The problem is that you're getting the div with the Id imagePreview
, when the div in the form have the imagePreview
CSS class, what you can do is either give the div the required id, more less like this:
<div id="imagePreview"></div>
Or, if you will have multiple divs with the same class get them using jQuery like this:
$(".imagePreview").each(function(index){
//Do Something
});
Or:
var pic_div = $(".imagePreview")[0]
