I do this on two of my plugins, flXHR proxy and mpAjax. These were the
two I talked about in my jQuery Conf talk on extending Ajax, and it
comes down to exactly this method, wrapping the $.ajax call.
But, one thing I would suggest, do this instead:
(function($){
var _ajax = $.ajax;
$.extend({
ajax:function(o){
if (this.data......
....
return _ajax.call(this,o);
}
});
})(jQuery);
I believe that's the more suggested way of extending/overriding
functions the "jQuery" way. Also, the ".call()" makes sure to preserve
the "this" binding for the original ajax call, which I think is a
safer way to deal with jQuery internals overriding.
