Stop scheduled JavaScript execution

Question

I have a function, where I define lots of setTimeout() functions . When user presses the button, it's starting the execution.

How can I cancel it ?

Is there any way to cancel ALL timeouts (assuming that I have multiple without the name)

// start timer
var timer = setTimeout(...);

// cancel timer
clearTimeout(timer);

Pass the timer ID returned by setTimeout to clearTimeout.

Use clearTimeout:

var timer = setTimeout(function(){ alert("hello!"); }, 3000);   

...

clearTimeout(timer);

The function setTimeout() returns an ID you can use to clear the timeout. You'll have to keep track of the timeouts, and clear them manually:

var timeoutID = setTimeout( scheduledFunction, time );

// do stuff...

//clear the timeout:
clearTimeout( timeoutID  );
