javascript - $scope.$apply 返回错误 undefined is not a function

Question

我在 ng-click 中运行此函数，但收到错误 TypeError: undefined is not a function on this line : $scope.$apply(function () {

app.controller('MainControl', function($scope, $http){

$scope.add = function(){

    $http({
        url: "php/insert.php",
        method: "POST",
        data: {
            'myId': myId
        },
        headers: {
            'Content-Type': 'application/x-www-form-urlencoded'
        }
    }).success(function (data, status, headers, config) {

        $scope.$apply(function () {
            $scope.currentId = data;
        });

    }).error(function (data, status, headers, config) {});

    $scope.tabs.push({
        "currentId": $scope.currentId
    });

}

    });

这里不需要

$scope.$apply() 。移动

$scope.tabs.push({
        "currentId": $scope.currentId
    });

到http promise 的成功回调

app.controller('MainControl', function($scope, $http){

$scope.add = function(){

    $http({
        url: "php/insert.php",
        method: "POST",
        data: {
            'myId': myId
        },
        headers: {
            'Content-Type': 'application/x-www-form-urlencoded'
        }
    }).success(function (data, status, headers, config) {

        $scope.currentId = data;
        $scope.tabs.push({
            "currentId": $scope.currentId
        });

    }).error(function (data, status, headers, config) {});



}

    });
