Question

我第一次接受依赖注射。我的目标是最终只在两个控制器之间启用一些简单的通信。我甚至没有足够甚至担心处理与第二个控制器的通信。我收到了ContactMessages.AddNewContact（response.data）的“不是函数错误”;

当我使用self.ContactMessages.AddNewContact（response.data）;我得到“无法读取未定义的属性'AddNewContact'”

我只想调用ContactMessages工厂的AddNewContact函数。

这应该是一个相当基本的程序。

<html ng-app="myApp"><head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular.min.js"></script>
<script>
var userName = 'some email'; //pseudo code
var app = angular.module('myApp', []);

app.factory('ContactMessages', [function() 
{   var tmpContact = {};

    this.AddNewContact = function(objContact){
        this.tmpContact = objContact;
    };
    return tmpContact;
}]);

app.controller('ActionsController', function ($scope, $http, ContactMessages){
        this.newContact = {
            Email: "",
            Type: "",
            Frequency: "",
            UserName: userName
        };
        var self = this;

        this.AddContact=function()
        {   

            $http({
            method: 'POST',
            url: 'some url', //pseudo code
            data: this.newContact,
            headers: { 'Content-Type': 'application/x-www-form-urlencoded'} 
            }).then(function successCallback(response) 
                {   if(angular.isObject(response.data))
                        self.ContactMessages.AddNewContact(response.data);
                }, function errorCallback(response) {

            });
        };
    }); 
</script>
</head>

<body ng-controller="ActionsController as ActCtrl">
<div>
    <form name="frmAddContact" noValidate>
        <input placeholder="Contact Email" type="email" ng-model="ActCtrl.newContact.Email" required></input>
        <select ng-model="ActCtrl.newContact.Type"  required>
            <option value="">Contact Type</option>
            <option value="COLLEAGUE">Colleague</option>
            <option value="FRIEND">Friend</option>
            <option value="FAMILY">Family</option>
        </select>
        <select ng-model="ActCtrl.newContact.Frequency"  required>
            <option value="">Contact Frequency</option>
            <option value="ANY">Any Time</option>
            <option value="WEEKLY">Weekly</option>
            <option value="MONTHLY">Monthly</option>
            <option value="QUARTERLY">Quarterly</option>
            <option value="YEARLY">Yearly</option>
        </select>
        <div >
            <button ng-click="ActCtrl.AddContact()" ng-disabled="frmAddContact.$invalid" >Add Contact</button>
        </div>
    </form>
</div></body></html>
