows that were not opened by the script

Answer 1

try this:

window.open('', '_self', '');
setTimeout(function(){
   window.close(); 
}, 3000);

Edit: I think firefox might be a little more strict with the

window.open()

function. You might want to give values to the function's constructor.

window.open(URL,name,specs,replace); 

In example:

window.open("", "", "width=200, height=100");

Answer 2

You can use setTimeout() API to achieve the same -

setTimeout(window.close,3000);
