角度控制器未注册错误 [英] Angular controller is not registered error
问题描述
我是Angular JS的新手，正在使用1.6版本.
I am new to Angular JS and I am using the 1.6 version of it.
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;
});
});
});
这是我的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
}
]
现在这是我指定ng-app和ng-controller的html页面:
Now here is my html page where I specified the ng-app and 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>
我仍然遇到以下错误，这对我来说是新的:
I am still getting the following error which is new for me:
angular.js:14239错误:[$ controller:ctrlreg]带有 名称'productController'未注册. http://errors.angularjs.org/1.6.0-rc.0/ $ controller/ctrlreg?p0 = productController
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
感谢您的帮助.
推荐答案
这是因为您的Immediately Invoked Function Expression.您必须像下面这样更改它:
Its because of your Immediately Invoked Function Expression. you have to change it like below :
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);
