Hi, I'm really noob in this postmessage cross-iframe stuff,
I tryed to do the following in XML:
http://hosting.gmodules.com/ig/gadgets/file/117372586241155512680/openscape_tasks.xml
and in my localhost javascript I tryed this:
var viewer = new String();
function TextChanged( wave_item, new_text )
{
if (new_text == '')
window.location = 'clear/'+wave_item;
else
window.location = 'update/'+wave_item+'/'+escape(new_text);
//wave.getState().submitDelta({'timestamp':currentTime,'author_id':viewer});
}
function NewItem(wave_id)
{
alert('NewItem');
window.location = 'http://cur3w12c.global-ad.net/new/'+wave_id+'/'+viewer;
}
function onmessage(e) {
alert('LOCAL - Receiving data');
viewer = e.data;
}
window.onload = function()
{
alert('LOCAL - AddListeners');
window.addEventListener('message', onmessage, false);
var win = parent.postMessage ? parent : (parent.document.postMessage
? parent.document : undefined);
alert('LOCAL - Posting Ready of WIN: '+win);
win.postMessage( 'ready' );
/*if (typeof window.addEventListener != 'undefined') {
window.addEventListener('message', onmessage, false);
} else if (typeof window.attachEvent != 'undefined') {
window.attachEvent('onmessage', onmessage);
}*/
}
but I'm getting the error:
Unsafe JavaScript attempt to access frame with URL

frame with URL
http://cur3w12c.global-ad.net/kjuFEQZwA/. Domains, protocols and ports must
match.
I can't realize what's the right way to do that.
