同一文件中有多个应用和控制器

angularjs

在此AngularJS代码中:

<!DOCTYPE html>
<html>
<head>
  <script src="http://code.angularjs.org/1.2.9/angular.min.js" type="text/javascript"></script>
  <script>
    var app1 = angular.module('app1', []);

    app1.controller('Ctrl1', function ($scope)
    {
      $scope.name = "Jack";
    });

    var app2 = angular.module('app2', []);

    app2.controller('Ctrl2', function ($scope)
    {
      $scope.name = "Steve";
    });

  </script>
  <title>Test Controllers</title>
</head>
<body>
  <div ng-app="app1">
    <div ng-controller="Ctrl1">
      <span>{{name}}</span>
    </div>
  </div>
  <div ng-app="app2">
    <div ng-controller="Ctrl2">
      <span>{{name}}</span>
    </div>
  </div>
</body>
</html>

我有两个ng-app和两个控制器。但是似乎只有第一个有效。显示了姓名Jack,但没有显示Steve。为什么?

ng-
app指令的自动初始化仅发生一次,但是您可以使用bootstrapping方法手动初始化其他模块。(请参阅:https
:
//docs.angularjs.org/guide/bootstrap)

带有解决方案的JSFiddle在这里:http :

<!DOCTYPE html>
<html>
<head>
  <script src="http://code.angularjs.org/1.2.9/angular.min.js" type="text/javascript"></script>
  <script>
    var app1 = angular.module('app1', []);

    app1.controller('Ctrl1', function ($scope)
    {
      $scope.name = "Jack";
    });

    var app2 = angular.module('app2', []);

    app2.controller('Ctrl2', function ($scope)
    {
      $scope.name = "Steve";
    });

    angular.element(document).ready(function() {
      angular.bootstrap(document.getElementById('app2'), ['app2']);
    });   
  </script>
  <title>Test Controllers</title>
</head>
<body>
  <div ng-app="app1">
    <div ng-controller="Ctrl1">
      <span>{{name}}</span>
    </div>
  </div>
  <div id="app2">
    <div ng-controller="Ctrl2">
      <span>{{name}}</span>
    </div>
  </div>
</body>
</html>
