本文实例讲述了JS实现的简单标签点击切换功能。分享给大家供大家参考,具体如下:
先来看看运行效果:
具体代码如下:
<!DOCTYPE html> <html> <head lang="en"> <meta charset="UTF-8"> <title>www.jb51.net </title> <style> * { margin: 0; padding: 0; } ul { list-style-type: none; } .box { width: 400px; height: 300px; border: 1px solid #ccc; margin: 100px auto; overflow: hidden; } .hd { height: 45px; } .hd span { display: inline-block; width: 90px; background-color: pink; line-height: 45px; text-align: center; cursor: pointer; } .hd span.current { background-color: yellowgreen; } .bd li { height: 255px; background-color: yellowgreen; display: none; } .bd li.current { display: block; font-size: 36px; } </style> </head> <body> <div class="box" id="box"> <div class="hd"> <span class="current">体育</span> <span>娱乐</span> <span>新闻</span> <span>综合</span> </div> <div class="bd"> <ul> <li class="current">我是体育模块</li> <li>我是娱乐模块</li> <li>我是新闻模块</li> <li>我是综合模块</li> </ul> </div> </div> <script> var box = document.getElementById("box"); var spans = box.getElementsByTagName("span"); var lis = box.getElementsByTagName("li"); for (var i = 0; i < spans.length; i++) { spans[i].aaa = i; spans[i].onclick = function () { for (var i = 0; i < spans.length; i++) { spans[i].className = ""; lis[i].className = ""; } this.className = "current"; lis[this.aaa].className = "current"; } } </script> </body> </html>
