问题描述
当一个错误AngularJS崩溃参数MyCtrl不是一个函数,得到了不确定这可能是有点挑战性找到一个原因。
下面我想打一个样的检查表中,你该怎么检查时,得到一个错误
- 是与'MyCtrl通过HTML连接文件? (如果你Concat的两次检查或丑化您的文件)
<脚本的src ='路径/要/ controllers.js'>< / SCRIPT>
有一些图案:
app.controller('MyCtrl',['$范围',函数($范围内){...}] )app.controller('MyCtrl',函数($范围内){...})VAR MyCtrl =功能($范围内){...})
angular.module('应用',['app.sources']);
如果你定义的模块的多个次,你应该在这个顺序定义它
- 首先定义应该是这样
angular.module('app.sources',[]);
(是 []
)
- 随后定义应该是这样
angular.module('app.sources');
(不含 []
)
重要提示:声明顺序是非常重要的 - 与定义的 []
应先走
你可能已经忘记了复制粘贴后重命名模块。检查SRC像串
angular.module('app.sources',[]);
检查 'NG-应用
。最好只使用其中的一个与名称,如 NG-应用='应用'
(换句话说不定义多个无名ngApp指令)
是您的控制器的语法的为您正确AngularJS版本?
(有角中的 1.0.x的和 1.2.x版本及更高版本。具有角版本比 1.3.x的更大,你不能声明一个全局的构造函数和NG-控制器使用)
When AngularJS crashes with an error "Argument 'MyCtrl' is not a function, got undefined" it's may be little bit challenging to find a reason why.
Here I want to make a kind of a "check list", what should you check when got an error
- Is file with 'MyCtrl' connected via html? (check twice if you concat or uglify your files)
<script src='path/to/controllers.js'></script>
- Is 'MyCtrl' defined correctly?
There are a few patterns:
app.controller('MyCtrl', ['$scope', function ($scope) {...}])
app.controller('MyCtrl', function ($scope) {...})
var MyCtrl = function ($scope) {...})
- Is 'MyCtrl' defined in right module?
- Is "MyCtrl's" module added to app dependencies?
angular.module('app', ['app.sources']);
If you define your module multiple times, you should define it in this order:
- First define should be like
angular.module('app.sources', []);
(with [ ]
)
- Subsequent defines should be like
angular.module('app.sources');
(without [ ]
)
Important: Declaration order is important - definition with [ ]
should go first.
- Check that module is defined only once.You may have forgotten to rename module after copy-paste. Check src for string like
angular.module('app.sources', []);
Check your
'ng-app'
. Better to use only one of these with name likeng-app='app'
(In other words do not define multiple unnamed ngApp directives)Is your controller's syntax correct for your AngularJS version?
(There is a difference between definition in Angular 1.0.x and 1.2.x and higher. With Angular versions greater than 1.3.x, you cannot declare a global constructor function and use it with ng-controller)
