How to get the image size in jquery

I have a simple image gallery with different image size. I'm going to get the width of 开发者_如何学Gothe current image and assign it to it's parent div using jquery but I can't seem to get it working. Thanks for any help.

var imgWidth = $("#image").width();
$("#gallery").css({ width : imgWidth });

Sample HTML:

<div id="gallery">
 <img src="123.jpg" id="image" />
</div>

Your code seems ok. But you may be trying when the image hasn't been loaded yet. $(document).ready wouldn't help in this case. Try this:

$(window).load(function(){
  var imgWidth = $("#image").width();
  $("#gallery").width(imgWidth);
});

Hope this helps. Cheers

You need to specify "px"

Like so:

var imgWidth = $("#image").width();
$("#gallery").css({ width : imgWidth+"px" });

Assuming the image is loaded when your javascript is executing this should work. If not you'll have to place this code inside a $(window).load(function(){}); as Edgar says or possibly even a $("#image").load(function(){});.

You're going to kick yourself for this......

Your jsfiddle was set to use mootools not jQuery.
