Empty Recycle Bin using java script
With SharePoint User level recycle bin(that is displayed in Quick Launch), there is no way to ‘Empty’ the recycle bin in a single go. We have this option in Site Collection Recycle Bin. May be this is done deliberately to prevent users from deleting all items by accident! This is definitely a fallback from developers perspective.
A way to Empty the recycle bin without going through the pain of manually deleting each of the files or selecting the files and clicking on the ‘Delete Items’ button.
· Open your SharePoint Recycle Bin Page by clicking on the Recycle Bin icon on the Quick Launch.
Be careful as all of the items will not be to sent to Site Collection Recycle Bin. This a good tip for development phase.
