Question

** Update – trying to find the number of elements with an empty src **

I need to find the number of img elements with a populated src – eg: not src=””

Trying this:

  if(!$('div.previewWrapper div.previewContainer').find('img[src=""]').length > 0) {
    alert(numPhotos);
  }

HTML

 <div class="previewWrapper" id="thumbPreview3">
  <div class="previewContainer">
   <img src="" class="photoPreview" data-width="" data-height=""><span>3</span>
  </div>
 </div>

thx

Answer 1

Try this

var theNumber = $('div.previewWrapper div.previewContainer img[src=""]').length;

EDIT: jQuery has a neat != attribute selector
EDIT2: The OP now wants the number of images with empty src
