如何在 Angular 中添加可重用的模态对话框? [英] How do I add a reusable modal dialog in Angular?

问题描述

我是 Angular 的新手，正在尝试实现 这个解决方案 到我的项目中.

I'm new to Angular and attempting to implement this solution into my project.

它看起来很简单，但是，我正试图将它变成一个可重用的元素，以便我可以从任何地方调用它并传入要显示的内容(否则，有什么意义?).

It looks painfully easy, however, I'm trying to make this into a re-usable element so that I can call it from anywhere and just pass in the content to be shown (otherwise, what's the point?).

所以，我的具体问题是:假设我已经有一个绑定到某个 DOM 元素的 controller 并且它具有获取一些 factory 驱动的 的功能>$http 调用并在响应时我希望通过此对话框通知用户某事，如何将 *this 指令和 *this 控制器与我现有的指令结合起来，以及如何以允许的方式进行操作然后我从一个完全不同的 controller 再次使用它?

So, my specific question is: assuming I already have a controller that's bound to some DOM element and it has a feature that goes and fetches some factory driven $http call and upon the response I wish to notify the user via this dialog of something, how do I combine *this directive and *this controller with my existing one and how do I do it in a way that allows me to then use it again from a totally different controller?

或者这可能是这个用途的一个坏例子，我应该看一个不同的例子吗?

Or is this perhaps a bad example for this use and should I be looking at a different one?

推荐答案

与其他选项相比，下面给出了极简主义的方法，使用角度工厂.请参阅下面的示例片段.

Compared to other options, below given the minimalist approach, using angular factory. See a sample snippet below.

注意:使用 Angular JS 和 UI Bootstrap - AngularUI.

Note: using Angular JS with UI Bootstrap - AngularUI.

1. 可重复使用的模式视图 - ConfirmationBox.html

<div class="modal-header">
  <h3 class="modal-title">{{title}}</h3>
</div>
<div class="modal-body">
  {{message}}
</div>
<div class="modal-footer">
  <button type="button" class="btn btn-primary btn-warn" data-ng-click="ok(); $event.stopPropagation()">OK</button>

  <button type="button" class="btn btn-default" data-ng-click="cancel(); $event.stopPropagation()">Cancel</button>
</div>

1. 可重用模块和共享工厂，用于处理可重用的模态对话框

angular.module('sharedmodule',['ui.bootstrap', 'ui.bootstrap.tpls'])
.factory("sharedService",["$q", "$modal", function ($q, $modal)
{
    var _showConfirmDialog = function (title, message)
    {
        var defer = $q.defer();

        var modalInstance = $modal.open({
            animation: true,
            size: "sm",
            templateUrl: 'ConfirmationBox.html',
            controller: function ($scope, $modalInstance)
            {
                $scope.title = title;
                $scope.message = message;

                $scope.ok = function ()
                {
                    modalInstance.close();
                    defer.resolve();
                };

                $scope.cancel = function ()
                {
                    $modalInstance.dismiss();
                    defer.reject();
                };
            }
        });

        return defer.promise;
    }

    return {

        showConfirmDialog: _showConfirmDialog
    };

}]);

1. 部分视图，使用共享模式对话框

<a data-ng-click="showConfirm()">Go Back to previous page</a>

1. 视图控制器，打开共享的可重用模式对话框并处理通知(确定和取消)

var myModule = angular.module("mymodule", ['sharedmodule', 'ui.bootstrap', 'ui.bootstrap.tpls']);

myModule.controller('myController', ["$scope", "sharedService", "$window",
function ($scope, sharedService, $window)
{
    $scope.showConfirm = function ()
    {
        sharedService.showConfirmDialog(
            'Confirm!',
            'Any unsaved edit will be discarded. Are you sure to navigate back?')
            .then(function ()
            {
                $window.location = '#/';
            },
            function ()
            {
            });
    };
}]);
