I am trying to use the youtube data api to generate a video playlist. However, the video urls require a format of youtube.com/watch?v=3sZOD3xKL0Y, but what the api generates is youtube.com/watch?v=3sZOD3xKL0Y&feature=youtube_gdata. So what I need to do is be able to select everything after and including the ampersand and remove it from the url. Any way to do this with javascript and some sort of regular expression?

Simple:

var new_url = old_url.substring(0, old_url.indexOf('&'));

Modified: this will remove all parameters or fragments from url

var oldURL = [YOUR_URL_TO_REMOVE_PARAMS]
var index = 0;
var newURL = oldURL;
index = oldURL.indexOf('?');
if(index == -1){
    index = oldURL.indexOf('#');
}
if(index != -1){
    newURL = oldURL.substring(0, index);
}

Wow. That was lightning fast. I actually discovered that I'll need to pull a different node from the feed though, that is unique. How would I extract just the id passed just after video: in this tag - tag:youtube.com,2008:video:3sZOD3xKL0Y –  mheavers Jan 10 '11 at 22:04

Example: http://jsfiddle.net/SjrqF/

var url = 'youtube.com/watch?v=3sZOD3xKL0Y&feature=youtube_gdata';

url = url.slice( 0, url.indexOf('&') );

or:

Example: http://jsfiddle.net/SjrqF/1/

var url = 'youtube.com/watch?v=3sZOD3xKL0Y&feature=youtube_gdata';

url = url.split( '&' )[0];

You could use a RegEx to match the value of v and build the URL yourself since you know the URL is youtube.com/watch?v=...

http://jsfiddle.net/akURz/

var url = 'http://youtube.com/watch?v=3sZOD3xKL0Y';
alert(url.match(/v\=([a-z0-9]+)/i));

Hmm... Looking for better way... here it is

var onlyUrl = window.location.href.replace(window.location.search,'');
