[jQuery] ajax Error

[jQuery] ajax Error


Hi, I am playing with ajax, the script works occasionaly but then
errors and activates the error callback function (as I would expect)
but how do I see what the actual error is. The manual says a second
var is passed to it but how do I read it?!
error: function(xhtml,error){
alert(error + "/n/nThere was a server error and your request could not
be completed.");
setError();
}
Should that do it? - If so all I'm being returned is 'error'.
Also can someone explain the statuses and how to use them. Generally
it all works perfectly but sometimes I get these unknown errors and I
really want to get to the bottom of them.
Thanks
Simon
