【中文标题】如何在模态关闭时刷新 ng-repeat?【英文标题】:How to refresh ng-repeat on modal close? 【发布时间】:2015-04-22 16:13:39 【问题描述】:设置: 我有一个页面(角度),里面有一个转发器。
<tr ng-repeat="row in results.leads">
<td>row.SubmittedByName</td>
在转发器中,有一列带有一个按钮,可以打开一个模态来更改该行的数据。模态,反过来,有一个用于保存记录的按钮,关闭当前模态,打开一个新模态,让用户输入评论,保存,然后关闭模态。
这一切都很好。太棒了。
不起作用的是...当模式关闭时,ng-repeat 应该刷新,因为在模式中采取的操作实际上会从数据中删除行。如果我手动刷新页面,该行就会消失 - 但不刷新页面,什么也不会发生。
角度控制器: '使用严格';
angular.module('leadApproval.controllers', []).
//This is the main page core method - The data is loaded here, and the in-table-row buttons work from here.
controller('LeadApprovalCtrl', function ($scope, $location, $modal, api, notificationService)
$scope.currentPage = 1;
$scope.pageSize = 13;
$scope.loaded = false;

$scope.setPage = null;
$scope.results = null;
$scope.loadQueue = (function ()
api.queue.load(function (data)
if (data.error)
notificationService.error('<h4>An error occurred..</h4>' + data.error);
else
$scope.results = data;
$scope.loaded = true;
);
);
$scope.acceptLead = function (leadId)
var modal = $modal.open(
templateUrl: '/Content/LeadApproval/Approved.html',
controller: 'ApprovedCtrl',
windowClass: '',
resolve: leadId: function () return leadId;
);
modal.result.then(function (result)
if (result === 'save')
$scope.loadQueue();
notificationService.success('Lead successfully approved.');
);
$scope.searchLead = function (id)
$location.path('search/' + id);
$scope.rejectLead = function (leadId)
var modal = $modal.open(

$scope.editLead = function (id)
window.location = "/Customers/Edit/" + id;
// Open Lead Detail
var leadHistoryOverviewScope =
item:
;
$scope.showLeadDetail = function (customerId, leadId)
leadHistoryOverviewScope.item = customerId: customerId, leadOppId: leadId ;
var modal = $modal.open(
templateUrl: '/content/leadApproval/leaddetail.html',
controller: 'LeadHistoryCtrl',
windowClass: 'wide-modal-window',
resolve: childScope: function () return leadHistoryOverviewScope;
);
;
$scope.loadQueue();
).
// Lead History controller
controller('LeadHistoryCtrl', function ($scope, $modal, $modalInstance, api, notificationService, childScope)
$rootScope.loaded = false;
$scope.customerLoaded = false;
var historyStartDate = new moment().subtract(6, 'months').format("YYYY-MM-DD");
var historyEndDate = new moment().format("YYYY-MM-DD");
$scope.orders = [];
$scope.history = [];
$scope.showActionButtons = true;
api.queue.queryOrders(childScope.item.customerId, historyStartDate, historyEndDate, function (result)
$scope.orders = result || [];
$scope.ordersLoaded = true;
);
api.queue.details.get( id: childScope.item.customerId, leadOppId: childScope.item.leadOppId , function (result)
$scope.history = result;
$scope.customerLoaded = true;
);
$scope.acceptLead = function (leadId)
$modalInstance.close();
var modal = $modal.open(
templateUrl: '/Content/LeadApproval/Approved.html',
controller: 'ApprovedCtrl',
windowClass: '',
resolve: leadId: function () return leadId;
);
modal.result.then(function (result)
if (result === 'save')
$scope.loadQueue();
notificationService.success('Lead successfully approved.');
);
$scope.rejectLead = function (leadId)
$modalInstance.close();
var modal = $modal.open(
templateUrl: '/Content/LeadApproval/NotApproved.html',
controller: 'NotApprovedCtrl',
windowClass: '',
resolve: leadId: function () return leadId;
);
modal.result.then(function (result)
if (result === 'save')
$scope.loadQueue();
notificationService.success('Lead successfully removed from queue.');
);
;
$scope.editLead = function (id)
$modalInstance.close();
window.location = "/Customers/Edit/" + id;
$scope.cancel = function ()
$modalInstance.dismiss('cancel');
;
)
;
我注意到$scope.loadQueue();
(大约 17 行)作为未定义对象抛出错误。由于某种原因,“LeadHistoryCtrl”在“LeadApprovalCtrl”中看不到范围,因此无法刷新 ng-repeat。我什至尝试将 loadQueue 函数复制到 LeadHistoryCtrl 中,但没有真正的效果 - 代码然后运行......但主页没有刷新。
那么,问题来了: 如何让 LoadHistoryCtrl 中的 loadQueue() 调用来调用 LeadApprovalCtrl 中的方法,并刷新主页 ng-repeat 表?
【问题讨论】:
关闭模式后,您不会修改用于ng-repeat
的模型,因此它不会改变
这就是$scope.loadQueue();
应该做的——回调 LeadApprovalCtrl 的 loadQueue 函数实例,以更新模型。
你的 HTML 是什么样的,控制器是相互嵌套的,还是有父控制器?创建服务将是跨控制器通信的最佳方式,但如果您真的反对,嵌套控制器可以允许一些通信。 This video 更详细地介绍。
【参考方案1】:
如果您需要从多个控制器访问该功能,通常您会希望将该功能移至服务中。在 Angular 中,您不能从控制器直接与另一个控制器通信。您可以使用 $scope.broadcast / $scope.emit 来触发它。 What's the correct way to communicate between controllers in AngularJS?
【讨论】:
我可以接受,除了我实际上是在另一个页面上进行跨控制器通信(这只会增加我的困惑,因为它在那里工作而在这里不起作用)。跨度> 你能把它扔进小提琴或plnkr吗?我想看看交叉通信的代码。 正如blindworld所说,如果你嵌套控制器,你可以允许一些通信,如这个plnkr plnkr.co/edit/LH81qIl6wpmjdxVHDOUE?p=preview以上是关于如何在模态关闭时刷新 ng-repeat?的主要内容,如果未能解决你的问题,请参考以下文章
