問題解答
回答1：自己看看官網(wǎng)鏈接描述就曉得了，你這函數(shù)也沒調(diào)用啊
回答2：數(shù)據(jù)雙向綁定，在angular上教程上
回答3：例子<!DOCTYPE html><html><meta charset='utf-8'><script src='http://cdn.static.runoob.com/...
<body>
<p ng-app='myApp' ng-controller='myCtrl'>
名: <input type='text' ng-model='firstName'>姓: <input type='text' ng-model='lastName'>姓名: {{firstName + ' ' + lastName}}
</p>
<script>var app = angular.module(’myApp’, []);app.controller(’myCtrl’, function($scope) {
$scope.firstName = 'John';$scope.lastName = 'Doe';
});</script>
</body></html>
回答4：在你的html文檔中 ng-app 應(yīng)該賦值（和js中定義的相同），eg: ng-app='DemoApp'
