Reading error values from ajaxError

I have added a JQuery error handler as follows:

		$( document ).ajaxError(function( event, request, settings ) {		  
		  alert("ERROR: event = " + event + ", request = " + request + ", settings = " + settings);
		});

Open in new window


However when I try to output the values I get [object Object] for each one. I simply want to output all the error information returned.

I know probably have to use the dot notation to extract the records but can someone refer me to a page where all the possible values are defined?

can you show a bit of your code to understand what object types are under event, request and settings ?

you would be probably interested most in
event.type
or
event.target

as per others, I'm not sure what they bear, so can't really tell what reasonable info could be gotten from them :)

hope this helps

OK thanks for this. I have looked around some more and have settled on the following:

		$( document ).ajaxError(function( event, jqxhr, ajaxOptions, errorThrown ) {		  
		  alert("ERROR: \nevent = " + event.type + "\njqxhr.status = " + jqxhr.status + "\najaxOptions.url = " + ajaxOptions.url + "\nerrorThrown = " + errorThrown);
		});

Next time just make sure you inspect the objects using any browser development tools.

Also console.log is more "friendly" than the alert and JSON.stringify(...) is sometimes useful to see the object structure as a string.

I found out what the other parameters contained in addition to the input from Radek.
