This is not really an issue, because the code works, but I am just curious as to why it happens.

I have the following jQuery code for an ajax post:

$.post('./add_fee_row/<?php echo $date; ?>',post, function(data){ ... });

It all works fine and dandy.

However in the Chrome Console it says:

Why does it say cancelled?

Everything happened as if the post was successful. Why does it say that?

(the php server code is available if needed)

I am using Google Chrome version: 17.0.942.0

There was a bug in Chrome DevTools, it is already fixed: http://code.google.com/p/chromium/issues/detail?id=104920

回答2:

it may happen when Chrome sees that the actual data doesn’t match the headers.

If you return your answer with header type added, it shouldnt say canceled (Content-type: text/plain. for example)

You can check them by looking Event tabs - response headers.
