Hey I need to have a function run only once when the user scrolls. My problem is that I can't seem to figure out how to get .scroll to only check for that first scroll. I have come up with a working solution using a count, but I am hoping there is a better way to do it. I assume that it checking for a scroll constantly is just a waste of resources. My solution doesn't fix that problem, it only makes sure the function runs once. Here is what I have:

1. $(document).ready(function($) {
2.         if (window.location.href.indexOf('google.com/' || 'yahoo.com/') != -1) {
3.             alert('matched URL');
4.         else {
5.             alert('URL not matched');
6. });

What I can do that DOES work is:

1. $(document).ready(function($) {
2.         if (window.location.href.indexOf('google.com/') != -1) {
3.             alert('matched URL');
4.         }
5.         else if (window.location.href.indexOf('yahoo.com/') != -1) {
6.             alert('matched URL');
7.         else {
8.             alert('URL not matched');
9.         }
10. });

My problem is that I would like to try matching against a quite a few URLs, and I assume/hope there must be an easy way to do with just one if and else. Does anyone know of a solution? Thanks!
