我正在尝试清理我的一个控制器的代码，这些代码变得太大了。首先，我决定将使用AngularJS Material mdDialog的与会者注册转移到该服务。
原始（和工作）控制器代码如下所示：
myApp.controller('RegistrationController', ['$scope','$routeParams','$rootScope','$location','$filter','$mdDialog', function($scope, $routeParams, $rootScope, $location, $filter, $mdDialog){
var attendee = this;
attendees = [];
...
$scope.addAttendee = function(ev) {
$mdDialog.show({
controller: DialogController,
templateUrl: 'views/regForm.tmpl.html',
parent: angular.element(document.body),
targetEvent: ev,
clickOutsideToClose:true,
controllerAs: 'attendee',
fullscreen: $scope.customFullscreen, // Only for -xs, -sm breakpoints.
locals: {parent: $scope}
})
.then(function(response){
attendees.push(response);
console.log(attendees);
console.log(attendees.length);
})
};
function DialogController($scope, $mdDialog) {
var attendee = this;
$scope.hide = function() {
$mdDialog.hide();
};
$scope.cancel = function() {
$mdDialog.cancel();
};
$scope.save = function(response) {
$mdDialog.hide(response);
};
}
}]);
和分离后控制器的代码：
myApp.controller('RegistrationController', ['$scope','$routeParams','$rootScope','$location','$filter','$mdDialog','Attendees', function($scope, $routeParams, $rootScope, $location, $filter, $mdDialog, Attendees){
...
$scope.attendees= Attendees.list();
$scope.addAttendee = function (ev) {
Attendees.add(ev);
}
$scope.deleteAttendee = function (id) {
Attendees.delete(id);
}
}]);
新服务代码如下：
myApp.service('Attendees', ['$mdDialog', function ($mdDialog) {
//to create unique attendee id
var uid = 1;
//attendees array to hold list of all attendees
var attendees = [{
id: 0,
firstName: "",
lastName: "",
email: "",
phone: ""
}];
//add method create a new attendee
this.add = function(ev) {
$mdDialog.show({
controller: DialogController,
templateUrl: 'views/regForm.tmpl.html',
parent: angular.element(document.body),
targetEvent: ev,
clickOutsideToClose:true,
controllerAs: 'attendee',
fullscreen: this.customFullscreen, // Only for -xs, -sm breakpoints.
//locals: {parent: $scope}
})
.then(function(response){
attendees.push(response);
console.log(attendees);
console.log(attendees.length);
})
};
//simply search attendees list for given id
//and returns the attendee object if found
this.get = function (id) {
for (i in attendees) {
if (attendees[i].id == id) {
return attendees[i];
}
}
}
//iterate through attendees list and delete
//attendee if found
this.delete = function (id) {
for (i in attendees) {
if (attendees[i].id == id) {
attendees.splice(i, 1);
}
}
}
//simply returns the attendees list
this.list = function () {
return attendees;
}
function DialogController($mdDialog) {
this.hide = function() {
$mdDialog.hide();
};
this.cancel = function() {
$mdDialog.cancel();
};
this.save = function(response) {
$mdDialog.hide(response);
};
}
}]);
但我无法从生成的mdDialog框中“保存”，该框使用ng-click=save(attendee)并未关闭对话框。
我做错了什么？

使用“controllerAs”语法实例化控制器时，请使用实例化的名称：
<button ng-click="ctrl.save(ctrl.attendee)">Save</button>
this.add = function(ev) {
$mdDialog.show({
controller: DialogController,
templateUrl: 'views/regForm.tmpl.html',
parent: angular.element(document.body),
targetEvent: ev,
clickOutsideToClose:true,
controllerAs: ̶'̶a̶t̶t̶e̶n̶d̶e̶e̶'̶ 'ctrl',
fullscreen: this.customFullscreen, // Only for -xs, -sm breakpoints.
//locals: {parent: $scope}
})
.then(function(response){
attendees.push(response);
console.log(attendees);
console.log(attendees.length);
return response;
});
为避免混淆，请选择与数据名称不同的控制器实例名称。

$ scope在创建时无法注入服务。您需要重构服务及其方法，以便不向其中注入$ scope，而是在调用时将当前作用域传递给服务方法。
我实际上有一个注入的通知模块，它使用$ mdDialog。下面是它的代码。也许它会有所帮助。
(() => {
"use strict";
class notification {
constructor($mdToast, $mdDialog, $state) {
/* @ngInject */
this.toast = $mdToast
this.dialog = $mdDialog
this.state = $state
/* properties */
this.transitioning = false
this.working = false
}
openHelp() {
this.showAlert({
"title": "Help",
"textContent": `Help is on the way for ${this.state.current.name}!`,
"ok": "OK"
})
}
showAlert(options) {
if (angular.isString(options)) {
var text = angular.copy(options)
options = {}
options.textContent = text
options.title = " "
}
if (!options.ok) {
options.ok = "OK"
}
if (!options.clickOutsideToClose) {
options.clickOutsideToClose = true
}
if (!options.ariaLabel) {
options.ariaLabel = 'Alert'
}
if (!options.title) {
options.title = "Alert"
}
return this.dialog.show(this.dialog.alert(options))
}
showConfirm(options) {
if (angular.isString(options)) {
var text = angular.copy(options)
options = {}
options.textContent = text
options.title = " "
}
if (!options.ok) {
options.ok = "OK"
}
if (!options.cancel) {
options.cancel = "Cancel"
}
if (!options.clickOutsideToClose) {
options.clickOutsideToClose = false
}
if (!options.ariaLabel) {
options.ariaLabel = 'Confirm'
}
if (!options.title) {
options.title = "Confirm"
}
return this.dialog.show(this.dialog.confirm(options))
}
showToast(toastMessage, position) {
if (!position) { position = 'top' }
return this.toast.show(this.toast.simple()
.content(toastMessage)
.position(position)
.action('OK'))
}
showYesNo(options) {
options.ok = "Yes"
options.cancel = "No"
return this.showConfirm(options)
}
uc() {
return this.showAlert({
htmlContent: "<img src='img\\underconstruction.jpg'>",
ok: "OK",
title: "Under Construction"
})
}
}
notification.$inject = ['$mdToast', '$mdDialog', '$state']
angular.module('NOTIFICATION', []).factory("notification", notification)
})()
然后将通知（小写）注入我的控制器以便使用它。我将通知存储在控制器的属性中，然后使用以下内容调用它：
this.notification.showYesNo({
clickOutsideToClose: true,
title: 'Delete Customer Setup?',
htmlContent: `Are you sure you want to Permanently Delete the Customer Setup for ${custLabel}?`,
ariaLabel: 'Delete Dialog'
}).then(() => { ...
this.notification.working = true
this.ezo.EDI_CUSTOMER.remove(this.currentId).then(() => {
this.primaryTab = 0
this.removeCustomerFromList(this.currentId)
this.currentId = 0
this.notification.working = false
}, error => {
this.notification.working = false
this.notification.showAlert({
title: "Error",
htmlContent: error
})
})
