How to check for a button

Question

I have a form that submits to itself. My submit is the
standard :
<input type="submit" name="btnsubmit" value="Submit Your
Order">
When the form is submitted, I check for the existence of
btnsubmit using paramerexists or isDefined :
<cfif parameterexsits(btnsubmit)>
perform inserts, etc.
</cfif>
This works fine. But my question is what do I do if the
type=button instead of submit ? For example
<input type="button" name="btnSubmit" value="Submit Your
Order">
I have some javascrpt validation that will submit the form
when the button is clicked. Howver, how do I determine whether the
button was seleceted or not, so that I can do my processing
(insert, etc. ) ? I tried to use the isDefined or parameterexists
like before but that does not work ?
What is the command to check that a button was selected
?

Answer 1

Assuming your <input> button is inside of the form you
are submitting,
simply use
<cfif isDefined('form.btnSubmit')>
However - some browsers only pass the button value if that
particular
button is clicked.
In other words, hitting 'enter' in another field of the form
may not
pass in the submit button value as part of the form scope. In
this case
you'd want to check for another one of the form variables,
ideally a
required field.
