我一直在' $ scope未定义' AngularJS中此控制器代码的控制台错误:
angular.module('articles').controller('ArticlesController', ['$scope', '$routeParams', '$location', 'Authentication', 'Articles',
function($scope, $routeParams, $location, Authentication, Articles){
$scope.authentication = Authentication;
}
]);
$scope.create = function() { // THROWS ERROR ON THIS INSTANCE OF $SCOPE
var article = new Articles({
title: this.title,
content: this.content
});
article.$save(function(response) {
$location.path('articles/' + response._id);
}, function(errorResponse) {
$scope.error = errorResponse.data.message;
});
};
在我的AngularJS MVC文件中,我应该在哪里查找$ scope未正确定义的问题?

对于从Google登陆的其他人,如果您在为缩小功能注释功能时忘记$scope
周围的引号,则会收到此错误。
app.controller('myCtrl', [$scope, function($scope) {
...
}]);
app.controller('myCtrl', ['$scope', function($scope) {
...
}]);

将该代码放在控制器中: -
angular.module('articles').controller('ArticlesController', ['$scope', '$routeParams', '$location', 'Authentication', 'Articles',
function($scope, $routeParams, $location, Authentication, Articles){
$scope.authentication = Authentication;
$scope.create = function() { // THROWS ERROR ON THIS INSTANCE OF $SCOPE
var article = new Articles({
title: this.title,
content: this.content
});
article.$save(function(response) {
$location.path('articles/' + response._id);
}, function(errorResponse) {
$scope.error = errorResponse.data.message;
});
};
}
]);

只需在控制器中放入$ scope.create函数即可。不在外面!
$ scope仅在控制器中定义,每个控制器都有自己的。所以在你的控制器外面编写$ scope是行不通的。

检查控制器定义后声明的范围变量。 例如:
var app = angular.module('myApp','');
app.controller('customersCtrl', function($scope, $http) {
//define scope variable here.
});
在视图页面中检查控制器的已定义范围。
例如:
<div ng-controller="mycontroller">
//scope variable used inside these blocks
<div>
