How to use it:

1. Download the package and insert the minified version of the serializeFields plugin after jQuery.

<script src="/path/to/cdn/jquery.slim.min.js"></script>
<script src="/path/to/dist/jquery-serializeFields.min.js"></script>

2. Serialize your HTML form and return a JavaScript object.

<form id="example">
  <input type="text" name="username" value="my user name" />
  <fieldset data-name="address">
      <legend>Address</legend>
      <input type="text" name="street" value="654, test street" />
      <input type="text" name="country" value="Brazil" />
  </fieldset>
  <fieldset data-name="contact">
    <legend>Contact</legend>
    <input type="text" name="email" value="[email protected]" />
    <fieldset data-name="phones">
        <legend>Phones</legend>
        <input type="text" name="primary" value="+55 51 123456789" />
        <input type="text" name="mobile" value="+55 51 987654987" />
    </fieldset>
  </fieldset>
  <input type="checkbox" name="check1" value="true" checked/>
  <input type="checkbox" name="check2" value="true"/>
  <input type="checkbox" name="check3" value="true"/>
  <input type="submit" />
</form>

$("#example").submit(function(event) {
  var data = $(this).serializeFields();
  event.preventDefault();
});

3. Convert the JavaScript object into a JSON object using the JSON.stringify method.
