What\'s the best way to trigger errors on elements for server-side validation errors that come back after the form passes the initial client-side validation?

Answer 1

On submit of the form, I would make the target of the form an invisible iframe on the page which would then call a function in the topWindow with it's result.

then in the page in the iframe call a javascript method in the top window that either redirects on success or displays the errors.

In the iframe

In the top window (as an example)

function uploadComplete( result ){
    $.unblockUI();
    if(result == "OK"){
        $.blockUI({ message: "File upload successful, request submitted.

Redirecting..." }); 
        setTimeout(function() { 
            $.unblockUI({ 
                onUnblock: function(){ window.location='thankyou.php'; } 
            }); 
        }, 2000);

    } else {
        $.blockUI({ message: "Failed.

"+result }); 
        $('.blockOverlay').attr('title','Click to remove').click($.unblockUI);
    }
}
