如果子元素中的类使用jQuery返回true

Question

<div id="media">
    <div id="table-pane">
        <img src="..." class="img-thumbnail">
        <img src="..." class="img-thumbnail selected">
        <img src="..." class="img-thumbnail">
    </div>
</div>

我想如果在子元素中选择了类返回true。我的代码

 $("#media").hasClass('.selected');

总是返回false ???

Answer 1

$(function(){
            if($('#media').children().children().hasClass('selected')){
                alert('class was found');
            }else{
                alert('class was not found');
            }

        })
