角度控制器未注册错误

I am new to Angular JS and I am using the 1.6 version of it.

我是Angular JS的新手，我正在使用它的1.6版本。

I have this apptest.js script:

我有这个apptest.js脚本：

var myApp = angular.module("myApp", []);

(function(){
    "use strict";
    myApp.controller("productController", function($scope, $http)

    {
        $http.get('data/data.json').then(function(prd)
        {
            $scope.prd = prd.data;
        });
    });
});

And here my data/data.json data:

在这里我的data / data.json数据：

[
  {
    "id":"1",
    "title":"20 Foot Equipment Trailer",
    "description":"2013 rainbow trailer 20 feet x 82 inch deck area, two 5,000 lb axels, electric brakes, two pull out ramps, break away box, spare tire.",
    "price":6000,
    "posted":"2015-10-24",
    "contact": {
      "name":"John Doe",
      "phone":"(555) 555-5555",
      "email":"johndoe@gmail.com"
    },
    "categories":[
      "Vehicles",
      "Parts and Accessories"
    ],
    "image": "http://www.louisianasportsman.com/classifieds/pics/p1358549934434943.jpg",
    "views":213
  }
]

Now here is my html page where I specified the ng-app and ng-controller:

现在这是我的html页面，我在其中指定了ng-app和ng-controller：

<body ng-app="myApp" ng-controller="productController">
<div class="row">
    <nav class="navbar navbar-default">
      <div class="container-fluid">
        <!-- Brand and toggle get grouped for better mobile display -->
        <div class="navbar-header">
          <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
          </button>
          <a class="navbar-brand" href="#">Brand</a>
        </div>

        <!-- Collect the nav links, forms, and other content for toggling -->
        <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
          <ul class="nav navbar-nav">
            <li class="active"><a href="#">Add <span class="sr-only">(current)</span></a></li>
          </ul>
          <form class="navbar-form navbar-left">
            <div class="form-group">
              <input type="text" class="form-control" placeholder="Search">
            </div>
            <button type="submit" class="btn btn-default">Submit</button>
          </form>
        </div><!-- /.navbar-collapse -->
      </div><!-- /.container-fluid -->
    </nav>

    <div class="col-sm-4" ng-repeat="product in prd">
        <div class="panel panel-primary">
            <div class="panel-heading">{{product.title}}</div>
            <div class="panel-body">
                <img ng-src="{{product.image}}">
                {{product.price | currency}}
                {{product.description}}
            </div>
            <div class="panel-footer">a</div>
        </div>
    </div>
</div>

<script src="angular/angular.js"></script>
<script src="scripts/appTest.js"></script>
</body>

I am still getting the following error which is new for me:

我仍然收到以下错误，这对我来说是新的：

angular.js:14239 Error: [$controller:ctrlreg] The controller with the name 'productController' is not registered. http://errors.angularjs.org/1.6.0-rc.0/$controller/ctrlreg?p0=productController

angular.js：14239错误：[$ controller：ctrlreg]名称为“productController”的控制器未注册。 http://errors.angularjs.org/1.6.0-rc.0/$controller/ctrlreg?p0=productController

Any help is appreciated.

Its because of your Immediately Invoked Function Expression. you have to change it like below :

因为你的立即调用函数表达式。你必须改变它如下：

var myApp = angular.module("myApp", []);

(function(app){
  "use strict";
  app.controller("productController", function($scope, $http){
    $http.get('data/data.json').then(function(prd){
      $scope.prd = prd.data;
    });
  });
})(myApp);

i import the file, in index.html and my problem solved,

我在index.html导入文件，我的问题解决了，

<script src=".../productController.js"></script>

#3

In my case, it was missing reference in index page as well as my controller name was startupController (notice lower case s) and I was trying to register it with StartupController (upper case s)

在我的情况下，它在索引页面中缺少引用以及我的控制器名称是startupController（注意小写s），我试图用StartupController注册它（大写s）

#4

In my case, with this same error, I failed to identify the app module in the ng-app directive like this:

在我的情况下，由于同样的错误，我无法在ng-app指令中识别app模块，如下所示：

<div class="row" ng-app>

In some circumstances I've seen where ng-app is by itself but I was forced to identify the app like:

在某些情况下，我已经看到ng-app本身就在哪里，但我*识别应用程序，如：

<div class="row" ng-app="myApp">

-1

This error occurs when the $controller() service is called with a string that does not match any of the registered controllers. The controller service may have been invoked directly, or indirectly, for example through the ngController directive, or inside a component / directive / route definition (when using a string for the controller property). Third-party modules can also instantiate controllers with the $controller() service

使用与任何已注册的控制器不匹配的字符串调用$ controller（）服务时，会发生此错误。控制器服务可能已直接或间接调用，例如通过ngController指令，或在组件/指令/路由定义内（当使用字符串作为控制器属性时）。第三方模块还可以使用$ controller（）服务实例化控制器

Causes for this error can be:

导致此错误的原因可能是：

1- Your reference to the controller has a typo. For example, in the ngController directive attribute, in a component definition's controller property, or in the call to $controller().

1-您对控制器的引用有拼写错误。例如，在ngController指令属性中，在组件定义的控制器属性中，或在对$ controller（）的调用中。

2- You have not registered the controller (neither via Module.controller nor $controllerProvider.register().

2-您尚未注册控制器（既不通过Module.controller也不通过$ controllerProvider.register（）。

3- You have a typo in the registered controller name.

3-注册的控制器名称中有拼写错误。
