disable select in cakephp

Navigation
1

I have 2 selects, and I want to make that when one of the select is with an option other than empty, the other select goes into disable.

Follow my code: 

<script type="text/javascript">
 function handleSelect() {
 if (this.value == '30') {
     document.getElementById('agente_id').disabled = true;
 } else {
     document.getElementById('agente_id').disabled = false;
 }
 }
  </script>
  <div class='container'>
<form method="get" action="/financeiro/gerar_relatorios">
<div class='panel panel-primary'>        
    <div class='panel-heading'><B>FILTRAR COMISSÕES POR PERÍODO</b></div>        
    <div class='panel-body'>       
        <div class='row'>
            <div class='col-xs-6'>
                <?= $this->Form->input('data_inicio', array('class' => 'form-control mask_date','value'=> @$_GET['data']['data_inicio'])); ?>
            </div>
            <div class='col-xs-6'>
                <?= $this->Form->input('data_fim', array('class' => 'form-control mask_date','value'=> @$_GET['data']['data_fim'])); ?>
            </div>
        </div>
        <div class='row'>
            <div class='col-xs-6'>
                 <?= $this->Form->input('colaborador_id', array('class' => 'form-control','empty'=>'Filtrar todos colaboradores','value'=> @$_GET['data']['colaborador_id'])); ?>
            </div>
            <div class='col-xs-6'>
                 <?= $this->Form->input('agente_id', array('class' => 'form-control','empty'=>'Filtrar todos agentes','value'=> @$_GET['data']['agente_id'])); ?>
            </div>
        </div>
        <div class='row'>
            <div class='col-xs-6'>
                 <?= $this->Form->input('compra', array('class' => 'form-control','placeholder' => 'Filtre pelo número da compra','value'=> @$_GET['data']['compra'])); ?>
            </div>
        </div>
    </div>        
    <div class='panel-footer'>
        <?= $this->Form->submit('Filtrar', array('class' => 'btn btn-info')); ?>
    </div>        
</div>
</form>

My question is, how to instantiate this js function in select?

Try this: 

<?= $this->Form->input('compra', 
                    array('class' => 'form-control',
                          'placeholder' => 'Filtre pelo número da compra',
                          'value' => @$_GET['data']['compra'], 
                          'onchange' => "handleSelect(this);")
                   ); ?>

is there a better way to check how many inputs have been checked? Elaborate table of the MySQL database
