How to know the target element that raised the event in the ajax response callback?

I am posting to the server using jquery ajax using $.post. After server returns the response, I process the response in the callback function. In this callback function, how can I know which element was clicked on. Please check the following. In the function handleServerResponse, I would like to know the DOM element that raised this event. Precise I want to access the $(this) element availabl开发者_如何学运维e in handleFavouritesUI function. I am using jquery with ASP.NET MVC.

        }
    }  


</script>

Change the handleServerResponse to an inline function...

function handleFavouritesUI(e) {
    var link = $(this).attr("href");

    $.post(link, function(data,textStatus){
        var targetElement = null;
        if (!response.success) {
            showMessage(targetElement, response.reason, true);
        }
        else {
            // See, the link object still holds the same reference.
            link.fadeOut().fadeIn();
        }
    });

    e.preventDefault();
    return false;
}
