Replace substring within several urls

Question

My html:

<select onchange="getval(this);"> <option value="user1">user1</option> <option value="user2">user2</option> <option value="user3">user3</option> </select> <a class="local" href="http://subDomain.www.mysite.com">Site</a> <a class="local" href="http://subDomain.www.mysite.com/admin">Admin</a> <a class="local" href="javascript:open_wins('http://subDomain.mysite.com', 'http://subDomain.mysite.com/admin');">Both</a>

My script:

<script> function getval(sel) { $(document).ready(function() { var x = (sel.value); var regex = new RegExp(Globally replace the subdomain of urls on select change); $('.local').attr('href', function(i, val) { return val.replace(regex, x); }); }); } </script>

I want to be able to dynamically replace whatever the current subDomain string is, e.g., user1 with the option value I select from my form.

This script may not be elegant, but it works to replace a static string in the url. What I'm trying to do is replace everything between "http://" and ".", but try as I may, I cannot figure out the proper regex to do so.

You shouldn't have a $(document).ready within your getval function. It should be wrapping it if anything. — mVChr

You mean http://subDomain.mysite.com should become http://user1.mysite.com? — hjpotter92

hjpotter: Yes. And when I select user2 from my select box, user1 needs to become user2, etc. — user2521916

Explosion Pills: That almost works, but it leaves off the last ".", e.g., subDomain.www.mysite.com becomes user1www.mysite.com. — user2521916

function getval(sel) { var x = (sel.value); var regex = new RegExp(/http:\/\/\w+\./g); $('.local').attr('href', function (i, val) { return val.replace(regex, "http://" + x + '.'); }); }
