Basic Usage:

1. Include both jQuery library and the jsForm plugin's script on the page.

<!-- jQuery -->
<script src="/path/to/cdn/jquery.min.js"></script>
<!-- Core -->
<script src="/path/to/src/jquery.jsForm.js"></script>
<!-- OPTIONAL. UI Controls and Field validation -->
<script src="/path/to/src/jquery.jsForm.controls.js"></script>

2. Define your form data in a JS object as follows:

var jsonData = {
    name: "jQueryScript", // standard inputs
    props: {
      active: true, // checkbox
      groups: [{
        name: "Base",
        priority: 0,
        tasks: [{ id:0, name: "base task1", priority: 1}, {id:1,name: "base task0", priority: 0}, {id:2,name: "base task2", priority: 2}]
      },
      {
        name: "Important",
        priority: 2,
        tasks: [{id:0, name: "imp task1", priority: 1}, {id:1,name: "imp task0", priority: 0}]
      },
      {
        name: "Other",
        priority: 1,
        tasks: [{id:0, name: "other", priority: 1}]
      }]
    },
    state: "VISIBLE"  // selects (enums)
};

3. Initialize the plugin and fill the HTML form with the data you just defined.

<div id="details">
  Name: <input name="data.name"/><br/>
  <input type="checkbox" name="data.props.active"/> active<br/>
  <select name="data.state">
    <option value="VISIBLE">visible</option>
    <option value="IMPORTANT">important</option>
    <option value="HIDDEN">hidden</option>    
  </select>
  <div class="collection sort" data-field="data.props.groups" data-sort="priority">
  <fieldset>
    <legend>Group: <span class="field">groups.name</span></legend>
    <ul class="collection sort reorder" data-field="groups.tasks" data-sort="priority">
      <li><input name="tasks.name"/></li>
    </ul>
    <button class="sortUp">up</button> <button class="sortDown">down</button> 
  </fieldset>
  </div>
</div>

$("#details").jsForm({
  data:jsonData
});

   */
  prefix: "data",
  /**

   * Disabling this will increase performance, but disabled the "changed" functionality.
   * This will add the given css class to changed fields.
   */
  trackChanges: "changed",
  /**

   * This is discouraged especially when you have tabs or similar elements in your form.

   */
  processors: null,
  /**
   * dataHandler will be called for each field filled.

      if(field.hasClass("reverse"))
        return val.reverse();
    }
  }*/
  /**

   * inputs with a span with the given field
   */
