问题描述
我正在使用一个表单，我想向特定用户发送电子邮件提交表单后.我可以得到一个下拉列表员工姓名.我将从列表中选择任何名称.在选择特定名称，他的电子邮件ID或ID应该放在电子邮件按钮的值中，以便点击电子邮件时，我将直接在电子邮件按钮上获得他的电子邮件ID.
I am working with a form where I want to send email to a particular user after form submission. There is one dropdown list where I can get employee names. I will select any name from the list. On select particular name, his email id or id should go into the value of the email button, so that on click email, I will get his email id directly on the email button.
我是Angular的新手.请帮忙.
I am new to Angular. Please help.
<select ng-model="empInfo1" ng-options="emp.candidate_name for emp in names4" class="span2"></select>
<button type="button" class="btn btn-primary" ng-click="email()">Email</button>
推荐答案
您可以使用ng-model并通过ng-click传递模型，要获取所选电子邮件的按钮值，请使用角度表达式
You can have a ng-model and pass the model on ng-click, To get the selected email in button value , use angular expression
{{selected.email}}
演示
var app = angular.module('todoApp', []);
app.controller("dobController", ["$scope",
function($scope) {
$scope.names4 = [{
"candidate_name": "Thomas",
"email": "tford0@noaa.gov",
"id": "a35398ac-a974-47f6-9beb-ff9d5a6a8282"
}, {
"candidate_name": "Julie",
"email": "jhansen1@pen.io",
"id": "499e919a-e247-4665-9468-cc56a444848e"
}, {
"candidate_name": "Albert",
"email": "amason2@g.co",
"id": "76f53028-ec26-4b52-b12e-42ba3983ec36"
}];
$scope.email = function(selected) {
alert(selected.email)
}
}
