IsDefined() ? 1

[FALCONSEYE]

i have the following

<input type="image" name="delete" src="btn_delete_a.gif" onClick="return confirm('Are you sure to delete this spot?');">

on the action page, when i try to check and see if this image is clicked, i get nothing.
<cfif IsDefined('form.delete')>
defined
<cfelse>
undefined
</cfif>

moreover, when i <cfdump> the form values, i do not see this
'delete' under FORM.FieldNames.
what can i do to check if this image is clicked?
thanks for the help in advance...

if you're going to be putting an event in that will confirm something you shouldn't do it onclick, you should do it onsubmit.

you should also show your whole form...

It's probably better to create a hidden form field and set its value when the user clicks on your image. Apparently different flavors of browser treat image type values differently; see

http://groups-beta.google.com/group...nput+type=image&rnum=4&hl=en#2941e18455cf9aa1

for an interesting discussion about this.

That said, try inserting a value attribute in the tag.

When an image is clicked to submit a form, the image field is not passed with the form, but two fields called "X" and "Y" are, if I recall correctly (maybe "delete.X"). If your "delete" image is the only image that can be used, you could try checking for those fields.

However, what I have found to work better is something more like this:

<a href="/deleteitem.cfm?id=72828"><img src="/images/delete.gif" border=0></a>

--OR--

<a href="javascript:if(confirm('Are you sure?'))location.href='/deleteitem.cfm?id=72828';"><img src="/images/delete.gif" border=0></a>

... and just not even worry about incorporating delete ability into the same form. Do your deletion on a separate page from your other processing. You can also do this with an input type="button" and onClick="location.href, etc.

Joe, yes you are right. I didn't see the delete.X and delete.y fields in the <cfdump> at first. after i did a
<cfif StructKeyExists(FORM, 'delete.X')>
defined
<cfelse>
undefined
</cfif>

it works just like how i wanted.
also, this works like a charm

<input type="image" name="delete" src="btn_delete_a.gif" onClick="return confirm('Are you sure to delete this spot?');">

thanks ...
