How can I disable all setTimeout events?

I am using ajax and asp.net. iI have a javascript function which creates many other javascript functions with setTimeout. After asynchronous postback happenes, I want to disable all of these setTimeouted events. How can I do that?

If you can't get access to the code where the timer is set Nick's answer may not work, so all that I can think of is this hack.

It is a hack, use with caution!

// Set a fake timeout to get the highest timeout id
var highestTimeoutId = setTimeout(";");
for (var i = 0 ; i < highestTimeoutId ; i++) {
    clearTimeout(i); 
}

Basically it grabs the highest timer id and clears everything less than that. But it's also possible to clear other timers that you do not want to clear!

When you call setTimeout(), store the timer ID so you can clear it. If you're creating many timeouts, then an array is a good option for storing the IDs. For example:

var timeouts = [];
//then, store when you create them
timeouts.push( setTimeout( { ... }, 1000) );

Then when you want to clear them:

for (var i = 0; i < timeouts.length; i++) {
    clearTimeout(timeouts[i]);
}
//quick reset of the timer array you just cleared
timeouts = [];

As @Robert noted below, clearTimeout() won't throw an error if the timeout has already occurred, so there are no race/timing issues here.

Not sure if you can do this globally, but the most common method is to use clearTimeout. You pass the return value of setTimeout() to clearTimeout(), you could use a global var to store all timeout vars.

Firstly, I was using this code:

var x = setTimeout('');
for (var i = 0; i < x; i++)
    clearTimeout(x);

However, this peace of code did not work on Google Chrome. So I made improvement for this:

var x = setTimeout('alert("x");',100000); //It is very low probability that after 100 seconds x timeout will not be cleared
for (var i = 0; i <= x; i++)
    clearTimeout(i);

Finally, it is a hack, as it was mentioned in the comment above, so use it carefully.

Edit: fixed wrong variable used in loop (use i instead of x)

you can stop setTimeout() of one function in other function using clearTimeout()

var myVar;

function myFunction() {
  myVar = setTimeout(function(){ alert("Hello"); }, 3000);
}

function myStopFunction() {
  clearTimeout(myVar);
}
