Where is onclick event function?

Question

I'm new to magento. I go through the Catalog->Manage Products module to understand the coding & design, i seen that everything (design and coding and controller actions) in block and controllers is there except submit button code?

can you anyone tell me where is the submit button design & code and how that button works?

if I added the custom action to perform that action where I write code?

thanks in advance.

Answer 1

this is something you can find around Mage_Adminhtml_Block_Widget_Grid class, check it's _prepareMassaction method. This is where that button comes from.

Specifically, for products grid page check out file app/code/core/Mage/Adminhtml/Block/Catalog/Product/Grid.php for better understanding.

This is specific part of code in that file that reflects as "Delete" item in dropdown on your screen:

    $this->getMassactionBlock()->addItem('delete', array(
         'label'=> Mage::helper('catalog')->__('Delete'),
         'url'  => $this->getUrl('*/*/massDelete'),
         'confirm' => Mage::helper('catalog')->__('Are you sure?')
    ));
