通过角1.3+，你可以不再使用对全球范围的全局控制器声明（如果没有显式注册）。您需要注册使用 module.controller 语法控制器。
例如： -
angular.module（应用，[]）
.controller（'的ContactController'，['$范围，功能的ContactController（$范围）{
$ scope.contacts = [abcd@gmail.com，abcd@yahoo.co.in]; $ scope.add =功能（）{
$ scope.contacts.push（$ scope.newcontact）;
$ scope.newcontact =; };
}]）;
或
函数的ContactController（$范围）{
$ scope.contacts = [abcd@gmail.com，abcd@yahoo.co.in]; $ scope.add =功能（）{
$ scope.contacts.push（$ scope.newcontact）;
$ scope.newcontact =;
};
}
。ContactController中注入$ ='$范围'];
angular.module（'应用'，[]）控制器（'的ContactController'，ContactController中）。
有断裂的变化，但它可以被关闭以使用全局 allowGlobals 。
例如： -
angular.module（应用）
的.config（['$ controllerProvider'，函数（$ controllerProvider）{
$ controllerProvider.allowGlobals（）;
}]）;
下面是角源注释： -
- 检查是否与给定名称的控制器通过
$ controllerProvider注册
- 检查评估对当前范围字符串返回构造
- 如果$ controllerProvider＃allowGlobals，检查
窗口[构造]对全球窗口对象（不推荐）
块引用>.....前pression = controllers.hasOwnProperty（构造函数）
？控制器[构造]
：吸气剂（当地人$范围，构造，真）||
（？全局吸气剂（$窗口，构造，真）：未定义）;一些额外的检查： -
做确保把APPNAME在
NG-应用指令的角根元素（如： -HTML），以及。例如： - NG-应用=对myApp如果一切正常，你仍然得到问题，千万记得要确保你有包含在脚本中正确的文件。
您还没有在不同的地方，这导致在同一模块上定义previously的任何实体定义同一模块两次被清理出局，例如
angular.module（应用 ，[]）。控制器（..，又在另一个地方angular.module（应用，[]）。服务（..（与包括当然两者的脚本）会导致previously注册控制器模块应用要与模块的第二娱乐清除出去。
I am writing a sample application using angularjs. i got an error mentioned below on chrome browser.
Error is

With Angular 1.3+ you can no longer use global controller declaration on the global scope (Without explicit registration). You would need to register the controller using
module.controllersyntax.Example:-
angular.module('app', []) .controller('ContactController', ['$scope', function ContactController($scope) { $scope.contacts = ["abcd@gmail.com", "abcd@yahoo.co.in"]; $scope.add = function() { $scope.contacts.push($scope.newcontact); $scope.newcontact = ""; }; }]);or
function ContactController($scope) { $scope.contacts = ["abcd@gmail.com", "abcd@yahoo.co.in"]; $scope.add = function() { $scope.contacts.push($scope.newcontact); $scope.newcontact = ""; }; } ContactController.$inject = ['$scope']; angular.module('app', []).controller('ContactController', ContactController);It is a breaking change but it can be turned off to use globals by using
allowGlobals.Example:-
angular.module('app') .config(['$controllerProvider', function($controllerProvider) { $controllerProvider.allowGlobals(); }]);Here is the comment from Angular source:-
- check if a controller with given name is registered via
$controllerProvider- check if evaluating the string on the current scope returns a constructor
- if $controllerProvider#allowGlobals, check
window[constructor]on the globalwindowobject (not recommended)
..... expression = controllers.hasOwnProperty(constructor) ? controllers[constructor] : getter(locals.$scope, constructor, true) || (globals ? getter($window, constructor, true) : undefined);Some additional checks:-
Do Make sure to put the appname in
ng-appdirective on your angular root element (eg:-html) as well. Example:- ng-app="myApp"If everything is fine and you are still getting the issue do remember to make sure you have the right file included in the scripts.
You have not defined the same module twice in different places which results in any entities defined previously on the same module to be cleared out, Example
angular.module('app',[]).controller(..and again in another placeangular.module('app',[]).service(..(with both the scripts included of course) can cause the previously registered controller on the moduleappto be cleared out with the second recreation of module.
