我想在执行动作之前向用户显示一个弹出式警告模式(在这种情况下删除)。如果他们点击模型中的okay
,它会继续,如果他们点击cancel
,它会执行其他操作。Angular modal return promise
要做到这一点,我试图通过模式承诺沿着链回到最初呼吁$rootScope.openDirections('warning').then(...
,所以我可以决定在那里做什么。
但是我得到错误:
$ rootScope.openDirections(...),那么是不是一个函数at Scope.$scope.deleteObj
告诉我,不返回的承诺:
$scope.deleteObj = function (id, type) {
$rootScope.openDirections('warning').then(function (res) {
// Do Stuff
}, function (err) {
console.log('ERROR', err);
});
这调用一个$ rootScope函数:(我看到这里的对象类型是一个承诺...所以不应该能够现在返回到原来的调用者?)
$rootScope.openDirections = function (type) {
// A Promise: Object {result: Promise, opened: Promise, rendered: Promise}
return Modal.showDirections(type);
};
其中要求Modal
工厂开方向模态:
return {
...
showDirections: function(type) {
return $modal.open({
backdrop: 'static',
templateUrl: 'modal.html',
controller: 'directionsCtrl',
resolve: {
// Display custom modal template
obj: function() {
if (type === 'markdown') {
return {
template: '/modals/directions.html'
};
} else {
return {
template: '/modals/message.html'
};
}
},
testID : function() {
return 'WHAT DO I RETURN HERE?';
}
}
});
}
这使得message.html
模式的模板:
<div class="admin-directions">
<div class="directions">
ARE YOU SURE YOU WANT TO DELETE THIS?
</div>
<p class="dismiss-admin-help" ng-click="okay()">Okay</p>
<p class="dismiss-admin-help" ng-click="cancel()">Cancel</p>
</div>
这对于模态使用directionsCtrl
:
angular
.module('DDE')
.controller('directionsCtrl', ['$rootScope', '$scope', '$modalInstance', 'Modal', 'obj', 'Auth', 'VARS', '$route', '$location', 'testID',
function ($rootScope, $scope, $modalInstance, Modal, obj, Auth, VARS, $route, $location, testID) {
$scope.template = obj.template;
$scope.testID = '';
/**
* Dismiss modal
*/
$scope.ok = function() {
$scope.testID = 'okay';
return $modalInstance.result($scope.testID);
};
$scope.cancel = function() {
$scope.testID = 'cancel';
return $modalInstance.result($scope.testID);
};
}]);
好了,我的'$ modal'实例不是在同一控制器,而是在自己的工厂。因此,我在工厂内完全“解析”什么以回传给原始呼叫者? – Growler
你是什么意思?当你做了我建议的事情后,你的错误消失了吗? – mcgraphix
'$ scope.ok'和'$ scope.cancel'按钮不再适用于模态 – Growler
