js function to get filename from url
function, javascript
Solution
var filename = url.split('/').pop()
Problem
I have a url like http://www.example.com/blah/th.html I need a javascript function to give me the 'th' value from that. All my urls have the same format (2 letter filenames, with .html extension). I want it to be a safe function, so if someone passes in an empty url it doesn't break. I know how to check for length, but I should be checking for null to right?
