Question

How do I manipulate a string using MooTools / JavaScript

I would like to replace all after /p/ in following url:

http://example.com/groups/browse/catId/14/p/1000-1500

Expected result:

 http://example.com/groups/browse/catId/14

Answer 1

Simple enough with regex:

var url = "http://example.com/groups/browse/catId/14/p/1000-1500";

console.log(url.replace(/\/p\/.+/, ""));
//-> "http://example.com/groups/browse/catId/14"

In the regex above, \/p\/ is /p/ with escaped slashes, followed by .+ which means match any character (except white space) one or more times.
