根据作用域表达式动态切换把那个DOM元素包含在已经编译的模板中。

示例代码：

<!DOCTYPE html>
<!--指定angular管理的范围-->
<html ng-app="app01">

    <head>
        <meta charset="UTF-8">
        <title>指令</title>
    </head>

    <body>
        <!--指定控制器的作用范围-->
        <form ng-controller="Controller1" name="form1" ng-init="color='orangered'">
            请输入颜色：<input ng-model="color" />
            <p ng-switch="color" ng-style="{'color':color}">
                <span ng-switch-when="red">红色</span>
                <span ng-switch-when="green">绿色</span>
                <span ng-switch-when="blue">蓝色</span>
                <span ng-switch-default>输入错误，请输入red,green,blue</span>
            </p>
        </form>
        <!--引入angularjs框架-->
        <script src="js/angular146/angular.min.js" type="text/javascript" charset="utf-8"></script>
        <script type="text/javascript">
            //定义模块，指定依赖项为空
            var app01 = angular.module("app01", []);
            //定义控制器，指定控制器的名称，$scope是全局对象
            app01.controller("Controller1", function($scope) {});
        </script>
    </body>

</html>

运行结果：
