A team member put this into our project

$(function() {
    $("body").bind("ajaxError", function(event, XMLHttpRequest, ajaxOptions, thrownError){
        alert(thrownError);
    });
}

However I want to supress one of my errors (as it would be noise and verification isn't needed)

function blah() {

    ...

    errFunc = function(event, xhr, opts, errThrown) {
        //what could I do here?
        //event.stopImmediatePropagation()?
    }

    $.ajax({
        url        : '/unimportant_background_refresh',
        type       : 'GET',
        data       : { },
        dataType   : 'json',
        success    : updateBackgroundStuff,
        error      : errFunc,  // Suppresses error message.
    });

}

How can I stop the catch all error from happenning please? Can I just do something in the error function such as { event.StopPropogation(); } or must I work out some mechanism for having the catch all selectively ignore things please?

Global events can be disabled, for a particular Ajax request, by passing in the global option, like so:

 $.ajax({
   url: "test.html",
   global: false,
   // ...
 });

Taken from: http://docs.jquery.com/Ajax_Events

I would just throw a boolean into your code that's defaulted to false. Set it to true the first time the error is thrown and make sure to check for true at the start of the error function.

Something like:

function blah() {
    var errorHappened = false;

    ...

    errFunc = function(event, xhr, opts, errThrown) {
        if (errorHappened)
            return;

         errorHappened = true;

         // handle the errror.

    }

    // the rest of your code

}
