Count images or "rel" attribute

Question

I´d like to count all images for one <div class="thumbnail"> separately.

My code:

    <div class="thumbnail">     

    <a rel="first" href="#">
        <div>
        <div></div>
        <img src="...">
        </div>
    </a>

    <div class="hidden-fb"> <!-- // CSS display: none -->                                                                                                 
        <a rel="first" href="#">
            <div>
            <div></div>
            <img src="...">
            </div>
        </a>                                               
    </div><!-- .hidden-fb -->

</div><!-- .thumbnail -->

<h2>Contains 2* images </h2>

I try this

var featureImageCount = $('div.thumbnail img').length;    
$('div.thumbnail').after('<div><h1>' + featureImageCount + ' Images</h1></div>');

But I get just for all divs "(6)"
Can I do this with jquery, that the number* of images will be automatically fill out?
Or can jquery count the items by different rel attributes?

jsFiddle

Thanks

Answer 1

$('div.thumbnail').each(function () {

    var $this = $(this),
        count = $this.find('img').length;

    $this.after('<h2>', {
        text: 'Contains (' + count  + '*) image' + (count == 1 ? '' : 's')
    });

});

You need to look at each .thumbnail element individually, using .each. Then, you can use $(this) in the callback to access the actual element. From there, you can find all specific descendent <img> elements. From there, you can just use .after like you attempt to, with $(this).

$(document).ready(function () {
    $("div.thumbnail").each(function () {
        var $this = $(this),
            count = $this.children("a").children("img").length;
        $this.after("<div><h1>" + count + " Images</h1></div>");
    });
});
