javascript - 从div中获取类名

Question

我想检索 .find_class 中最后一个子元素的类名(class last div new3)，但我的代码给了我类 select3。我该如何修复它？

演示: http://jsfiddle.net/gBxan/5/

<div class="find_class mediumCell">
    <div class="new1 old1">
        <div class="select1"></div>
    </div>
    <div class="new2 old2">
        <div class="select2"></div>
    </div>
    <div class="new3 old3"><!-- I want to get this div's class name 'new3' -->
        <div class="select3"></div>
    </div>
</div>

var find = $('div.find_class div:last').attr('class');
alert(find);

Answer 1

使用子选择器(>):

var find = $('div.find_class > div:last').attr('class');
