You'd have to add some hidden form fields to
your form, have JS to populate these fields and submit the form, then use
the form fields to perform the duplicate search.
Or use WDDX (www.openwddx.org) <cfwddx> it allows
you to pass variables from JS to CF and vice versa (plus more)...

Hi,
I'd like to search duplicates in the database before submit the form. The
question is how can I pass _javascript_ variables to a SQL query. CF complaints
(variable y is not defined) if I use it directly:
y = document.AddNewItem;
// search existing
items in whole database
<CFQUERY NAME="qSearchDuplicates"
DATASOURCE="#request.app.dsn#"
BLOCKFACTOR="100">
SELECT
HardwareAddr,IPAddr,SERIALNUMBER,ASSETNUMBER
FROM
tblPrinter_inventory
WHERE
<CFIF y.ASSETNUMBER.value IS NOT
"">
AND (tblPrinter_inventory.ASSETNUMBER
=
'y.ASSETNUMBER.value')
</CFIF>
<CFIF
y.HardwareAddr.value IS NOT "">
AND
(tblPrinter_inventory.HardwareAddr =
'y.HardwareAddr.value')
</CFIF>
<CFIF
y.IPAddr.value IS NOT "">
AND
(tblPrinter_inventory.IPAddr =
'y.IPAddr.value')
</CFIF>
<CFIF
y.SERIALNUMBER.value IS NOT "">
AND
(tblPrinter_inventory.SERIALNUMBER =
'y.SERIALNUMBER.value')
</CFIF>
</CFQUERY>
if
(qSearchDuplicates.recordcount == 0)
{
y.submit();
}
else
{
alert("Printer with the same either Hardware or IP
Address, Serial or Asset number already exists in the Inventory
database.\n\nPlease check the details and try
again.");
return false
}
Thanks,
George ---
