checking javascript and Isdefined tab

Question

I would like to have some client side javascript validate first then run a SQL stored procedure next, but only IF the javascript evaluates to true. Currenly, I have some code like:

<cfif IsDefined("Form.submit")>
run stored procedure
<cfelse>
show form
</cfif>

What's happening is my java is firing, but then the form runs the SP and I don't want that to occur UNLESS the java evaluates to true. I was just wondering if this is something syntactically I should do in the cold fusion side or in the javascript side?

Thanks,
Phil

I was able to get this to work. What I did was set a value in javascript of the submit button like this

document.Register.submit.value = "No"

I did this in the validation function of the javascript. Then I was able to read the value from cold fusion like this
<cfif #form.submit# NEQ "No" >

So I appreciate the attempts for help, but I got it.

I'm not sure how you are trying to do this, but it sounds like a classic
misunderstanding of how ColdFusion and JavaScript work together, in so
much as they *don't*. ColdFusion runs on the server and JavaScript runs
on the client and never do the two meet!

You can have ColdFusion deliver dynamic JavaScript to the client, the
same as it can deliver dynamic HTML.

You can have JavaScript make HTTP requests to ColdFusion resources.
With AJAX techniques you can even do this behind the scenes without
refreshing the browser.

But you can not have ColdFusion and JavaScript running together in any
truly, line by line, coordinated manner.
