[Javascript] replace

[javascript@xxxxxxxxxx (matthew garland)]

Hi,

Learning a little Javacript beyond "window.open". Hope you can help. =

This is the set up: I have two frames on a page: "home" with a home.html =
page, and "dummy" with a blank dummy.html page. The home frame has a Flash =
movie embedded in it. The dummy frame is an invisible one-pixel frame. =

When I want to communicate between Flash and the window, only one action =
is supported in all 4.0+ browsers--the link or Flash "getURL()" command. =
So the workaround is this: the Flash calls a page into the "dummy" frame (=
getURL ("aPopUP.html","dummy"//to target the frame), which in turn =
executes Javascript within the onload handler. =

This works like a charm, and I use it to call pop ups from the Flash movie.=


But here's the problem: when the user tries to leave the site, and hits =
the back button, all the pop ups come up again, because the back button is =
retreading the history of the window. Each dummy page is called up again, =
and "onload"--the pop up comes up. YRRECH! Annoying, especially since my =
site is a FLash site that loads a lot of long text in pop ups. =

I only know enough Javascript to open pop ups, but my reseach has led me =
to at least one solution: if every time the dummy pages loaded, they fired =
off the pop ups, then waited a second and then used the replace command to =
return the location of the dummy frame back to the original "dummy.html," =
there would be no history and the back button would take you right out of =
the site, with no retread of the pop ups. =

but I can't get the code to work: =

{//in the header of each dummy page

function popUp () =

window.open (page,window,features)

}

function eraseHistory() {

setTimeout ('location.replace('dummy.html')',1000)

}

//in the onload handler of the dummy page

onload=3D"popUp();eraseHistory()"

Not only does this not work, it makes the pop Up not work! Is there =
something wrong with my code? I know nothing.Help!

Thanks in advance

Matt
