$(this).html(); 输出的内容有点疑惑,求解~谢过_html/css_WEB-ITnose
<html><head></head> <script src="__PUBLIC__/Js/jquery-1.8.3.min.js"></script> <script> $(document).ready(function(){ $("#menu_id ul ul").css("display","block"); $("#menu_id ul li").click(function(){ console.log($(this).html()); }); }); </script><body> <div style="position:relative; overflow:auto;" id="menu_id"> <ul> <!-- 第一个:Li --> <li> <span>gaga</span> <ul> <li> ABCD <ul> <li><a href="#">a</a></li> <li><a href="#">a</a></li> <li><a href="#">a</a></li> <li><a href="#">a</a></li> <li><a href="#">a</a></li> </ul> </li> <li> <span>ABCD</span> <ul> <li><a href="#">b</a></li> <li><a href="#">b</a></li> <li><a href="#">b</a></li> <li><a href="#">b</a></li> <li><a href="#">b</a></li> </ul> </li> <li> <span>ABCD</span> <ul> <li><a href="#">c</a></li> <li><a href="#">c</a></li> <li><a href="#">c</a></li> <li><a href="#">c</a></li> <li><a href="#">c</a></li> </ul> </li> <li> <span>ABCD</span> <ul> <li><a href="#">d</a></li> <li><a href="#">d</a></li> <li><a href="#">d</a></li> <li><a href="#">d</a></li> <li><a href="#">d</a></li> </ul> </li> </ul> </li> </ul> </div></body></html>
我点击Li后输出的不止是当前的元素下的Html()输出了,还有根节点的Li的Html()也输出了,为什么啊?给个合理的解释,采纳给分哦,么么哒
回复讨论(解决方案)
因为事件会向上冒泡的
.
$(document).ready(function(){ $("#menu_id ul ul").css("display","block"); $("#menu_id ul li").click(function(event){ console.log($(this).html()); event.stopPropagation(); }); });
$("#menu_id ul") 下面有两个li嘛,首先打印里面li的内容 然后是外面的li的内容。 要是想打印最里层的那你不如再加个id
谢两位,问题解决,么么哒

The roles of HTML, CSS and JavaScript in web development are: 1. HTML defines the web page structure, 2. CSS controls the web page style, and 3. JavaScript adds dynamic behavior. Together, they build the framework, aesthetics and interactivity of modern websites.

The future trends of HTML are semantics and web components, the future trends of CSS are CSS-in-JS and CSSHoudini, and the future trends of JavaScript are WebAssembly and Serverless. 1. HTML semantics improve accessibility and SEO effects, and Web components improve development efficiency, but attention should be paid to browser compatibility. 2. CSS-in-JS enhances style management flexibility but may increase file size. CSSHoudini allows direct operation of CSS rendering. 3.WebAssembly optimizes browser application performance but has a steep learning curve, and Serverless simplifies development but requires optimization of cold start problems.
