JavaScript Regex to match a URL in a field of text

Question

How can I setup my regex to test to see if a URL is contained in a block of text in javascript. I cant quite figure out the pattern to use to accomplish this

Answer 1

I've cleaned up your regex:

var urlexp = new RegExp('(http|ftp|https)://[a-z0-9\-_]+(\.[a-z0-9\-_]+)+([a-z0-9\-\.,@\?^=%&;:/~\+#]*[a-z0-9\-@\?^=%&;/~\+#])?', 'i');

Tested and works just fine ;)
