整理4种实现tab选项卡的方式 by angular

选项卡一：
js方法

<!DOCTYPE html><html>    <head>        <meta charset="utf-8">        <style>            #div1 .active{                background:blue;            }            #div1 div{                width:200px;                height:200px;                background:gray;                border:1px solid black;                display:none;            }        </style>        <script>            window.onload=function (){                var oDiv=document.getElementById('div1');                var aBtn=oDiv.getElementsByTagName('input');                var aDiv=oDiv.getElementsByTagName('div');                for(var i=0;i<aBtn.length;i++){         //遍历div1中的按钮                    aBtn[i].index=i;            //给aBth[]添加自定义属性                    aBtn[i].onclick=function (){                        for(var i=0;i<aBtn.length;i++){ //遍历按钮，将class清除                            aBtn[i].className='';                            aDiv[i].style.display='none';                        }                        this.className='active';                        aDiv[this.index].style.display='block';                    }                }            }        </script>    </head>    <body>        <div id="div1">            <input class="active" type="button" value="选项1" />            <input type="button" value="选项2" />            <input type="button" value="选项3" />            <input type="button" value="选项4" />            <div style="display:block;">111</div>            <div>222</div>            <div>333</div>            <div>444</div>        </div>    </body></html>

选项卡二：
angularjs指令：

ng-class、ng-click、ng-if

<!DOCTYPE html><html lang="en"><head>    <meta charset="UTF-8">    <title>tab栏</title>    <style>        .active {            background-color: orange;        }    </style>    <script src="http://sandbox.runjs.cn/uploads/rs/376/pbcx3e1z/angular.min.js"></script></head><body ng-app="s1.app"><div>    <button ng-class="{ 'active' : data.current == 1 }" ng-click="actions.setCurrent(1)">张三</button>    <button ng-class="{ 'active' : data.current == 2 }" ng-click="actions.setCurrent(2)">李四</button>    <button ng-class="{ 'active' : data.current == 3 }" ng-click="actions.setCurrent(3)">王五</button></div><div>    <div ng-if="data.current == 1">张三的个人信息</div>    <div ng-if="data.current == 2">李四的个人信息</div>    <div ng-if="data.current == 3">王五的个人信息</div>    <script>        var app = angular.module('s1.app', []);        app.run(function ($rootScope) {            $rootScope.data = {                current: "1" // 1代表张三，2代表李四，3代表王五            };            $rootScope.actions =            {                setCurrent: function (param) {                    $rootScope.data.current = param;                }            }        })    </script></div></body></html>

选项卡三：
angularjs指令：

ng-class、ng-click、ng-show

<!DOCTYPE html><html ng-app="myApp"><head lang="en">    <meta charset="UTF-8">    <title></title>    <script src="https://cdn.static.runoob.com/libs/angular.js/1.4.6/angular.min.js"></script></head><body><section ng-controller="myCtrl as panel">    <ul>        <li ng-class="{active:panel.isSelected(1)}">            <a href ng-click="panel.selectTab(1)">1111111111</a>        </li>        <li ng-class="{active:panel.isSelected(2)}">            <a href ng-click="panel.selectTab(2)">2222222222</a>        </li>        <li ng-class="{active:panel.isSelected(3)}">            <a href ng-click="panel.selectTab(3)">33333333333</a>        </li>    </ul>    <!--是否点击-->    {{panel.isSelected(1)}}    {{panel.isSelected(2)}}    {{panel.isSelected(3)}}    <div class="panel" ng-show="panel.isSelected(1)">        <h1>我是1111111111111111111111</h1>    </div>    <div class="panel" ng-show="panel.isSelected(2)">        <h1>我是22222222222222222</h1>    </div>    <div class="panel" ng-show="panel.isSelected(3)">        <h1>我是3333333333333333333333</h1>    </div></section><script>    var app = angular.module("myApp", []);    app.controller("myCtrl", function () {        this.tab = 2;/*设置默认*/        this.selectTab = function (setTab) {/*设置tab点击事件*/            this.tab = setTab;        };        this.isSelected = function (checkedTab) {/*页面的切换*/            return this.tab === checkedTab;        }    });</script></body></html>

选项卡四：

angularjs 指令

第二种和第三种方式来源于下面代码的改进，产生的效果都是一样的。

<!DOCTYPE html><html ng-app="myApp"><head lang="en">    <meta charset="UTF-8">    <title></title>    <script src="https://cdn.static.runoob.com/libs/angular.js/1.4.6/angular.min.js"></script></head><body><section ng-init="tab=3">    <ul>        <li ng-class="{active:tab===1}">            <a href ng-click="tab=1">1111111111</a>        </li>        <li ng-class="{active:tab===2}">            <a href ng-click="tab=2">2222222222</a>        </li>        <li ng-class="{active:tab===3}">            <a href ng-click="tab=3">33333333333</a>        </li>    </ul>    <!--是否点击-->    {{tab===1}}    {{tab===2}}    {{tab===3}}    <div class="panel" ng-show="tab===1">        <h1>我是1111111111111111111111</h1>    </div>    <div class="panel" ng-show="tab===2">        <h1>我是22222222222222222</h1>    </div>    <div class="panel" ng-if="tab===3">        <h1>我是3333333333333333333333</h1>    </div></section><script>    var app = angular.module("myApp", []);    app.controller("myCtrl", function () {    });</script></body></html>
