Limiting ‘out-of-items’ to cart

The requirement is ‘out-of-stock’ items should not be added to the cart. By using the client script this can be achieved. So ‘out-of-stock items will not be added to the cart from any pages.

clientscript 1.0

/**
 * Script Description
 * This script will update the item line based on promotion
