Hey all,
How does a web app know when an XHR is rejected because of lack of funds?
In the catch block of:
try {
var xhr = new XMLHttpRequest( props_for_request );
...
xhr.send( JSON.stringify( {'items': items_to_send } ) );
...
} catch (err) {
...
}
I am currently getting the error :
[Exception... "Failure" nsresult:"0x80004005 (NS_ERROR_FAILURE)"
location: "JS
frame::app://6e9ae3f8-4f4e-8243-8087-4b1a2015c199/app.js::send_items::line381"
data:no]
I currently suspect that this is due to a zero balance which blocks the
use of the cell phone data channel.
Is this error the most detailed information available to the web app for
such a case?
Is the "data:no" at the end a canonical indicator that the use of the
data channel has been refused?
Is there any way to know that the refusal was due to lack of funds
(versus badly configured data channel or other reasons)?
I'd like to help the users by transforming that error into a more
helpful prompt but to do so I wanted to get a sense of the scope of
these kinds of errors sent to a web app.
thanks,
~adrian
