Javascript 角度UI引导uibModalInstance.result不产生任何值
下面是指令Javascript 角度UI引导uibModalInstance.result不产生任何值,javascript,angularjs,angular-ui-bootstrap,Javascript,Angularjs,Angular Ui Bootstrap,下面是指令CAB的代码和我的两个控制器CabinetThumbnails,ModalCtrl。根据我的要求,我使用指令cabinet和CabinetThumbnails呈现两个小部件,然后使用ModalCtrl点击每个小部件打开一个弹出窗口。小部件生成良好,弹出窗口打开良好,但(uibModalInstance.result.then(function(thumbnailData))不起作用。因此,它也不会影响服务cabinetService.getComments(thumbnailData)
CAB
的代码和我的两个控制器CabinetThumbnails
,ModalCtrl
。根据我的要求,我使用指令cabinet
和CabinetThumbnails
呈现两个小部件,然后使用ModalCtrl
点击每个小部件打开一个弹出窗口。小部件生成良好,弹出窗口打开良好,但(uibModalInstance.result.then(function(thumbnailData))
不起作用。因此,它也不会影响服务cabinetService.getComments(thumbnailData)
。这里出了什么问题?无法确定
function () {
'use strict';
angular
.module('myModule')
.directive('cabinet', function () {
return {
restrict: 'E',
replace: true,
controller: CabinetThumbnails,
controllerAs: 'ctrl',
bindToController: true,
link: link,
templateUrl: 'app/cabinet/cabinet.directive.html',
scope: {
thumbnail: '='
}
};
});
function link(scope, el, attrs) {
}
CabinetThumbnails.$inject = ['$scope','$uibModal','cabinetService'];
function CabinetThumbnails($scope,$uibModal,cabinetService) {
var vm = this;
vm.showImage = showImage;
activate();
function activate() {
}
function showImage() {
var uibModalInstance = $uibModal.open({
animation: true,
templateUrl: 'app/components/capture/cabinet.pop-up.html',
controller: ModalCtrl,
controllerAs: 'ctrl',
size: 'lg',
resolve: {
thumbnailData: function () {
return vm.thumbnail;
}
}
});
uibModalInstance.result.then(function (thumbnailData) {
spinner.spinnerShow();
//call the service to get the comments
cabinetService
.getComments(thumbnailData)
.then(function (data) {
$scope.comments = data;
})
.catch(function (err) {
growl.err('Unable to open the screen shot, Please try later !', {ttl: 20000});
})
.finally(spinner.spinnerHide);
}, function () {
$log.info('Modal dismissed at: ' + new Date());
});
}
}
ModalCtrl.$inject = ['$scope', '$uibModalInstance', 'thumbnailData', 'growl'];
function ModalCtrl($scope, $uibModalInstance, thumbnailData, growl) {
var ctrl = this;
ctrl.thumbnailData = thumbnailData;
ctrl.cancel = cancel;
function cancel() {
$uibModalInstance.dismiss();
}
}
}());
这里有几件事需要考虑:
controllerAs
,在ui引导中,您应该只使用controller:myModalController作为vm
(或者在您的情况下使用ctrl)controllerAs:'ctrl',
,但后来使用了vm
$uibModalInstance.disease()
方法,disease方法关闭模态并激活uibModalInstance.result
承诺的承诺拒绝处理程序。
您应该使用$uibModalInstance.close()
激活解析处理程序。否则,所有代码都无法运行 spinner.spinnerShow();
$uibModal.open({
animation: true,
templateUrl: 'app/components/capture/cabinet.pop-up.html',
controller: ModalCtrl as ctrl,
size: 'lg',
resolve: {
thumbnailData: function () {
return ctrl.thumbnail;
}
}
}).result
.then(function (thumbnailData) {
//call the service to get the comments
return cabinetService.getComments(thumbnailData);
}, function() {
$log.info('Modal dismissed at: ' + new Date());
}).then(function (data) {
// we get to this 'then' after cabinetService.getComments finished
$scope.comments = data;
}).catch(function (err) {
$log.err('Unable to open the screen shot, Please try later !', {ttl: 20000});
}).finally(spinner.spinnerHide);
}
加
ctrl.ok = function() {
$uibModalInstance.close(valueForResolveHandler);
};
到ModalCtrl实际上,我将服务调用移动到了引用控制器,它得到了解决并正常工作
(function () {
'use strict';
angular
.module('myModule')
.directive('cabinet', function () {
return {
restrict: 'E',
replace: true,
controller: CabinetThumbnails,
controllerAs: 'ctrl',
bindToController: true,
link: link,
templateUrl: 'app/components/capture/cabinet.directive.html',
scope: {
thumbnail: '='
}
};
});
function link(scope, el, attrs) {
}
CabinetThumbnails.$inject = ['$scope','$uibModal'];
function CabinetThumbnails($scope,$uibModal) {
var vm = this;
vm.showImage = showImage;
activate();
function activate() {
}
function showImage() {
var uibModalInstance = $uibModal.open({
animation: true,
templateUrl: 'app/components/capture/cabinet.pop-up.html',
controller: ModalCtrl,
controllerAs: 'ctrl',
size: 'lg',
resolve: {
thumbnailData: function () {
return vm.thumbnail;
}
}
});
}
}
ModalCtrl.$inject = ['$scope', '$uibModalInstance', 'thumbnailData', 'growl','cabinetService'];
function ModalCtrl($scope, $uibModalInstance, thumbnailData, growl,cabinetService) {
var ctrl = this;
ctrl.thumbnailData = thumbnailData;
ctrl.save = save;
ctrl.cancel = cancel;
//call this method to get executed while the directive loads to open the pop-up
getComments();
function getComments()
{
cabinetService
.getComments(thumbnailData)
.then(function (data) {
ctrl.comments = data;
})
.catch(function (err) {
growl.err('Unable to get comments, Please try later !', {ttl: 20000});
})
}
function save() {
var form = $scope.cabinetForm;
if (!form.$invalid && form.$dirty && form.$valid) {
var data = {
CabinetFileID: ctrl.thumbnailData.CabinetFileID,
Comment: ctrl.inputcomment
};
//call the service
cabinetService
.addComments(data)
.then(function (data) {
//refresh the comments by calling the getComments method again
ctrl.thumbnailData.CommentCount = ctrl.thumbnailData.CommentCount + 1;
getComments();
ctrl.inputcomment = '';
})
.catch(function (err) {
growl.err('Unable to add comment, please try later !', {ttl: 20000});
})
} else {
growl.info('Please enter the comment');
}
}
function cancel() {
$uibModalInstance.dismiss();
}
}
}());
您希望将ThumbModelData resolve传递给UIBModalinsance.result promise回调。我认为这不正确。请尝试将vm.thumbnail传递给cabinetService.getComments。非常感谢您的建议,但我已经尝试将服务调用移动到实际的引用控制器,一切正常哦,我也会试试你的方法。谢谢!
