https://code.angularjs.org/
3.模块内引用 angularjs

2.复合表达式
<body ng-app ng-init="obj={id:'1521',name:'oracle'}"> {{'id是：'+obj.id}}<br> {{'name是：'+obj.name}}<br> </body>
<body ng-app ng-init="obj=[{port:'1521',name:'oracle'},{id:'80',name:'http'}]"> {{'1521端口号代表：'+obj[0].name}}<br> {{'http端口号为：'+obj[1].id}}<br> </body>
3.双向绑定
<body> <div ng-app> <p>名字 : <input type="text" ng-model="name"></p> <h1>Hello {{name}}</h1> </div> </body>
