javascript - 如何使在 ngDialog 模式中所做的更改出现在主页上

Question

我是 AngularJs 和 ngDialog 的新手，我无法让我的绑定(bind)在 ngDialog 模式和我的 Controller 之间工作。我通过指定 { scope: $scope } 将 Controller 的作用域注入(inject)到模态中，并且我可以访问 Controller 中定义的方法，但是与 Controller 中定义的模型的绑定(bind)无法正常运行。

我正在尝试使用模式来允许用户向组织添加地址。

这是 main.js

var App = angular.module('App', ['ngRoute', 'ngCookies', 'ngDialog']);

...

App.controller('PageOrganization', function($scope, $rootScope, ngDialog, $route, $location){
    $scope.addAddressFormData = {};

    $scope.addAddress = function(){
        ngDialog.open({
            template: 'partials/modals/add-address.html',
            controller: 'PageOrganization',
            scope: $scope
        });
    };

    $scope.saveAddress = function(){
        console.log($scope.addAddressFormData);
        $scope.organization.addresses.push($scope.addAddressFormData);
        console.log($scope.organization);
    };

    // STUBBED OUT ORGANIZATION
    $scope.organization = {
        org_type: "nonprofit",
        name: 'New Organization',
        addresses: [],
        phoneNumber: "",
        faxNumber: "",
        emailAddress: "",
        website: "",
        primaryContact: "",
        primaryEmail: "",
        imageUrl: "",
        isPrivate: false,
        campaigns: [],
        admins: []
    };

这是 organization.html:

...

<button ng-click="addAddress()">Add an Address</button>
<h1>Addresses</h1>
<ul>
    <li ng-repeat="address in organization.addresses">
        <p>
            {{address.type}} <br>
            {{address.addressLine1}} <br>
            {{address.addressLine2}} <br>
            {{address.city}} <br>
            {{address.state}} <br>
            {{address.postalCode}}
        </p>
    </li>
  </ul>

这是 add-address.html:

<h1>Add an Address</h1>
<form ng-submit="saveAddress()">
    <select name="type">
        <option value="business" default="selected">Business</option>
        <option value="residence">Residence</option>
    </select>
    <input ng-model="addAddressFormData.addressLine1" type="text" placeholder="Address Line 1">
    <input ng-model="addAddressFormData.addressLine2" type="text" placeholder="Address Line 2">
    <input ng-model="addAddressFormData.city" type="text" placeholder="City"> 
    <select ng-model="addAddressFormData.state">
       <option value="AL">Alabama</option>

       <option value="MS">Mississippi</option>
       <option value="MO">Missouri</option>

       <option value="NJ">New Jersey</option>
       <option value="NM">New Mexico</option>
       <option value="NY">New York</option>

       <option value="OK">Oklahoma</option>
       <option value="OR">Oregon</option>
       <option value="PA">Pennsylvania</option>
       <option value="RI">Rhode Island</option>
       <option value="SC">South Carolina</option>
       <option value="SD">South Dakota</option>
       <option value="TN">Tennessee</option>
       <option value="TX">Texas</option>
       <option value="UT">Utah</option>
       <option value="VT">Vermont</option>
       <option value="VA">Virginia</option>
       <option value="WA">Washington</option>
       <option value="WV">West Virginia</option>
       <option value="WI">Wisconsin</option>
       <option value="WY">Wyoming</option>
    </select>
    <input ng-model="addAddressFormData.postalCode" type="text" placeholder="Postal Code"> 
    <input type="submit" value="Save Address">
</form>

模态可以访问父作用域；它成功调用了 $scope.saveAddress() 和 console.log($scope.organization) 记录了整个组织，包括在模态中添加的新地址。但是，新地址并没有反射(reflect)在organization.html 中的ng-repeat 中，如果我依次添加多个地址，日志中只会显示最近的一个。

作为实验，我将这个函数添加到 main.js 中:

$scope.pushAddress = function(){
    $scope.addAddressFormData = {city: $scope.organization.addresses.length + 1};
    console.log($scope.addAddressFormData);
    $scope.organization.addresses.push($scope.addAddressFormData);
    console.log($scope.organization);
};

并更改了 organization.html 中的“添加地址”按钮以匹配:

<button class="button color-c vertical-a float-right" ng-click="pushAddress()">Add an Address</button>

现在，当我点击“添加地址”时，新地址会立即显示在 ng-repeat 中，并且每个控制台日志都包含所有地址，而不仅仅是最近的地址。

这两种方法有什么区别？为什么在使用 Controller 范围内的方法进行模态更改时，它们会“过期”？

Answer 1

不要将 controller 参数传递给 ngDialog.open。当您这样做时，将为该对话框实例创建一个新的 Controller ，这就是您看到它“工作”的原因。它访问的是其他 Controller 实例的范围和变量，而不是您传入的 $scope 中的实例。

因此只需将打开的对话框代码更改为此即可:

$scope.addAddress = function(){
    ngDialog.open({
        template: 'partials/modals/add-address.html',
        scope: $scope
    });
};

这是一个working plunker我创造的。
