How create select all checkbox in Yii

Question

I have a checkboxlist using CHtml::checkBoxList and I need a checkbox with 'Select all' to select all checkboxes when it is checked. But I don't know how to do it.

Answer 1

You could do

<?php echo CHtml::checkBox('select_all',false, array('onclick' => "js:if($(this).is(':checked')) {$('.example').attr('checked','checked');}else{$('.example').removeAttr('checked');}")) ?>
<?php echo CHtml::activeCheckBoxList($model, 'items',array('example1','example2','example3'), array('class'=>'example')) ?>
