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?
Try this:
url.replace("http:\/\/","");
Like bedwyr said. :)
This will match only at the beginning of the string and will catch https as well:
url.replace("^https?:\/\/","");
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!
