.attr('href') returning undefined

Question

I am using a simple JQuery solution to get the href from a link and apply it to a click event. This works in Webkit and Gecko browsers, however Internet Explorer (7 & 8) keeps displaying the href location as undefined . Anyone got a fix for this? Can help me solve this? Much appreciated if so.

 $('table tr').click(
    function () {
        var element = $(this).attr("class");
        var hrefLocation = $('#'+ element +' .deal-holder a').attr('href');
        alert(hrefLocation)
        window.location.href = hrefLocation;
        return false; 
    }
);

HTML is simple:

 <tr class="QRG">
    <td class="blue"><a href="#QRG">QRG</a></td>
    <td>Company Sale</td>
    <td>Technology</td>
 </tr>


 <div class="deal" id="QRG">
      <p><span class="js">Overview</span><span class="no-js">Enham</span></p>
      <div class="deal-holder">
         <div class="image-holder">
             <img src="../assets/images/enham.gif" alt="" height="70" width="150" />
         </div>
         <p>Enham is a charity established in 1918, which delivers a wide range of essential services that provide choice and empowerment to disabled people to make their own decisions about their lives.

Nothing jumps out at me at being wrong.

First make sure your using the latest version of jQuery as that can sometimes help.

I change your code so the link within the tr has the click event:

$('table tr a').click(function (e) {
    var element = $(this).closest('tr').attr("class"),
        hrefLocation = $('#'+ element +' .deal-holder a').attr('href');
    alert(hrefLocation)
    window.location.href = hrefLocation;
    e.preventDefault();
});

I did a demo here and it works in IE 7,8 and 9. Hope this helps.

Without knowing the rest of your html code is difficult to know exactly what's your problem, the behaviour depends greatly on how your html is structured... But doing a quick test here it works: Example , just uses the $(this) pointer to get the child link.

Answer 3

You may need to select the first element in the group of hyperlinks.

$('table tr').click(
    function () {
        var element = $(this).attr("class");
        var hrefLocation = $('#'+ element +' .deal-holder a').eq(0).attr('href');
        alert(hrefLocation)
        window.location.href = hrefLocation;
        return false; 
    }
);

Answer 4

Try wrapping it in the ready function.
IE could be trying to add the event to the object, before it's in the DOM:

$(document).ready(function(){

   $('table tr').click(
      function () {
         var element = $(this).attr("class");
         var hrefLocation = $('#'+ element +' .deal-holder a').attr('href');
         alert(hrefLocation);

         window.location.href = hrefLocation;
         return false; 
      });

});
