我有一个表格来添加/更新一封或几封电子邮件。第一个电子邮件字段是强制性的。填写该字段后，可以单击“添加电子邮件”以添加新的电子邮件地址。通过这种方式，可以添加其他 4 封电子邮件（总共 5 封电子邮件）。
系统可以验证电子邮件的格式是否正确，并在必要时显示消息并将数据注册到数据库中。
这是我的观点（manageContact.html）

对于添加联系人，一切正常，并且电子邮件已正确注册。对于更新联系人，我对联系人的电子邮件有疑问。为了查看联系人的所有注册电子邮件，每次注册电子邮件以查看数据时，都需要使用我当前的脚本单击“添加电子邮件”按钮。如果电子邮件存在于数据库中，我想显示它们 - 所以每次显示行（字段+数据）。如果它不存在，则需要单击添加新电子邮件的按钮。
您能否帮我更新此代码，因为我不能直接在 ng-switch 中执行此操作？
这里我的控制器“ctrlEditContacts”和模块（app.js）：
var app=angular.module('ContactsApp', ['ngRoute', 'ui.bootstrap', 'ngDialog']);
app.factory('HttpInterceptor', ['$q', '$rootScope', function($q, $rootScope) {
return {
......
}
};
app.config(function($routeProvider, $httpProvider, ngDialogProvider){
$httpProvider.defaults.cache = false;
if (!$httpProvider.defaults.headers.get) {
$httpProvider.defaults.headers.get = {};
}
$httpProvider.defaults.headers.get['If-Modified-Since'] = '0';
$routeProvider.when('/add-contacts',
{
templateUrl: 'template/manageContact.html',
controller: 'ctrlAddContacts'
})
.when('/edit-contacts/:contactId',
{
templateUrl: 'template/manageContact.html',
controller: 'ctrlEditContacts'
})
.otherwise({redirectTo:'/all-requests'});
});
app.controller('ctrlAddContacts', function ($scope, ContactService){
$scope.title="Add a contact";
// Allow to create several fields EMAIL
$scope.emails = [
{
}];
$scope.log = function() {
console.log($scope.emails);
};
$scope.add = function() {
var dataObj = {email:''};
$scope.emails.push(dataObj);
}
$scope.submitForm = function(contact){
if($scope.ContactForm.$valid){
// Send the object to the backend for saving data
ContactService.addNewPerson(contact).success(function(Person){
$scope.ContactForm.$setPristine();
$scope.contact= Person;
});
}
}
});
app.controller('ctrlEditContacts', function ($scope, $routeParams, MyTextSearch, ContactService, ngDialog, $timeout){
//FOR ALLOWING SEVERAL EMAILS
$scope.emails = [
{
}];
$scope.log = function() {
console.log($scope.emails);
};
$scope.add = function() {
var dataObj = {email:''};
$scope.emails.push(dataObj);
}
$scope.contact={};
if($routeParams.contactId){
$scope.title="Edit the contact";
}
ContactService.loadPersonById($routeParams.contactId).success(function(contact){
$scope.contact.ID = contact[0].ID;
$scope.contact.EMAIL = contact[0].EMAIL;
$scope.contact.EMAIL_1 = contact[0].EMAIL_1;
$scope.contact.EMAIL_2 = contact[0].EMAIL_2;
$scope.contact.EMAIL_3 = contact[0].EMAIL_3;
$scope.contact.EMAIL_4 = contact[0].EMAIL_4;
})
.error(function (data, status, header, config) {
console.log("Query loadPersonById ERROR");
console.log("status:" + status);
if (status==302) {
alert("Session expired - New Authentication requested");
}
}).finally(function() {
});
$scope.submitForm = function(contact){
if($scope.ContactForm.$valid){
ContactService.updatePerson(contact, $routeParams.contactId).success(function(){
alert('Person updated successfully');
})
.error(function (data, status, header, config) {
})
.finally(function() {
});
}
};
});
这是我的工厂（appService.js）
app.factory('ContactService', function($http){
var factory={};
factory.addNewPerson=function(objContact){
return $http.get('http://myapp/contacts.cfc?method=addNewPerson&jsStruct=' + JSON.stringify(objContact))
};
factory.updatePerson=function(objContact,id){
var params = {
method: "updatePerson",
contactid: id,
jsStruct: objContact
};
var config = { params: params };
return $http.get('http://myapp/contacts.cfc', config)
};
return factory;
})
如果您有比 ng-switch 更好的解决方案，请告诉我。
预先感谢您的帮助。
