Question

I have the following code:

XService.start = function() {
  setInterval("XService.poll()", XService.pollInterval); }

This works great. However, when I do this (passing function as reference instead of having the string eval’d) it stops working:

XService.start = function() {
  setInterval(XService.poll, XService.pollInterval); }

Why? What am I doing wrong? Nothing else changes in my code. I also tried XService.poll() in the second version but no dice either. The documentation I read said leave the () out.

Help?

Edit: XService.poll is a function; XService.pollInterval is a number. Both are declared and assigned correctly.

Edit2: The XService code:

XService = {};
XService.pollUrl = "/Poll";
XService.pollInterval = 60000;
XService.poll = function() {
  $.get(this.pollUrl, null, null, "text"); }
XService.start = function() {
  setInterval(XService.poll, XService.pollInterval); }

Answer 1

is XService.poll a ‘function’ and ‘XService.pollInterval’ a number at that specific time?

Edit: Since you posted the code just now..

setInterval(

    function() {
        XService.poll();
    }, XService.pollInterval

);
