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="/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./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./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>
