How do I remove "http://" from a string in actionscript?

Question

This one may seem basic but I don't know how to do it - anybody else?

I have a string that looks like this:

private var url:String = "http://subdomain";

What regex do I need so I can do this:

url.replace(regex,"");

and wind up with this?

trace(url); // subdomain

Or is there an even better way to do it?

Answer 1

Try this:

url.replace("http:\/\/","");

Answer 2

Like bedwyr said. :)

This will match only at the beginning of the string and will catch https as well:

url.replace("^https?:\/\/","");

Answer 3

ActionScript does indeed support a much richer regex repetoire than bewdwyr concluded. You just need to use an actual Regexp, not a string, as the replacement parameter. :-)

var url:String;
url = "https://foo.bar.bz/asd/asdasd?asdasd.fd";
url = url.replace(/^https?:\/\//, "");

To make this perhaps even clearer

var url:String;
var pattern:RegExp = /^https?:\/\//;
url = "https://foo.bar.bz/asd/asdasd?asdasd.fd";
url = url.replace(pattern, "");

RegExp is a first class ActionScript type.

Note that you can also use the $ char for end-of-line and use ( ) to capture substrings for later reuse. Plenty of power there!
