[jQuery] Immediate validation

[jQuery] Immediate validation


Hello jQuery Team:)
Sorry for banal question, but I have not found answet to it in the
web.
So, I have simple html form and I want to validate it using jQuery
validation plugin. Everything is fine? but I want to change validation
event. In documentaion it is said that,
"
By default, forms are validated on submit, triggered by the user
clicking the submit button or pressing enter when a form input is
focused (option onsubmit). In addition, once a field was highlighted
as being invalid, it is validated whenever the user types something in
the field (option onkeyup). When the user enters something invalid
into a valid field, it is also validated when the field loses focus
(option onblur).
"
Can I change it to make validation immediate, for example "onchange"
event + on submit?
I was trying to configure jQuery like this :
"
$j(document).ready(function(){
$j("#bookForm").validate({
         defaults: {
            immediate: true
        },
     event: 'change',
     onsubmit: true,
     rules: {
     title: {
         required:     true,
         maxLength:     <c:out value='${BOOK_TITLE_MAXSIZE}' />
     },
....
"
but it doesnt works for me.
Please, advise
Thanks,
Taras
