JQuery ajax call default timeout value

Question

I got a bug report that I can't duplicate, but ajax-call timeout is the current best guess.

So I'm trying to find out the default value for timeout of a jQuery $.ajax() call. Anybody have an idea? Couldn't find it in jQuery documentation.

Thanks in advance, Marcus

Answer 1

There doesn't seem to be a standardized default value. I have the feeling the default is 0, and the timeout event left totally dependent on browser and network settings.

For IE, there is a timeout property for XMLHTTPRequests here. It defaults to null, and it says the network stack is likely to be the first to time out (which will not generate an ontimeout event by the way).

As an aside, when trying to diagnose a similar bug I realised that jquery's ajax error callback returns a status of "timeout" if it failed due to a timeout.

Here's an example:

$.ajax({     url: "/ajax_json_echo/",     timeout: 500,     error: function(jqXHR, textStatus, errorThrown) {         alert(textStatus); // this will be "timeout"     } }); 

Here it is on jsfiddle.
