javascript - 未从范围获取值，出现错误 : Cannot set property 'value' of undefined

Question

var app = angular.module("Main", []);

app.controller("MainCtrl", [ function ($scope) {
    $scope.value = 545
}]);` 
var app = angular.module("Main", []);

app.controller("MainCtrl", [ function ($scope) {
    $scope.value = 545
}]);

Answer 1

您 DI 错误，您需要将 $scope 作为参数和列表添加到数组中。

app.controller("MainCtrl", ["$scope", function ($scope) {
    $scope.value = 545
}]);

或者你必须这样做:

app.controller("MainCtrl", function ($scope) {
    $scope.value = 545
});

推荐第一个，因为第二个仅适用于未缩小的代码。
