如何实现vhtml选项卡切换内容？
1、三个DIV形成的版块只会显示第三个汽车的内容。
二、制作过程
1、 制作HTML结构框架
2、完成对应CSS的输入，使页面形成特定布局
<!DOCTYPE html>
<html lang="en">
<head> <meta charset="UTF-8"> <title>tab切换</title> <style type="text/css"> button { width:120px; height: 32px; line-height: 32px; background-color: #ccc; font-size: 24px; } div { display: none; width:200px; height: 200px; font-size: 72px; color:#ddd; background-color: green; border:1px solid black; } </style> </head> <body> <button style="background-color: yellow;">1</button> <button>2</button> <button>3</button> <button>4</button> <div style="display:block;">1</div> <div>2</div> <div>3</div> <div>4</div> <script type="text/javascript"> var buttonArr = document.getElementsByTagName("button"); var divArr = document.getElementsByTagName("div"); for(var i = 0; i < buttonArr.length;i++) { buttonArr[i].index = i; // buttonArr[i].setAttribute("index",i); buttonArr[i].onclick = function() { for(var j = 0; j < buttonArr.length; j++) { buttonArr[j].style.backgroundColor = "#ccc"; buttonArr[this.index].style.backgroundColor = "yellow"; divArr[j].style.display = "none"; divArr[this.index].style.display = "block"; } } } </script> </body> </html>
3、输写javascript代码，对选项卡标头分别注册相应的事件
<!doctype html> <html lang="en"> <head> <meta charset="UTF-8"> <title>tab</title> <style type="text/css"> * {padding:0; margin:0;} button { background-color: #ccc; width:80px; height: 30px; } .btn-active { background-color: yellow; font-weight:bold; font-size: 14px; } div{ width:200px; height: 200px; font-size: 64px; background-color: #0c0; display: none; color:#fff; } .div-active { display: block; } </style> </head> <body> <button class="btn-active">按钮1</button> <button>按钮2</button> <button>按钮3</button> <button>按钮4</button> <div class="div-active">1</div> <div>2</div> <div>3</div> <div>4</div> <script type="text/javascript"> //1.先获取元素 var buttonList = document.getElementsByTagName("button"); var divList = document.getElementsByTagName("div"); //2.添加事件 for(var i = 0; i < buttonList.length; i++) { buttonList[i].index = i; buttonList[i].onclick = function() { for(var j = 0; j < buttonList.length;j++) { buttonList[j].className = ""; divList[j].className = ""; } this.className = "btn-active"; divList[this.index].className = "div-active"; } } </script> </body> </html>
4、完整代码：
<!DOCTYPE html><html><head lang="en"> <meta charset="UTF-8"> <title> 选项卡</title> <style type="text/css"> /* CSS样式制作 */ *{padding:0px; margin:0px;} a{ text-decoration:none; color:black;} a:hover{text-decoration:none; color:#336699;} #tab{width:270px; padding:5px;height:150px;margin:20px;} #tab ul{list-style:none; display:;height:30px;line-height:30px; border-bottom:2px #C88 solid;} #tab ul li{background:#FFF;cursor:pointer;float:left;list-style:none height:29px; line-height:29px;padding:0px 10px; margin:0px 10px; border:1px solid #BBB; border-bottom:2px solid #C88;} #tab ul li.on{border-top:2px solid Saddlebrown; border-bottom:2px solid #FFF;} #tab div{height:100px;width:250px; line-height:24px;border-top:none; padding:1px; border:1px solid #336699;padding:10px;} .hide{display:none;} </style> <script type="text/javascript"> // JS实现选项卡切换 window.onload = function(){ var myTab = document.getElementById("tab"); //整个div var myUl = myTab.getElementsByTagName("ul")[0];//一个节点 var myLi = myUl.getElementsByTagName("li"); //数组 var myDiv = myTab.getElementsByTagName("div"); //数组 for(var i = 0; i<myLi.length;i++){ myLi[i].index = i; myLi[i].onclick = function(){ for(var j = 0; j < myLi.length; j++){ myLi[j].className="off"; myDiv[j].className = "hide"; } this.className = "on"; myDiv[this.index].className = "show"; } } } </script></head><body><!-- HTML页面布局 --><div id = "tab"> <ul> <li class="off">房产</li> <li class="on">家居</li> <li class="off">二手房</li> </ul> <div id="firstPage" class="hide"> <a href = "#">切换代码tab</a> <a href = "#">切换代码tab</a> <a href = "#">切换代码tab/a> <a href = "#">切换代码tab</a> </div> <div id="secondPage" class="show"> <a href = "#">切换代码tab</a> <a href = "#">切换代码tab</a> <a href = "#">切换代码tab</a> <a href = "#">切换代码tab</a> </div> <div id="thirdPage" class = "hide"> <a href = "#">切换代码tab</a> <a href = "#">切换代码tab</a> <a href = "#">切换代码tab</a> <a href = "#">切换代码tab</a> </div></div></body></html>

$(function(){
$(".lanrenzhijia .tab a").mouseover(function(){
