Чтобы контролировать события, я использую механизм публикации / подписки
jQuery.subscribe = function( eventName, obj, method ){
$(window).bind( eventName, function() {
obj[method].apply( obj, Array.prototype.slice.call( arguments, 1 ) );
});
return jQuery;
}
jQuery.publish = function(eventName){
$( window ).trigger( eventName, Array.prototype.slice.call( arguments, 1 ) );
return jQuery;
}
Вот пример его использования
// a couple of objects to work with
var myObj = {
method1: function( arg ) {
alert( 'myObj::method1 says: '+arg );
},
method2: function( arg1, arg2 ) {
alert( arg1 );
//republish
$.publish( 'anEventNameIMadeUp', arg2 );
}
}
var myOtherObj = {
say: function(arg){
alert('myOtherObj::say says: ' + arg);
}
}
// you can then have all your event connections in one place
//myObj::method2 is now listening for the 'start' event
$.subscribe( 'start', myObj, 'method2' );
//myOtherObj::say is now listening for the 'another' event
$.subscribe( 'anotherEvent', myOtherObj, 'say' );
//myObj::method1 is now listening for the 'anEventNameIMadeUp' event
$.subscribe( 'anEventNameIMadeUp', myObj, 'method1' );
//so is myOtherObj::say
$.subscribe( 'anEventNameIMadeUp', myOtherObj, 'say' );
// ok, trigger some events (this could happen anywhere)
$.publish( 'start', 'message1', 'message2' );
$.publish( 'anotherEvent', 'another message' );
