Re: Validation after HREF link clicked

[<Matt.Haas@xxxxxxxxxxx>]

You should hide the link (or at least not put the anchor tag around it)
if someone can't see what's behind it. You should also check when the
detail page is generated to make sure they are allowed to see it. You
could use JavaScript to keep the link from working but that's a lot of
extra work and not good from a usability standpoint.

Subject: [WEB400] Validation after HREF link clicked

Is there a way to do some validation after the user clicks a link but
before
the browser opens the link?

What I want to do is show a list of "items".  Each "item" has a link to
a
detail view about that "item".  While the list is being built, I will
flag
each "item" if the user is authorized to view the detail for each
"item".
When the user clicks the detail link, I want to check the flag to see if
they are authorized.  If they are, show the detail, if not, show a
message
box.

Is there a way a way for JavaScript or something else to be executed
when
the link is clicked?

TIA.
