Custom validation using get/post callback

[ettemlevestParticipant]

Hi!

I’m trying to build a custom validation rule to check that the entered serial number is already in use in my server-side database or not. On a blur event I want to start a $.post callback to check the input’s actual value. If it is in the database I want to display an error message to warn the user about the problem. Also when a submit event is fired I want to check this with the ‘validate’ method of jqxValidator if possible.
Thinking about this I can’t use jqxValidator’s custom rule function because if I put a $.post function in it, it will finish before the post returns any value. How can I display this custom message to warn the user and also has the form’s validator to return a false value if the number is in use? Is it possible with jqxValidator?

Thank you for your help,
Imre

Hi Imre,

There’s a sample which shows how to use jqxValidator for performing server validation – http://www.jqwidgets.com/jquery-widgets-demo/demos/php/registration_form.htm?arctic

Hope this helps.
