hi,I saw the php demo,though i don't understand php,but i guess the server process should add status and the status's value,then the error is gone.However,the success event just doesn't work

Hello,

Please move the success option outside of async:
async: {
},
success: onSuccess

I hope this helps.

Kind regards,
