Thank you.
I tried to use
$(‘#CompanyForm’).jqxValidator(‘validate’, function (result) {
alert(result);
} );
The problem still exists. if I do not use ajax to check the company name. It is ok. Only if I add ajax function, when I input everything needed,the ‘validate’ function does not executed. Is anything wrong with my ajax function. By the way, the check of company name works properly. But seems no signal send back to call the ‘validate’. If I change the ‘commit(true)’ to ‘return true’, the check company name won’t work.
