pass loop variable into setTimeout function

I have code that looks like the following:

$(document).ready(function() {
    $("#sendButton").click(function () {
        for (var i = 0; i < 119; i++) {
            setTimeout(function (i) {
                proName = proDatabase[i][0];
                proChamp = proDatabase[i][1];

...

When I run it, I get an error saying that "proDatabase[i] is undefined"... meaning the value of i in the scope of that setTimeout function is undefined. I'm trying to pass the value from the loop into the setTimeout function so that the loop executes once per second (it's currently working), so that I don't make too many AJAX calls to the server too quickly.

Despite trying to pass (i) in, it still registers as undefined.

Any ideas on this one?

Thanks!

where does proDatabase come from? And show the rest of the code – dave Aug 20 '15 at 02:56

Add `i` add the third argument to `setTimeout`, and it should work. i.e. `setTimeout(fn, time)` to `setTimeout(fn, time, i)` – PitaJ Aug 20 '15 at 02:59
thanks, that worked! – Vranvs Aug 20 '15 at 05:44
