Passing an URL parameter to a href link using Javascript

Question

I have the following code working to pass a URL parameter to a form tag:

Answer 1

Change the function onload to this:

function onLoad() {
   var value = getQueryVariable("ID");
   var e = document.getElementById('your-field');
   e.value = value;

   var url = "http://www.mysite.com?source=" + value;
   var element = document.getElementById('YOUR_<A>_ELEMENT_ID');
   element.setAttribute("href",url)
}

I'm using the piece of code that Joao Almeida suggested so his example using jQuery works good too.

Good Luck!

Answer 2

You should give an id to you link, like this:

<a id="YOUR_ID" href="#" >

And then you have two ways to solve the problem, use pure Javascript or use jQuery:

IF you use jquery you can use your onLoad function and inside inject the following:

var url = "http://www.mysite.com?source=" + value;
$("#YOUR_ID").attr("href",url)

OR using pure javascript:

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