Hello,

I hope you guys can help me since i did a lot of googling and couldnt find anything .

I am trying to make a music player open in a new window, i got this part right ... but now i want that when you navigate in the parent window to a new location ... and click add to a music file to append a javascript code in the pop-up HTML to add the new song ... withought reloading the pop-up since that would stop the player ...

I managed to do a code to detect the pop-up ... but if the opener is in the same location ... as soon as i navigate to another location in the opener ... it fails to detect the pop-up.

Thanks a lot.

I'd rather take another way....
Make your popup standalone, and let him poll a db, or a PHP/ASP page via ajax calls to verify his playlist content.

That way:
1) the user click a link to add a song => a php/asp script save it in the session.
No messing through several windows.
2) In the mean time, have a polling interface made, that will record that an additional song has been added, and while it's not have been asked by the player, stay in a "to be read" status.
3) Make the player window ask the interface every 2 or 3 seconds for updates (the "to be read" messages) Make the polling interface add a meaningful message (via json, for example) that the return ajax function will be able to parse, and let that function do the update of the playlist from the player window directly.

That way, you will avoid every pitfall you might have with window handler visibility.
It may looks like a lot, but it's not that hard.

thanks for your advice
