I'm looking to pass the handler of setInterval() to the internal function.

For example:

var id = setInterval(myfunction, "100000");

I'm looking to pass id to myfunction

I tried

setInterval(myfunciton(e), "10000");

but it didn't pass the variable.

Any ideas?

• javascript
• function
• setinterval
• anonymous

• Unless I misunderstood you, you can't pass a parameter that isn't even defined yet... – Maria Ines Parnisari Commented Aug 10, 2015 at 19:48

The id doesn't exist when you call setInterval, but it does exist by the time that the callback is called.

You would need to wrap the call in a function that uses the id in a call:

var id = setInterval(function(){
  myfunction(id);
}, 10000);

If you include the variable in the callback as it's passed in to setInterval, the callback is immediately executing with that argument.

What you need to do is create a closure:

setInterval(function() {
  myFunction(e);
}, 10000);

Also, the interval should be an integer, not a string.
