Response data from $.ajax request failure 1

[1DMF]

Hi,

I have an ajax request, I return the following...

print "Content-type: text/html\n";
print "Status: 400 Bad Request\n\n";
print $template->output;

But I cannot find the returned data anywhere in the ajax response

error: function(jqXHR){
            showDialog(jqXHR.responseText,'AJAX Failed');
        }

All that does is show me 'Bad Request'?

How do I get access to the actual returned HTML output from the 400 response?

Success works fine....

        success: function(data){
            showDialog(data,'AJAX Success');
        }

So where is the data stored in an 'error' return?

Thanks,
1DMF.

Why are you surprised at that when that is exactly what you send as the response?

 print "Status: 400 Bad Request\n\n";

User agents don't hang around waiting for more data after a HTTP: 4xx response is given.

So how do you fail an ajax request and pass back bespoke error messages?

I've given up as I don't seem to be getting any returned data if error code not a 2xx , so I've refactored my success to deal with 207 status code

success: function(data,status,jqXHR){  
        if(jqXHR.status === 207)
        {                         
            showDialog(data);
        }
        if(jqXHR.status === 200)
        {                         
            uploadComplete();
        }                                              
    }

It seem even when server side has failed , you have to return a 2xx status code if you want the Ajax to receive any result data (in this case bespoke error messages)

Send the appropriate error code and your status text.

User agents don't care what it says, they just want the correct number.

You could send

print "Status: 400 Don't be so damned stupid\n\n";

or

print "Status: 400 Hasta La Vista Baby!\n\n";

hmm, I tried that and got an error, perhaps because it was HTML and so malformed?

Send it as a header instead of a print.

Yes, I was... I think because I was wrapping a HTML template around the message which included a html header etc.. it was too malformed for a string message in the header output.

However, I have refactored the error handling...

print "Content-type: text/html\n";
print "Status: 400 $error_txt[$_[0]]\n\n";

And revamped the AJAX code...

        error: function(jqXHR,textStatus,errorThrown){
            showDialog(errorThrown,'AJAX Failed');
        }

It is now working as desired, so good to know I was on the right track.

Many thanks Chris, appreciated.
