How to get URL parameter using jQuery or plain JavaScript?

Question

I have seen lots of jQuery examples where parameter size and name are unknown.

My URL is only going to ever have 1 string:

http://example.com?sent=ye         


        

Answer 1

There's this great library: https://github.com/allmarkedup/purl

which allows you to do simply

url = 'http://example.com?sent=yes';
sent = $.url(url).param('sent');
if (typeof sent != 'undefined') { // sent exists
   if (sent == 'yes') { // sent is equal to yes
     // ...
   }
}

The example is assuming you're using jQuery. You could also use it just as plain javascript, the syntax would then be a little different.
