Try this:

JavaScript

var intervalID;
function doSomething()
{
    if ( condition )
    {
        clearInterval(intervalID);
    }
}
intervalID = setInterval(doSomething, 5000);

Hi RHL,

Its better to use setTimeout() instead of setInterval() since it better suits your requirement.

This is how you can do it

JavaScript

var timer = setTimeout("yourFunc()", 5000); //here it will execute after 5 secs

function yourFunc()
{
/*
your code
*/
if(timer)
clearTimeout(timer); //Here your timer will get stopped.
}

Note: If you use setInterval() then you need to use clearInterval() function to stop the timer
Hope this helps you a bit.

Regards,
RK
