[jQuery] Global AJAX handlers
Hi folks,
which of the following examples of global ajax handlers make more sense
and are easier to understand?
$("#msg").ajaxSuccess(function(){
$(this).append("Successful Request!");
});
or
$.ajaxSuccess(function(){
$("#msg").append("Successful Request!");
});
With chaining:
$("#msg").ajaxStart(function(){
$(this).show();
}).ajaxStop(function() {
$(this).hide();
});
or
var msg = $('#msg');
$.ajaxStart(function() {
msg.show();
});
$.ajaxStop(function() {
msg.hide();
});
Your opinion is appreciated.

Hi Jörn,
I like chaining most!
Although I think the following might make more sense anyway:
$.ajax({
...
stop: function() {},
start: function() {},
...
});
That way I have more control over which XHR requests are displayed.
There may be some that the user is not aware of and does not need to be
(validation, ping etc.)

Re: [jQuery] Global AJAX handlers
Well I think global should probably mean global and not attached to
anything but the jQuery object. Perhaps sometimes I don't want or need
to have an ajaxSuccess method be attached to a DOM node. The only way
I think having it like this:
$('#msg').ajaxStart(...
makes sense is if mutliple global handlers can be attached.

Re: [jQuery] Global AJAX handlers
I think the global responders should be attached to the jQuery object rather than to a DOM element. That said, it's very useful to be able to override the global responders for individual requests -- as Klaus points out, there are often XHR requests that don't merit the user's attention.

If you declare local handlers they are called in addition to the global methods, not instead of them. Mike ___ jQuery mailing list discuss@jquery.com http://jquery.com/discuss/

If you declare local handlers they are called in addition to the global methods, notinstead of them.MikeMike, I agree, right now there is no override mechanism. It would be pretty easy to add one though -- add an optional boolean argument (supressGlobalResponders or something) on the ajax function, and then check its value before invoking the global responders. You could then utilize a global responder for the common case (when the user needs feedback), but override the globals when the user doesn't need to be aware of the activity. ___ jQuery mailing list discuss@jquery.com http://jquery.com/discuss/

How about a "global" option for a ajax request? If true, global handlers are called, if false, they are not. Starting from the current behaviour, the default would be true. -- Jörn -- NEU: GMX DSL Sofort-Start-Set - blitzschnell ins Internet!

Re: [jQuery] Global AJAX handlers
Andre, Zörn, Those are both good ideas for overriding the global callbacks. I'd like that capability. Mike ___ jQuery mailing list discuss@jquery.com http://jquery.com/discuss/
