Javascript in S2
All,
What are my options if I want to use a confirm when a user clicks a
S2 anchor? Its an anchor that will remove something, so I want the user
to confirm that before the database gets touched. Currently the confirm
is not there, and when you click the anchor, the item is removed. No
bueno. Time to do it right.

I suppose that, simplistically, the logic flow would go something like
1) User clicks "Delete" which calls the delete() method on your action.
2) Your action does nothing except forward to confirmDelete.jsp
3) If the user clicks confirm then call a confirmedDelete() method in your
action that actually performs the deletion.
You could harden this by storing a flag in the session so that you can ensure
that confirmedDelete() cannot be called without going through delete() first.
If you needed confirmedDelete() functionality throughout your application, I
would look into the possibility of creating a custom interceptor to provide
this functionality.
However, I have no idea how to make your confirmDelete.jsp appear as a pop-up
window over the existing display. If anyone knows how to do this I'd be
eternally grateful

Musachy / Laurie,
Thanks for setting me straight. Working perfectly. Laurie, at a
high level, how would you use the backend to do this? I'd like to go
this way, but ive never done it before. Thanks for any input :)

You have to return "false" from that function in order to cancel the
submit. It is a javascript thing, as far as Struts is concerned,
anything you put into "onclick" will be passed outputted to the onclick
event in the generated html.

Laurie,
Thanks for the quick reply, but I have tried that. It does
display the confirm window, but the users approval/denial has no effect.
The record gets removed regardless. What am I missing? Im sure it's a
simple thing :)

Your options are the same as in any other HTML + Javascript context. At
simplest, use an onclick="javascript:confirm('prompt')" type construct.
You should really consider putting the guard logic server-side, though,
so it isn't bypassed if Javascript is disabled in the user's browser
(depending how critical the delete operation is).

Your options are the same as in any other HTML + Javascript context. At
simplest, use an onclick="javascript:confirm('prompt')" type construct.
You should really consider putting the guard logic server-side, though,
so it isn't bypassed if Javascript is disabled in the user's browser
(depending how critical the delete operation is).
