sending data accross windows

Copy linkTweet thisAlerts:
Mar 06.2006

I ran into an interesting problem with a script. What it does is open a window and send a value to a variable in the new opened window

[code]
win=window.open(“something.htm”, “”, “theatermode”);
win.nums=1;
[/code]

now here’s the weird part. the script works perfectly on my computer, but when i put it on the internet it doesn’t work.

@phpnoviceMar 06.2006 — Possibly because of a delay in loading the document into the popup window. Or, perhaps because of cross-domain scripting. Yes? There is no delay and no domain involved when both documents are on your computer.

@PhalonauthorMar 06.2006 — well the part about the window delay i already have covered. i put in a .5 second delay in the window, because it was needed when i used it on my computer. i am curious what you mean by cross-domain scripting and if i need to contact my website provider about it

@phpnoviceMar 06.2006 — Cross-domain issues are only involved if the two documents each come from two different websites. As for the delay... Adding a delay can actually hurt -- not help -- but it depends upon where you added the delay and where, exactly, the error is occurring. You didn't really say what, exactly, "doesn't work."

@PhalonauthorMar 06.2006 — Well I'll try to answer everything in this post:
<i>
</i>win=window.open("picslide.htm", "", "theatermode, height=600, width=700");
win.nums=1;

I use this to open the window and send the variable.

then on the picslide.htm i use
<i>
</i>&lt;body bgcolor="black" onLoad="Javascript:setTimeout('start()', 500);"&gt;

to delay calling the function because otherwise the varabile comes up as "undefined" when i tested on my computer. i also used various delay times to see if i didn't have it wait long enough to check the variable's value. but no luck. This is all at the same website and this isn't the first page to do this. Also i did try it with no delay and it still comes back with the same, nums is "undefined". For the full page, its at www.marshallareastagecompany.org/home.htm

This is just a test site before it gets it's own domain, and yes i'm the webmaster of the site space im testing this at (just in case that might be an issue).

*note- to open the page, scroll down, and click on one of the numbers on the picture of the golf course.

@phpnoviceMar 06.2006 — I see. Well, the delay is actually needed between these two statements:
<i>
</i>win=window.open("picslide.htm", "", "theatermode, height=600, width=700");
win.nums=1;

This is because, while the window is opening, it is unavailable to script references. So, try this and increase yoru other delay, too:
<i>
</i>win=window.open("picslide.htm", "", "theatermode, height=600, width=700");
window.setTimeout("win.nums=1", 500);

Success!
