How to limit the number of iterations done by setInterval

Question

I display video ads to my users. I don\'t host these ads by the way; I get them from another company.

When ever an ad is clicked it leaves a cookie in the user\'s b

Answer 1

This should do it:

function checkCookie() {
    var cookie = getCookie("PBCBD2A0PBP3D31B");
    if (cookie != null && cookie != "") {
        alert("You clicked on an ad");
    }
    if (counter > 10) clearInterval(clr);
    counter++;
    clr = setInterval(function(){checkCookie()}, 10000);​
}
var counter = 0;
checkCookie();
