javascript - Regex to match url that starts with http or slash

Question

I'm trying to match a string that starts with either http:// or /.

This will pass...

http://www.google.com
/the/path/home.aspx

I'm pretty sure this will match http but I can't figure out how to fit in the optional /

/^(https?:\/\/)/i
