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

try this worked for me

/^((ftp|http[s]?):\/\/)?(www\.)([a-z0-9]+)\.[a-z]{2,5}(\.[a-z]{2})?$/

that is so simple and understandable
