checkbox with jquery

how to Disable Text Fields When Checkbox Is Checked…?

Wrong room (salah kamar), perhaps?

Yii::app()->clientScript->registerScript('textfield-disabled', "

$('#checkbox').click(function(){

  if ($(this).is(':checked'))	

    $('#textfield').attr('disabled', true);		

  else

    $('#textfield').attr('disabled', false);

});

");

thanks

where do we put this? on model? or view?

View.
