jQuery 节点的查询_html/css_WEB-ITnose
<a id = 1>XX</a><ul><li>xx</li><li>xx</li><li>xx</li><li>xx</li></ul><a id = 2>XX</a><ul><li>xx</li><li>xx</li><li>xx</li><li>xx</li></ul><a id = 3>XX</a><ul><li>xx</li><li>xx</li><li>xx</li><li>xx</li></ul>
------------------------jQuery代码如上面
回复讨论(解决方案)
如上所示 点击某一个
$("li").click(function(event){ alert($(this).parent().prev().attr("id"));});
$("li").click(function(event){ alert($(this).parent().prev().attr("id"));});
$("li").click(function(event){ alert($(this).parent().prev().attr("id"));});<html><head> <title>test</title> <script src="http://jquery.cuishifeng.cn/js/jquery-2.1.4.min.js?v=20160120"></script></head><body><a id = '1'>XX</a><ul><li>xx</li><li>xx</li><li>xx</li><li>xx</li></ul><a id = '2'>XX</a><ul><li>xx</li><li>xx</li><li>xx</li><li>xx</li></ul><a id = '3'>XX</a><ul><li>xx</li><li>xx</li><li>xx</li><li>xx</li></ul><script>$("li").click(function(event){ alert($(this).parent().prev().attr("id"));});</script></body></html>引入jquery，并且你的dom结构写正确
$("li").click(function(event){ alert($(this).parents("a").attr("id"));});这样呢？
引入jar包，js区域写上
$(function(){
$("li").click(function(event){
alert($(this).parent().prev().attr("id"));
});
})
<p class="yy"> 引入jar包，js区域写上$(function(){ $("li").click(function(event){ alert($(this).parent().prev().attr("id")); });}) </p>也不可以。。无法获取 我贴部分源码。
<h3 id="a-nbsp-id-nbsp-nbsp-XX-a"><a id = '1'>XX</a></h3><ul><li>xx</li><li>xx</li><li>xx</li><li>xx</li></ul><h3 id="a-nbsp-id-nbsp-nbsp-XX-a"><a id = '2'>XX</a></h3><ul><li>xx</li><li>xx</li><li>xx</li><li>xx</li></ul><h3 id="a-nbsp-id-nbsp-nbsp-XX-a"><a id = '3'>XX</a></h3><ul><li>xx</li><li>xx</li><li>xx</li><li>xx</li></ul>$.ajax({xxxxxxsuccess:function(){ $("ul li:last-child").bind("click", Addhut);}}); function Addhut() { // parId = $(this).parent().filter("a").attr("id"); parId = $(this).parent("a").prev().attr("id"); alert(parId);}具体结构就是这样，页面载入时执行ajax函数，成功后执行回调函数。最后一个li标签绑定Addhut函数 点击后 获得上面的的id
跪求大神答疑解惑！
你检查你的事件，我们给你的基本都可以

为什么我的 一直提示 undefined

你的bind的格式不对，这是点击每项的最后一个弹出提示

不客气，不懂的可以多百度，查api，问别人是最后的手段
