我对离子很陌生,不是棱角分明的专业人士。我正在尝试为可以从控制器调用的弹出窗口创建一个服务。我正在使用一项服务,因为多个控制器可能需要使用弹出窗口,并且我可能需要不同类型的弹出窗口。我什至不确定这是正确的方法,请原谅我,但我正在试验。我希望服务将哪个按钮(确定/取消)传回控制器,以便可以添加或不添加案例。
非常感谢。
弹出服务
angular.module('services')
.service('popupService', function ($ionicPopup) {
return {
createCasePopup : function () {
$ionicPopup.show({
cssClass: 'custom-popup',
title: 'Create Case',
subTitle: 'Are you sure you want to create this case?',
buttons: [
{
text: 'Cancel',
onTap: function (e) {
return 'cancel button pressed';
}
},
{
text: 'Ok',
type: 'button-positive',
onTap: function (e) {
return 'ok button pressed';
}
},
]
}).then(
function (res) {
console.log(res);
},
function (err) {
console.log('Err:', err);
},
function (msg) {
console.log('message:', msg);
});
}
}
});
控制器
$scope.addCase = function () {
// this line to return which button has been clicked?
var createCase = popupService.createCasePopup();
if (createCase && $scope.case) {
caseService.add($scope.case);
}
};
尝试过使用 $q 在服务中创建可以在弹出窗口解析处理程序中解析的延迟承诺?

由于您想要一个弹出窗口,因此也来自服务,因此最适合您的方式是$ionicModal
这是一个工作示例。

.JS
angular.module('evenementoApp', ['ionic'])
.service('ModalService', function($ionicModal, $rootScope) {
var init = function(tpl, $scope) {
var promise;
$scope = $scope || $rootScope.$new();
promise = $ionicModal.fromTemplateUrl(tpl, {
scope: $scope,
animation: 'slide-in-up'
}).then(function(modal) {
$scope.modal = modal;
return modal;
});
$scope.openModal = function() {
$scope.modal.show();
};
$scope.closeModal = function() {
$scope.modal.hide();
};
$scope.$on('$destroy', function() {
$scope.modal.remove();
});
return promise;
}
return {
init: init
}
})
.controller('MainCtrl', function($scope, ModalService) {
$scope.modal1 = function() {
ModalService
.init('modal1.html', $scope)
.then(function(modal) {
modal.show();
});
};
$scope.modal2 = function() {
ModalService
.init('modal2.html')
.then(function(modal) {
modal.show();
});
};
})
这是一个有效的代码笔
