cakephp get element value js helper

Question

I am beginner to CakePHP and tried searching this question but no any gold. I have a select button and when user select an option I have to fire a event and pass the selected value to the controller's action. The code goes below:

<?php
//I only need a select button why to bother of creating form
echo $this->Form->input('district',array('label'=>'labelhere','id'=>'idhere'));

//script handler for select option
$this->Js->get('#idhere');
$this->Js->event(
        'change',
        $this->Js->request(
            array('action' => 'listing',<the selected value of #idhere here>),
            array('async' => true,
                'method'=>'POST',
                'update' => '#HFNames')
        )
    );

?>
<div id="HFNames">
Div to include ajax returns.
</div>

Precisely, What is the CakePHP equivalent for Jquery's $('selector').value();

Here is the Html code generated:

<html>
<div class="input select"><label for="idhere">labelhere</label><select  name="data[district]" id="idhere">
<option value="01">Bhojpur</option>
<option value="02">Dhankuta</option>
<option value="03">Ilam</option>
<option value="04">Jhapa</option>
<option value="05">Khotang</option>
<option value="06">Morang</option>
<option value="07">Okhaldhunga</option>
<option value="08">Panchthar</option>
<option value="09">Sankhuwasabha</option>
<option value="10">Saptari</option>
<option value="11">Siraha</option>
</select></div>
</html>

which html is generated by echo $this->Form->input('district',array('label'=>'labelhere','id'=>'idhere')); — user2193789

var_dump($this->request->data) in your function listing to see how data came.
