Unobtrusive javascript vs IE

[benniaustin]

I'm having some problems with this unobtrusive javascript code.

The javascript turns any link with class="popup" into a popup window... in firefox. In Ie, the links just run normally.

function buildPopups() {
    var popupLinks=document.getElementsByTagName('a'); //this tells the browser what tags to apply this to
    for (var i=0;i<popupLinks.length;i++)
    if (popupLinks[i].getAttribute("class")=="popup") { //if the link has a class of popup...
      popupLinks[i].onclick = function() { //when it's clicked on...
        openWindow(this.getAttribute("href"));	//run the openWindow() function
        return false; //kills the link so it wont fire normally
      }
    }
  }
  function openWindow(myURL) { //popup Function
    window.open(myURL,'popup');
  }
  window.onload=buildPopups; //run the popup function when the page loads

Alright, nevermind I got it working.

It appears IE does not support the getAttribute() function, and will require me to use .className oh well.

It does support it, but you have to use getAttribute("className") rather than the standard getAttribute("class").
However, there's really no reason to use getAttribute() here...
