Hi Pamela,
I was not sending the origin/target, I think that was the problem =)
but now I've another problem with postmessage... =/
I'm trying to do the same thing yet, to send wave viewer to the local page
using postmessage... in the local page I try to assign the value to a global
variable in the eventlistener
but it's not working... simply it seems to be a local variable there.
here's a part of the code:
//Here I declare the variable
viewer = null;
//Here I try to assign them, and here it seems to work fine
window.addEventListener("message", onmessage, false);
function onmessage(e)
{
if (e.data != null && e.data != "undefined" )
{
viewer = e.data;
origin = e.origin;
}
}
//But here there's no value at all in viewer
function NewItem(wave_id)
{
alert(viewer);
}
