Question

My page’s URL is like this:

http://www.mydomain.com/directory/thisismy_page.html

Using JavaScript, I want to pull out the part of the page’s filename before the underscore. So in this example, I want:

thisismy

I currently have this:

var filename = location.pathname.substring(location.pathname.lastIndexOf("/") + 1);

But that pulls out thisismy_page.html. How do I “stop” it at the underscore so all I get is thisismy?

Answer 1

filename=filename.split("_")[0];

This splits it at the underscore and takes the first (or 0th part).
