JavaScript,tab,切换本文实例讲解了JavaScript实现简单的tab选项卡切换的示例代码，分享给大家供大家参考，具体内容如下 效果图： 
具体代码： <!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>table切换</title> <style type="text/css"> *{ padding: } button{ width: 95px; } .active { background-color: yellow; } #wrap{ width:510px; overflow: hidden; margin:0 auto; } #inner{ width:9999px; overflow: hidden; position: relative; left:0; transition: left 0.6s; } #inner a { float: left; } #inner img { display: block; width:510px; } #main{ text-align: center; } </style></head><body> <div id="wrap"> <div id="inner"> <a href="###"><img src="img/1.jpg"></a> <a href="###"><img src="img/2.jpg"></a> <a href="###"><img src="img/3.jpg"></a> <a href="###"><img src="img/4.jpg"></a> <a href="###"><img src="img/5.jpg"></a> </div> </div> <div id="main"> <button>1</button> <button>2</button> <button>3</button> <button>4</button> <button>5</button> </div> <script type="text/javascript"> //获取节点 var btnList = document.getElementsByTagName("button"); var inner = document.getElementById("inner"); //可见宽度 var perWidth = inner.children[0].offsetWidth; //添加事件 for(var i = 0; i < btnList.length; i++) { btnList[i].index = i; btnList[i].onclick = function() { inner.style.left = -perWidth * this.index + "px"; for(var j = 0; j < btnList.length; j++) { btnList[j].className = ""; } this.className = "active"; } } </script></body></html>希望本文所述对大家学习javascript程序设计有所帮助，熟练掌握选项卡切换操作。
