Just incase pastie service goes offline in the future, i paste the
code below for future references.
function ajaxRespondToReadyStateWrapper(orig, readyState) {
var state = Ajax.Request.Events[readyState];
var response = new Ajax.Response(this)
if (state == 'Complete') {
try {
// GLOBAL RESPONSE VALIDATOR CODE HERE
} catch (e) {
this.dispatchException(e);
}
}
orig(readyState);
}
Ajax.Request.prototype.respondToReadyState =
Ajax.Request.prototype.respondToReadyState.wrap
(denajaxRespondToReadyStateWrappereme);
