хм.. делал по примеру, но все-таки не работает:
Event = (function() {
var guid = 0;
function fixEvent(event) {
event = event || window.event;
if ( event.isFixed ) { return event }
event.isFixed = true
event.preventDefault = event.preventDefault || function(){this.returnValue = false}
event.stopPropagation = event.stopPropagaton || function(){this.cancelBubble = true}
if (!event.target) { event.target = event.srcElement }
if (!event.relatedTarget && event.fromElement) { event.relatedTarget = event.fromElement == event.target ? event.toElement : event.fromElement; }
return event
}
function commonHandle(event) {
event = fixEvent(event);
var handlers = this.events[event.type];
for ( var g in handlers ) {
var handler = handlers[g];
var ret = handler.call(this, event)
if ( ret === false ) {
event.preventDefault();
event.stopPropagation();
}
}
}
return {
add: function(elem, type, handler) {
if (elem.setInterval && ( elem != window && !elem.frameElement ) ) {
elem = window;
}
if (!handler.guid) { handler.guid = ++guid }
if (!elem.events) {
elem.events = {};
elem.handle = function(event) {
if (typeof Event !== "undefined") {
return commonHandle.call(elem, event)
}
}
}
if (!elem.events[type]) {
elem.events[type] = {};
if (elem.addEventListener) elem.addEventListener(type, elem.handle, false)
else if (elem.attachEvent) elem.attachEvent("on" + type, elem.handle)
}
elem.events[type][handler.guid] = handler;
},
remove: function(elem, type, handler) {
var handlers = elem.events && elem.events[type];
if (!handlers) return
delete handlers[handler.guid]
for(var any in handlers) return
if (elem.removeEventListener)
elem.removeEventListener(type, elem.handle, false);
else if (elem.detachEvent)
elem.detachEvent("on" + type, elem.handle);
delete elem.events[type];
for (var any in elem.events) return
delete elem.handle;
delete elem.events;
}
}
}())
function keymove(event) {
var code = (event.charCode) ? event.charCode : event.keyCode;
switch(code)
{
case 37:
изменение положения элемента
break;
case 38:
изменения положения элемента
break;
}
}
И вызов в другой функции:
Event.add('keypress', keymove);
