Confirming a user's action

If you have links whose action is irreversible and you want to make the user confirm what they are doing then you could use the JavaScript onclick event.

The HTML to invoke this is:

<a href="../ViewName/DocID?DeleteDocument" onclick="return confirm('Are you sure you want to delete this document?');">Delete Document...</a>

The onClick event will return either of two values depending on whether the user clicks 'Ok' or 'Cancel':

true - the link should be opened;
false - do not be opened;
