Javascript Regex: surround @_____, #_____ and http: // ______ with anchor tags in one go?

Question

Related (but slightly different):

Surround all instances of @________, #___________ and http: // _________ with anchor tags?

I would like to combine all instances @_______, #________and http://________with anchor tags in a single pass.

For example, consider this Twitter post:

@Spreadthemovie fast brown fox jumps through a lazy dog ​​#cow http: // URL

Running with the desired regular expression pattern will give:

The quick brown fox <a href="a">@Spreadthemovie</a> jumps over the lazy
dog <a href="b">#cow</a> <a href="c">http://URL</a>

Only surrounding words starting with @, #or http://so as [e-mail] to become dog<b>@gmail.com</b>.
