Regular Expressions in JavaScript for URL Capture

Question

I am not too good with Regular Expressions in Javascript. Does anyone know an efficient way to capture the last portion of a URL???

I have the following URL:

<         


        

Answer 1

There are built in methods for this:

window.location.pathname.split("/").pop()

This will get everything after the domain name (window.location.pathname), then split it by forward slashes (split("/")), then return the last item of the array returned by split(), (pop()).

Answer 2

You can use following code snippet

var loc = location.href; 
var lastPart = loc.substr(loc.lastIndexOf('/') + 1);

Answer 3

You can use split by / and get the last element of srray:

var last = 'http://localhost:3000/developers/568d3c3c82eea6e6fb47c236'.split('/').pop();
//=> 568d3c3c82eea6e6fb47c236

Answer 4

You don't need a regular expression; just use lastIndexOf method:

var developerID = url.substr(url.lastIndexOf("/") + 1);
