Question

所以我在学习JSAngular中的指令和控制器。目前我只是想让开胃菜在菜单上循环，但似乎无法让输出响应。我在这里错过了什么？提前谢谢。

MainController.js：

app.controller('MainController', ['$scope', function($scope) {
  $scope.today = new Date();

  $scope.appetizers = [
    {
      name: 'Caprese',
      description: 'Mozzarella, tomatoes, basil, balsmaic glaze.',
      price: 4.95
    },
    {
      name: 'Bruschetta',
      description: 'Grilled bread garlic, tomatoes, olive oil.',
      price: 4.95
    },
    {
      name: 'Mozzarella Sticks',
      description: 'Served with marinara sauce.',
      price: 3.95
    }
  ];

  $scope.mains = [
    {
      name: 'Roast Beef Au Jus',
      description: 'Delicious Amazing Sauce',
      price: 15.99
    },
    {
      name: 'Prime Rib',
      description: 'Just like Jacoby/s',
      price: 18.95
    },
    {
      name: 'BBQ Ribs',
      description: 'Better than Krupa/s',
      price: 15.99
    }
  ]

  $scope.extras = [
    {
      name: 'Cole slaw',
    },
    {
      name: 'Creamed Spinach',
    },
    {
      name: 'Boston Baked Beans',
    }
  ]

}]);

您需要先参考您的$ ./sbt/sbt assembly Invoking 'build/sbt assembly' now [info] Loading project definition... [warn] Multiple resolvers having different access mechanism configured with same name 'sbt-plugin-releases'. ... [info] Resolving org.eclipse.jetty#jetty-parent;18 [error] Server access Error: Connection reset url=http://download.eclipse.org/jgit/maven/org/eclipse/jetty/jetty-parent/18/jetty-parent-18.jar [error] Server access Error: Server redirected too many times (20) url=http://scalasbt.artifactoryonline.com/scalasbt/sbt-plugin-releases/org.eclipse.jetty.orbit/jetty-orbit/1/jars/jetty-orbit.jar申请模块。在创建控制器之前添加以下代码行。

String query ="SELECT * FROM table_name WHERE username=username_value & password=password_value";

Cursor  cursor = database.rawQuery(query,null);

    if (cursor != null) {
        // success
    }else{
   //   fail
}

这是指您要创建控制器的应用程序，并包含您的应用所依赖的模块列表。

在您的情况下，列表为空。

为什么我的jsangular不在我的范围内循环？
