Hello!
Thanks you your answer, but it seems like it didnt help!
function pnrexists(a){
$.ajax({
async: true,
url: '/inc/chkusr.php?q=p',
type: 'POST',
dataType: 'html',
data: {'pnr': a},
timeout: 2000,
success: function(data) {
if(data==1){
alert('true');
return true;
}else{
return false;
}
}
});
}
$.validator.addMethod("pnrcheck", function(ph, element) {
if(persnr(ph)) {
alert('1');
if(pnrexists(ph)) {
alert('2');
I see:
alert 1 and alert true
setting the async to false dont seems to help either!
Any idea?
