I’m having trouble replacing some url variables in javascript. I’m trying to replace the value of &s= and &so=. Below is my code:

url = url.replace(/(s=).*?(&)/, '$1' + $("#sort_by").val() + '$2');
url = url.replace(/(so=).*?(&)/, '$1' + $("#sort_ord").val() + '$2');

The first replace works no problem, the s value is always replaced, but the so variable never seems to get replaced.

    Change your code to this:

    url = url.replace(/(s=)[^&]*/, '$1' + $("#sort_by").val());
url = url.replace(/(so=)[^&]*/, '$1' + $("#sort_ord").val());

    This should work with most URL (but not all URL as allowed by the RFC). This takes advantage of the fact that & is mostly used to delimit key-value pair in the query string of the URL.
