setInterval repeat 3 time and kill

The difference is that you are not passing the id in as an argument to setInterval, but are defining it in a function that the callback (the function inside setInterval) has access to.

In it's simplest form, not this:

var idAnim;
function f(){
    idAnim = setInterval(function(id){
      clearInterval(id);
    }, 100, idAnim);
}

but this:

function f(){
    var idAnim = setInterval(function(){
      clearInterval(idAnim);
    }, 100);
}

I'm not quite sure what you're trying to do, but try starting with the code above and then modifying it to do what you want.
