Question

I am trying to grab the last part of the current url:

URL: http://example.com/test/action

I am trying to grab “action”.

The URL is always consistent in that structure. But it may have some extra params at the end.

This is in a rails app using the prototype framework. In rails it would be params[:id].

Answer 1

You could simply use .split() on window.location.href, and grab the last entry.

Example:

var lastPart = window.location.href.split("/").pop();
