Magento - Get variable from grid to admin controller

My question is about,

how to get a variable from a Magemto grid to My admin controlle开发者_如何转开发r page. (ie Exactly to my public function massStatusAction())

Thanks.

You can get those ID like this

$productIds = (array)$this->getRequest()->getParam('product');

Where product is set as Mass Action field in the Grid's protected function _prepareMassaction() like this.

$this->setMassactionIdField('entity_id')

Hope this helps!
