Is it possible....?

...to kill a function that is looping via timeout from another function?

I suppose you could do something like it... Instead of looping you could use setInterval( expression ,  timeout ) to call your function every timeout milliseconds. setInterval returns an ID of sorts that can be used to cancel it. Consider this:

 

function loop() {
     // code to repeat
}

var interval = setInterval("loop()", 1); // run loop() every millisecond
setTimeout("clearInterval(interval)", 5000); // cancel in 5 seconds
