Question

我正在做一个Angularjs课程，我必须做一个练习，但对我来说这样做是不可能的：

app.js：

function OcultarController($scope) {
  $scope.oculto = true;

  $scope.cambioColor = function() {
    $scope.oculto = !$scope.oculto;
  };
}

angular.module('app', []);
angular.module('myModule').config(['$controllerProvider', function($controllerProvider) {
  $controllerProvider.allowGlobals();
}]);

的index.html

<html ng-app="app">
  <head>
    <meta charset="utf-8">
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
    <script src="app.js"></script>
  </head>

  <body>
    <div ng-controller="OcultarController">
      <p style="background-color:red;" ng-show="oculto">ROJO</p>
      <p style="background-color:green;" ng-hide="oculto">VERDE</p>
      <button ng-click="cambioColor()">Cambiar color</button>
    </div>
  </body>
</html>

我试着让它工作，但我不能，我是Angularjs的新手，我不知道我是否做得好，这个练习只是告诉我复制过去的代码，但是什么我觉得并不那么容易。

控制台告诉我这个（我正在使用firefox）：

Answer 1

首先，你在这里创建两个模块（这不一定是个问题，但在你的情况下，我猜你不需要那个）：

angular.module('app', []);
angular.module('myModule').

将其更改为：

var app = angular.module('app', []);
app.config(['$controllerProvider', function($controllerProvider) {
  $controllerProvider.allowGlobals();
}]);

app.controller('OcultarController', OcultarController);

Answer 2

你必须告诉你的应用程序＆＃34;它应该加载你的模块＆＃34; myModule＆＃34;。

更改

/Volumes/HD/Repos

到

angular.module('app', []);

并将其移至文件的末尾。

$dbh->do("LISTEN abc");
$dbh->do("LISTEN def");

## Hang around until we get the message we want
LISTENLOOP: {
  while (my $notify = $dbh->pg_notifies) {
    my ($name, $pid, $payload) = @$notify;
    print qq{I received notice "$name" from PID $pid, payload was "$payload"\n};
    ## Do something based on the notice received
  }
  $dbh->ping() or die qq{Ping failed!};
  $dbh->commit();
  sleep(5);
  redo;
}

角度误差：[$ injector：modulerr]全局控制器
