问题
I am writing one Web Application using XUL. In that Iam using AJAX XMLHttpRequest Object for sending request to server. When I use GPRS connection to send the request to the server from my web application the request is not going, but readyState has changed to 4 and status=0. If the request is not going out how the readyState is Changing.
The same Code working fine in local network. If I send the request to server from the browser using GPRS it is working fine. Can any body help me out in solving this problem.
Thanks in Advance.
回答1:
the request is not going
How do you determine that?
Do you use the HTTP scheme? If so, status == 0 is an issue, (google says there are known quirks in Firefox).
status == 0 is also returned when the request is using a non-HTTP protocol. So if you're making a file:// request accidentally, it would explain all the symptoms...
[edit 2009-09-07] Also found this issue: https://bugzilla.mozilla.org/show_bug.cgi?id=488605 aborted XMLHttpRequests have status==0 since Firefox 3.
[edit] I'm not /quite/ sure, but I think that cross-domain requests that are not allowed also end up with status == 0.
