I found another way of doing it that is rather sneaky. Maybe someone
else will find it useful. I pull out liveHandler and make my own
live.add function.
var liveHandler = null;
(function(){
var add = jQuery.event.add;
jQuery.event.add = function(el, event, handler, data){
if(data.selector == "stealing" && !event)
liveHandler = handler;
else
add.apply(this, arguments)
}
var f = function(){}, d = {selector: "stealing"}
jQuery.event.add(document, "live",f,d);
jQuery.event.remove(document, "live",f,d);
jQuery.event.add = add;
})();
//hack live to provide what we need
jQuery.event.special.live.add = function( proxy, data, namespaces,
live ) {
jQuery.extend( proxy, data || {} );
proxy.guid += data.selector + data.live;
data.liveProxy = proxy;
jQuery.event.add( this, data.live, liveHandler,
data );
}
