#与其他语言 switch case对比
- switch -->ng-switch --选择变量
- case->ng-switch-when --选择匹配的值
示例如下：
<body ng-app="myApp" ng-controller="demoCtrl">
<!--
匹配上 显示 匹配不上 隐藏
-->
<div ng-switch="num">
<button ng-click="num=1">按钮1</button>
<button ng-click="num=2">按钮2</button>
<button ng-click="num=3">按钮3</button>
<div ng-switch-when="1">按钮1对应的内容</div>
<div ng-switch-when="2">按钮2对应的内容</div>
<div ng-switch-when="3">按钮3对应的内容</div>
</div>
<script src="node_modules/angular/angular.js"></script>
<script>
angular.module('myApp',[])
.controller('demoCtrl',['$scope',function($scope){
$scope.num = 1;
}])
</script>
</body>
