Question

I’m wondering if there’s a way to make setInterval clear itself.

Something like this:

setInterval(function () {
    alert(1);
    clearInterval(this);
}, 2000);

I want it to keep checking thing if it’s finished it will stop.

Try this way:

var myInterval = setInterval(function () {
    alert(1);
    clearInterval(myInterval);
}, 2000);

Alternative way is using setTimeout() if you know it is just one time call.
