Jquery - Get Attribute using "this"

This may be something very easy but i can't seem to get this to work and im not sure why. I have jquery installed and i am trying to get an attribute of "this" element when i click on it. Right now my code looks like this:

url = $(this).attr("href")

When I call this function by clicking on a link, it tells me that the var "url" is undefined. So obviously it is not picking up the "this" when i click on the link. I am trying to pass the href of an anchor tag to use as my variable.

What am i overlooking? Again, i know this is something very simple but i can't seem to figure it out so thank you for taking the time to help me.

Thanks.

<script type="text/javascript">
url = "push1";

$("a").live("click", function(event) {
    event.preventDefault();     
    url = $(this).attr("href");
})
$.ajax({
    type: "get",
    url: "/"+url+".php",
    data: "",
    dataType: "html",
    success: function(html){
        jQuery('#Right_Content').hide().html(html).fadeIn(1000);
    },

})
;
</script>

html:

<body>

<a href="push1" >Image 1</a>
<a href="push2" >Image 2</a>  

<div id="Right_Content"></div>

</body>

Solution

This should work for you

$(function(){    
    $(".link").click(function(){
       var url=$(this).attr("href");
       alert(url);
        return false;

    });       

});

Assuming you are targeting all anchor tags with a css class called "link"

Here is the working example : http://jsfiddle.net/L99mM/2/

Edit: As per your code posted in the question

You should call preventDefault after your ajax call. and there is closing brackets should be after ajax call

$("a").live("click", function(event) {      
      var targeturl = $(this).attr("href");

      $.ajax({
               type: "get",
               url: "/"+targeturl +".php",
               data: "",
               dataType: "html",
               success: function(html){
                   jQuery('#Right_Content').hide().html(html).fadeIn(1000);
               }

           });  // closing for  ajax
        event.preventDefault(); 

  });  // closing for click  event binding
