Javascript Form Message
Jamroom Developers
You could use the .form_submit_box element and add your own div in there
function xxSomething_show_error_message(){
$('.my_error_message').remove();
$('.form_submit_box').prepend('<div class="my_error_message page_notice error">Some message before the SUBMIT button</div>');
}
Usually there will only be one form on a form page and only one submit button. This way would run into difficulties if there were more than one form on the page, only the first form would get the message.
If its on the skin side of things then thats open to customization so harder to have a fixed setup.
I don't think there is anything specific setup as a do-it-this-way guide on this subject.
