Checkbox Component — fgta5js Documentation

Overview

Inheritance Notice: Class Checkbox inherits all of its core state tracking, validation logic, editing mode configurations, and event handlers from the abstract base class Input.

The Checkbox class wraps standard HTML checkbox elements within the fgta5js framework, adding custom styled representations, unified checked/unchecked event listeners, and automated change tracking.

HTML Markup

Define standard checkboxes in HTML. Mark the type as checkbox and add fgta5-component="Checkbox".

<form id="myform" locked="true">
  <!-- Checkbox Input -->
  <div class="demo-input-field" field="is_disabled">
    <label for="is_disabled">Account Is Disabled</label>
    <input id="is_disabled" fgta5-component="Checkbox" type="checkbox">
  </div>
</form>

Initialize and render the form in JavaScript:

const form = new $fgta5.Form('myform');
form.render()
