Lightbox Effect JS Help Please

Question

I have the following code:

<script type="text/javascript" >

$(document).ready(function(){
$(".img").click(function(){
var address= $(this).attr("src");
$("#popup").fadeIn("slow");
$("#lightbox").attr("src",address);
});
$("#close").click(function(){
$("#popup").fadeOut("slow");
});
});
    </script>

Apparently in the string $("#lightbox").attr("src",address); the "src",address is a variable that should point the script to display the image associated with the source address in the lightbox popup. However it is not working for me. I thought that it could be that I have an overlay over the image thumbnails, however as you can see from the code below the overlay resides inside of the image class div. Any suggestions?

Answer 1

Your click handler is defined on the <div> element whose class is img . Thus, you're trying to get the src attribute from the <div> element instead of the <img> element:

$(".img").click(function(){
    // In this function, $(this) refers to <div class="img"> (not <img src="...">)
}

If you really need the click handler to be on the <div> element, try this:

$(".img").click(function(){
    var address= $(this).children().attr("src");
}

If instead you want the click handler on the <img> element, try this:

$(".img img").click(function(){
    var address= $(this).attr("src");
}
