我想实现以下功能:
假设您有1个输入字段和2个下拉列表。在输入字段中,您可以填写您的电子邮件地址,然后您可以选择此电子邮件的类型(个人,专业,其他或任何内容)。
现在,在第三个下拉列表中,您将看到一个电子邮件列表,您可以从中选择您喜欢的电子邮件地址。
那会发生什么:
1)如果输入字段中没有任何内容,则首选电子邮件下拉列表为空(已经是这种情况)。
2)当电子邮件填写为AND TYPE时,首选电子邮件下拉列表应包含此值: test@test.com(个人)。
3)当有电子邮件填写但没有TYPE时,首选的电子邮件下拉列表应该包含以下值: test@test.com 例如没有类型
HTML:
<div ng-repeat="email in contactInfo.emails">
<input id="email" type="text" ng-model="email.email"/>
<select id="emailType" ng-model="email.emailTypeId" ng-options="emailType.id as emailType.name for emailType in emailTypes">
<option value="">Choose...</option>
</select>
</div>
<br/><br/>
<label>Preferred e-mail:</label>
<select style="margin-left: 20px; width: 50%;" id="preferred-email" ng-model="contactInfo.preferredEmail" ng-options="email.email for email in (contactInfo.emails | filter:filterEmail) track by email.id">
<option value="">Choose...</option>
</select>
JAVASCRIPT:
function MyCtrl($scope){
$scope.contactInfo = {};
$scope.emailTypes = [{"label":"Personal","id":1,"name":"Personal","rank":2},{"label":"Professional","id":2,"name":"Professional","rank":2},{"label":"Other","id":3,"name":"Other","rank":4}];
$scope.contactInfo.emails = [{"id":1100, "emailTypeId":2,"email":"member@test.com"}, {"id":1200, "emailTypeId":1,"email":"member2@test.com"}];
$scope.contactInfo.prefferedEmail = {};
$scope.filterEmail = function(email){
return (email.email);
}
}

HERE是小提琴,但只有第一个正在发挥作用。
我没有蚂蚁线索,所以如果有人可以帮助我,这将是很好的。谢谢你的时间。

以下是一个示例实现 - http://jsfiddle.net/iamgururaj/T7fkH/5/
代码:
<select style="margin-left: 20px; width: 50%;" id="preferred-email" ng-model="contactInfo.preferredEmail" ng-options="getEmail(email) for email in (contactInfo.emails | filter:filterEmail) track by email.id">
<option value="">Choose...</option>
</select>
JS:
$scope.contactInfo = {
emails: [{
"id": 1100,
"emailTypeId": "2",
"email": "1@test.com"
}, {
"id": 1200,
"emailTypeId": "1",
"email": "2@test.com"
}]
};
$scope.emailTypes = {
"1": "Personal",
"2": "Professional",
"3": "Other"
};
$scope.filterEmail = function (email) {
return (email.email);
}
$scope.getEmail = function (email) {
if (email.emailTypeId) {
return email.email + ' (' + $scope.emailTypes[email.emailTypeId] + ')';
}
return email.email;
}
