jQuery to parse our a part of a url path

Question

I need to parse long urls and set a variable (category) equal to one of the /folders/ in the path.

For example, a url that is

http://example.

You can fetch everything after the "/community/" with a regular expression:

var url = "http://www.example.com/community/whatever";
var category = "";
var matches = url.match(/\/community\/(.*)$/);
if (matches) {
    category = matches[1];   // "whatever"
}

If you want to get only the next path segment after community and nothing after that segment, then you could use this:

var url = "http://www.example.com/community/whatever/more";
var category = "";
var matches = url.match(/\/community\/([^\/]+)/);
if (matches) {
    category = matches[1];    // "whatever"
} else {
    // no match for the category
}
