how to kill a setTimeout() function

Question

I use the setTimeout() function through my application but when its time to garbage collect. the method still runs and calls on a function. How do I stop it from calling on a certain function. I tried setting it to null but it doesnt work

Answer 1

setTimeout returns an reference to the timeout, which you can then use when you call clearTimeout.

var myTimeout = setTimeout(...);
clearTimeout(myTimeout);
