角度控制器未注册错误
角度控制器未注册错误
提问于 2016-11-21 20:55:08
我是Angular JS的新手，我正在使用它的1.6版本。
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;
});
});
});下面是我的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
}
]下面是我指定ng-app和ng-controller的html页面：
<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>我仍然收到以下错误，这对我来说是新的：
angular.js:14239错误：$controller:ctrlreg名为'productController‘的控制器未注册。http://errors.angularjs.org/1.6.0-rc.0/$controller/ctrlreg?p0=productController
任何帮助都是非常感谢的。

这是因为你的Immediately Invoked Function Expression。你必须像下面这样修改它：
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);Stack Overflow用户

只需将文件导入index.html即可，
<script src=".../productController.js"></script>Stack Overflow用户

在我的例子中，它在索引页中缺少引用，而且我的控制器名称是startupController (注意小写的s)，我试图用StartupController注册它(大写的s)。
