如何使用Node JS和Mailgun发送联系人电子邮件？

Question

new to node js and mail gun. I am trying to send a 'contact us' email from a website that is using the following for my send button (on my index.html page).

      <!-- START CONTACT SECTION -->
    <section class="section-contact" id="contacts">
        <div class="container">

            <!-- START SECTION HEADER -->
            <h2 class="reveal reveal-top">Contact Us</h2>
            <div class="subheading reveal reveal-top">
                Hit us up.  Let us know how we can make things better ( <b>Support@mail.com </b>).  
            </div>
            <!-- END SECTION HEADER -->

            <div class="contact-form-wrapper reveal reveal-bottom">

                <!-- START CONTACT FORM -->
            <!--    <form method="POST" action="./scripts/writeus.php" accept-charset="UTF-8" class="contact-form" id="jvalidate" novalidate="novalidate"> --> 
               <form method="POST" action="./scripts/mailgun.php" accept-charset="UTF-8" class="contact-form" id="jvalidate" novalidate="novalidate">

I have Node.js with Express and mailgun installed and working on my local machine with the snippet bellow hard coded as a test in my server.js

var Mailgun = require('mailgun').Mailgun;

var mg = new Mailgun('some-api-key');
mg.sendText('example@example.com', 'Recipient 1 <rec1@example.com>',
  'This is the subject',
  'This is the text',
  'noreply@example.com', {},
  function(err) {
    if (err) console.log('Oh noes: ' + err);
    else     console.log('Success');
});

How do I get the button info and send from my index.html ?

Thanks for the help. Much appreciated.

You need create web server to receive submit from your form or ajax call. Look this: http://expressjs.com/

example:

var express = require('express');
var Mailgun = require('mailgun').Mailgun;
var app = express();

app.post('/sendMail', function (req, res) {

   /*use body-parser (https://github.com/expressjs/body-parser) for parameters */  
   var mg = new Mailgun('some-api-key');
   mg.sendText('example@example.com', 'Recipient 1 <rec1@example.com>',
         'This is the subject',
         'This is the text',
         'noreply@example.com', {},
      function(err) {
         if (err) {
           console.log('Oh noes: ' + err);
           res.send('Error occurred');
         }
         res.send('Email sent');
       });

app.listen(3000, function () {
   console.log('Example app listening on port 3000!');
});
