我想为特定类的所有秒元素绑定一个点击事件，我正在使用；

$("ul.message-list-row > li:eq(1) > div").click(function(){...});

不幸的是，它不起作用。我也试过没有“>”但没有运气。

我的代码中有 7 个相同的 UL。所以，

console.log($("ul.message-list-row").length);

返回 7，但是

console.log($("ul.message-list-row > li:eq(1)").length);

返回 1。不应该是 7 吗？错误是什么？

顺便说一句，我正在尝试使用以下标记；

<ul class="message-list-row rounded-corners">
    <li>
        <img src="Public/CSS/Images/sample-app-icon-02.png" alt="" title="" />

:eq()不像你想象的那样工作。使用:nth-child(2)而不是:eq(1).

:nth-child选择器获取 jQuery 集合中作为其父级的第 n 个子级的每个元素。选择:eq器只获取 jQuery 集合中的一个元素，即“第 n 个”（0 索引）元素。
