passing variables via javascript to flash

I'm making a flash piece that let's the user select song titles and then pops open a window that contains info about the song as well as plays the song. I've made a menu in flash that via javascript opens up a specially sized window with one flash piece. The idea is to pass the flash piece a variable (the selection from the menu) so that it knows what xml doc and mp3 to load in. So, to open the window, I have used this code: getURL ("javascript:void(window.open('mp3.html','MyWindow Name','resizable=no,height=400,width=550,top=0,lef t=0,right=0,bottom=0'))");
I've also written this code: variable = this.text; which lets me know which song was selected. So, how do I pass this variable to the html page so that the flash piece embedded in that page sees the variable and acts accordingly? Thanks in advance.

first check here on affect Flash with Javascript:
http://www.flashkit.com/tutorials/In...77/index.shtml

now what you may want to do is create a javascript function in the html file like:

function OpenChild(someStr){
childWindow = window.open('mp3.html','MyWindowName','resizable=n o,height=400,width=550,top=0,left=0,right=0,bottom =0'))");
// here you want do do some code to check to see if the window has already been loaded(i dont remember this code off the top of my head

// then if your flash movie is formatted like it says to in the above tutorial, you can do the following

window.document.childWindow.FlashMovie.SetVariable ("someStr", flashStr);
//where FlashMovie is the OBJECT ID set in the html file of the child window

}

so instead in your flash file you can simply make a call to getURL("JavaScript:OpenChild("+str+");"

actually its more of a matter of having that flash movie loaded in time, than having the childWindow load in time before you do the SetVariable.

to ensure that, i _think_ you can do this.

in the parent window, you can create a global variable and another function:

var loaded = null;

function ChildMovieIsLoaded(){
loaded = true;
}

so within your child flash movie you can have a call to getURL("JavaScript:ChildMovieIsLoaded()", _parent); when the movie has been loaded of course...

and then in your OpenChild function after you do a window.open(), you can do:
for(i=0; i < 1000000 || loaded != null; i++){}
if(loaded == null){
alert("Child Movie not fully loaded in time");
}

and do an evil little polling loop(which shouldnt be too bad if your movie doesnt take too long to load.

Thanks for your help. I'm swamped right now, so I haven't actually gotten to try what you suggested. But, I do appreciate your help. Thanks.
