Hi,
sounds like a problem with cleaning up events at page unload.
this has been discussed as a problem only apparent in the combination
of internet explorer and svg viewer and can be avoided by using
something like:
function init(evt) {
if ( window.parent != null ) parent.onbeforeunload = exit;
}
function exit(evt) {
for (i=0; i<registeredEvents.length; i++) {
registeredEvents[i].removeListener();
}
}
of course, to do so, you have to write some code to gather all
registered events in the array that gets iterated through in the "exit"
function. personally, i use something like:
var registeredEvents = new Array();
function RegisteredEvent(argTarget,argType,argHandler) {
this.target = argTarget;
this.type = argType;
this.handler = argHandler;
this.addListener();
}
RegisteredEvent.prototype.addListener = function() {
this.target.addEventListener(this.type,this.handler,false);
};
RegisteredEvent.prototype.removeListener = function() {
this.target.removeEventListener(this.type,this.handler,false);
};
function registerEvent(argTarget,argType,argHandler) {
registeredEvents[registeredEvents.length] = new RegisteredEvent
(argTarget,argType,argHandler);
}
function unregisterEvent(argTarget,argType,argHandler) {
temp = new Array();
for (i=0; i<registeredEvents.length; i++) {
if (registeredEvents[i].target != argTarget ||
registeredEvents[i].type != argType || registeredEvents[i].handler !=
argHandler) {
temp[temp.length] = registeredEvents[i];
}
else {
registeredEvents[i].removeListener();
}
}
registeredEvents = temp;
}
finally, replace all occurences of "object.addEventListener
(type,handler,false);" with "registerEvent(object,type,handler)" and
your events will be cleaned up before your page unloads.
cheers,
hannes
