jQuery get last part of URL

Question

I have a series of pages where I need to get a specific code for a button. I want to put the code which is in the url into a variable with jQuery.

An example URL is www.example.com/folder/code/12345/

I want to get the number part in a variable called (siteCode)

Thanks in advance for any answers.

jquery / Pseudo code:

var siteCode;

// start function
function imageCode(){
     siteCode // equals number part of URL
     $('.button').attr('src', 'http:www.example.com/images/'+siteCode+'.jpg');
}

Answer 1

I'd suggest:

var URI = 'www.example.com/folder/code/12345/',
    parts = URI.split('/'),
    lastPart = parts.pop() == '' ? parts[parts.length - 1] : parts.pop();

You can use the following code to get the last part of the url.:

var value = url.substring(url.lastIndexOf('/') + 1);
