2. Get/set the value of an input field.

<input type="text" class="text-input" name="text">
<input class="text-value" type="text">
// Get
$('.text-value').xval($('.text-input').xval());
// Set
$('.text-input').xval($('.text-value').xval(), { 
  event: 'mychange', 
  args: ['test'] }
);
// event handler
$('.text-input').on('mychange', function(e, ...args) {
  console.info('mychange text', this, this.value, ...args);
});

3. Get/set the value of a group of radio buttons.

<label><input type="radio" class="radio-input" name="radio" value="1"> One</label>
<label><input type="radio" class="radio-input" name="radio" value="2"> Two</label>
<label><input type="radio" class="radio-input" name="radio" value="3"> Three</label>
<input class="radio-value" type="text">
// Get
$('.radio-value').xval($('.radio-input').xval());
// Set
$('.radio-input').xval($('.radio-value').xval());
// Event handler
$('.radio-input').on('change', function() {
  console.info('change radio', this, this.value);
});

4. Get/set the value of a group of checkbox inputs.

<label><input type="checkbox" class="checkbox-input" name="checkbox" value="1"> One</label>
<label><input type="checkbox" class="checkbox-input" name="checkbox" value="2"> Two</label>
<label><input type="checkbox" class="checkbox-input" name="checkbox" value="3"> Three</label>

$('.checkbox-input').xval($('.checkbox-value').xval().split(/\s*\,\s*/));
// Event handler
