If you don't want to redirect your form submitters after a submission or you want to add extra validation logic to your form then submitting with AJAX is a good option. Getform form endpoints accept standard AJAX requests and work cross-origin by default.

Basic AJAX Setup

Paste the example AJAX code below anywhere before the </body> tag of your HTML.

$("#ajaxForm").submit(function(e){
  e.preventDefault();
  var action = $(this).attr("action");
  $.ajax({
    type: "POST",
    url: action,
    crossDomain: true,
    data: new FormData(this),
    dataType: "json",
    processData: false,
    contentType: false,
    headers: {
      "Accept": "application/json"
    }
  }).done(function() {
     $('.success').addClass('is-active');
  }).fail(function() {
     alert('An error occurred! Please try again later.')
  });
});

Note: If you want to get your responses in JSON format, you need to add dataType: "json" , it sets Accept Http Header to application/json

Then give "ajaxForm" ID to your HTML to relate form with your JQuery AJAX Setup.

<form id="ajaxForm" action="https://getform.io/f/{your-endpoint}" method="POST">

    <input type="text" name="name" id="name">
    <input type="email" name="email" id="email">
    <input type="text" name="message">
    <button type="submit">Send</button>

</form>

Uploading Files with AJAX

In order to accept file uploads with AJAX, you simply have to add contentType="multipart/form-data" to your JQuery code and make sure that your HTML code includes <input type="file" name="file">.

$("#ajaxForm").submit(function(e){
  e.preventDefault();
  var action = $(this).attr("action");
  $.ajax({
    type: "POST",
    url: action,
    crossDomain: true,
    data: new FormData(this),
    dataType: "json",
    contentType: "multipart/form-data",
    processData: false,
    contentType: false,
    headers: {
      "Accept": "application/json"
    }
  }).done(function() {
     $('.success').addClass('is-active');
  }).fail(function() {
     alert('An error occurred please try again later.')
  });
});
