我们准备一个TAB导航#pagenavi，里面包含TAB导航要切换的四个导航按钮，然后是切换的主体内容#slider，这里应该放置四个li与导航按钮对应，内容自定义。
由于是移动端应用，我们加载zepto.js，zepto就是体积小的jquery。然后需要加载触屏滑动插件touchslider.js。
接下来我们就直接调用TouchSlider，通过设置绑定tab，滑动方向、速度、时间等信息实现内容切换，请看详细代码：
<script type="text/javascript">
var page='pagenavi'
var mslide='slider'
var mtitle='emtitle'
arrdiv = 'arrdiv'
var as=document.getElementById(page).getElementsByTagName('a')
var tt=new TouchSlider({id:mslide,'auto':'-1',fx:'ease-out',direction:'left',speed:600,timeout:5000,'before':function(index){
var as=document.getElementById(this.page).getElementsByTagName('a')
as[this.p].className=''
as[index].className='active'
this.p=index
var txt=as[index].innerText
$("#"+this.page).parent().find('.emtitle').text(txt)
var txturl=as[index].getAttribute('href')
var turl=txturl.split('#')
$("#"+this.page).parent().find('.go_btn').attr('href',turl[1])
}})
tt.page = page
tt.p = 0
for(var i=0i<as.lengthi++){
(function(){
var j=i
as[j].tt = tt
as[j].onclick=function(){
this.tt.slide(j)
return false
}
})()
}
</script>
html 选项卡切换内容方法：
工具/原料
网页编辑器dreamweaver
javascript中的getElementById和getElementsByTagName方法
操作步骤：
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.lengthi++) {
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.lengthj++) {
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">

</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.lengthi++){
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">
