How to make use of it:

1. Add the CSS class ‘data’ to type fields as follows:

<div id="form">
  <h1 class="title">Form</h1>
  <label class="label">
  <input class="input data" name="username" type="text" worth="formsjs_" />
  <label class="label">
  Send me promotional emails
  <br />
  <input class="checkbox data" name="allow_promotional_emails" type="checkbox" />
  <br />
  <label class="label">
    <br />
    <div class="select control">
      <select class="data" name="gender">
        <option selected value="unknown">Prefer not to say</option>
        <option value="other">Other</option>
        <option value="female">Female</option>
        <option value="male">Male</option>
  <label class="label">
    Where do you live?
    <br />
    <div class="select control">
      <select class="data" name="zipcode">
        <option value="">Elsewhere</option>
        <option value="94016">San Francisco</option>
        <option value="94088">San Jose</option>
  <div class="control">
    <label class="label">
    Account Type
    <label class="radio">
    <input class="data" checked type="radio" name="account_type" value="free" />
    Free Account
    <label class="radio">
    <input class="data" type="radio" name="account_type" value="premium" />
    Premium Account

2. Convert subject values right into a JSON object:

function submit() {
  let username = document.querySelector("[name=username]");
  let result = FORMSJS.readForm("#form");
  // Make the username box turn red if its length is less than 8
  if (username.value.length < 8) 
Array.from(document.querySelector("#form").getElementsByClassName("data")).forEach((element) => );

3. The JSON object needs to be like these:

  "username": "formsjs_",
  "allow_promotional_emails": false,
  "gender": "unknown",
  "zipcode": null,
  "account_type": "free"
