闲着没事,随便写了个简单的JavaScript tabel切换,大家有兴趣的看看,有需要的就拿去吧.废话不说了,大家看代码吧
方法一：for循环+if判断当前点击与自定义数组是否匹配
<!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">
//定义数组并获取数组内各个的节点
var buttonArr = document.getElementsByTagName("button");
var divArr = document.getElementsByTagName("div");
for(var i = 0; i < buttonArr.length;i++) {
buttonArr[i].onclick = function() {
//this
// alert(this.innerHTML)
//for循环遍历button数组长度
for(var j = 0; j < buttonArr.length; j++) {
//重置所有的button样式
buttonArr[j].style.backgroundColor = "#ccc";
//给当前的(点击的那个)那个button添加样式
this.style.backgroundColor = "yellow";
//隐藏所有的div
divArr[j].style.display = "none";
//判断当前点击是按钮数组中的哪一个？
if(this == buttonArr[j]) {
// alert(j);
//显示点击按钮对应的div
divArr[j].style.display = "block";
}
}
}
}
</script>
</body>
</html>
方法二：自定义index为当前点击
<!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>
方法三：className
<!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>
方法四：className+匿名函数的自执行！
<!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++) {
(function(i){ //匿名函数自执行
buttonList[i].onclick = function() {
for(var j = 0; j < buttonList.length;j++) {
buttonList[j].className = "";
divList[j].className = "";
}
this.className = "btn-active";
divList[i].className = "div-active";
}
})(i)
}
</script>
</body>
</html>
