html - Append URL parameter to href with JavaScript

Question

I'm trying to append a query string parameter to a href on a page using some JS:

var url = "http://www.sitetest.com?source=" + value;
var element = document.getElementById('thislink');
element.setAttribute("href",url);

HTML

<a href="#" id="thislink">TEST THIS LINK</a>

So whatever parameter is in the URL needs to append to the link, its working however it puts in the current URL not the one I specify in "var url"? Thanks!

Answer 1

On your test page, have you checked the console?

Uncaught ReferenceError: value is not defined

The posted code will work fine if you assign a value to the value variable.
