angular里$.post无法绑定到$scope里（$.post、$http.post用法区别）

如下所示，如果$scope.equipments=...那一段，放在$.post里就不能绑定到$scope.equipments上，如果放在外面就可以，这是为什么？

mainApp.controller('equipmentsController', function($scope, $http) {
    $.post("getAllDeviceList.action",
            {},
            function(response){
                    $scope.equipments = [ {
                        "id" : "1",
                        "name" : "equipment01 ",
                        "number" : "11"
                    }, {
                        "id" : "2",
                        "name" : "equipment02 ",
                        "number" : "22"
                    }, {
                        "id" : "3",
                        "name" : "equipment03 ",
                        "number" : "33"
                    } ];

            }
    );

    $scope.equipments = [ {
        "id" : "1",
        "name" : "equipment01 ",
        "number" : "11"
    }, {
        "id" : "2",
        "name" : "equipment02 ",
        "number" : "22"
    }, {
        "id" : "3",
        "name" : "equipment03 ",
        "number" : "33"
    } ];

}

搞不懂楼主用$.post的意义。你注入$http又有何意义

---

你的$.post不是angular的方法，所以实际上post的回调虽然执行了，但angular在视图上却不知道这件事。你可以在$.post里的赋值操作后面再跟一句$scope.$apply();，那个赋值操作就生效了。

经过@lee1994522 的提醒，意识到如果用了$.post方法，那么脱离了angular的上下文，所以无法绑定到angular的$scope里。

this is the point,pls.. $.post is not an Angular issue and the stuff
it wraps is not in an Angular world,so it's obviously that the
equipments outside is in Angular's world and it works as you expect

try $scope.$apply() when you call a "none Angular" issue if you wanna
refresh sth

解决办法有两个：

$.post

第一个诚如@lee1994522所说，直接在$.post的回调函数的最后加上一句$scope.$apply()，把改变同步绑定到视图上

$.post("xxx.action",
            {},
            function(response){
                if(response.result == "success"){
                    ...
                    }
                    $scope.equipments = equipments; 
                    $scope.$apply();
                }
            },
            "json"
    );

$http.post

AngularJS - Any way for $http.post to send request parameters instead of JSON

全局里定义：

var app = angular.module('myApp');

app.config(function ($httpProvider) {
    $httpProvider.defaults.transformRequest = function(data){
        if (data === undefined) {
            return data;
        }
        return $.param(data);
    }
    $httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded; charset=UTF-8';
});

然后控制器里面写：

   $http.post("xxx.action").success(function(response) {  
            ...
            $scope.equipments = equipments; 
    });
