Question

您好我已经开始学习Angular.js了，这是我的第一个活动。这一切都很好但是当我将ng-controller添加到body元素时它不起作用。我被困在这里你能告诉我这里有什么问题吗？

<html ng-app="helloWorldApp">

<head>
    <title>Angular Fundamentals</title>
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" integrity="sha384-1q8mTJOASx8j1Au+a5WDVnPi2lkFfwwEAa8hDDdjZlpLegxhjVME1fgjWPGmkzs7"
        crossorigin="anonymous">
</head>

<body ng-controller="firstController">
    <div class="container">
        <h1>AngularFundamentals</h1>
      <h2> {{'Hello World from Angular'}}</h2>
    </div>

  <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular.min.js"></script>
  <script>
  var helloWorldApp = angular.module('helloWorldApp',[]);
    helloWorldApp.controller('firstController',[ '$scope', function(scope){
      $scope.appName =" An App Name";

    }]);
  </script>
  </body>
</html>

Answer 1

你需要

 <h2>{{appName}}</h2>

<强>样本

  var helloWorldApp = angular.module('helloWorldApp',[]);
 helloWorldApp.controller('firstController',['$scope', function($scope){
      $scope.appName =" An App Name";

 }]);

＆＃13;

<html ng-app="helloWorldApp">
<head>
<body ng-controller="firstController">
    <div class="container">
        <h1>AngularFundamentals</h1>
      <h2> {{appName}}</h2>
    </div>

  <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular.min.js"></script>
