in your controller:
render :json => { :errors => @example.errors.full_messages }, :status => 422
in your js file:
$('.form_id_or_class').live('submit', function() {
$.ajax({
url: $(this).attr("action"),
type: "POST",
data: $(this).serialize(),
success: function(data) {
// do some action
}
,error: function(xhr){
var errors = $.parseJSON(xhr.responseText).errors
}
});
return false;
});
