Just done some refining of the code. This will work, as long as you are
holding the validation results in a Query.
THe previosu version doesn't work because I was assuming that Item2 was an
object, but its not its a literal.
<script Language="JavaScript" type="text/javascript">
function Check_Items(Item1,Item2){
if (Item1.value!='')
return;
if (Item1.value!=Item2){
alert ("These contradict the DB")
Item1.focus();
}
return;
}
</script>
<cfoutput>
<input type="text" name="X" value=""
onblur="Check_Items(X,'#MyQuery.MyField#');">
</cfoutput>

Subject: Is this possible?
Hey all,
Is it possible to determine what a user has inputted in a form BEFORE the
form is submitted? What I would like to do is IF a user makes a selection in
the form that conflicts with information already in the db, I want to have a
javascript popup alert them to the discrepancy and have them verify if they
want to continue. Otherwise, just a regular submit button would be
displayed.
I have the javascript alert/confirm working alright, but I can't figure out
how to get it to check the formfields and only display conditionally. I
don't even think this is possible, considering that CF is server-side and
essentially what I want to do is have CF determine what was selected BEFORE
it is submitted. Is there a way I can determine this with JavaScript (I'm
not very good at JS, so "baby steps", please ;).
I know I could do this within CF and just have the form submit to an interim
confirmation page, but I would rather do this on the client.
Thanks!
Terri
