Please pardon the dumb newbie question; I've only been programming Javascript for about 24 hours... :)
I have managed (with some outside help) to embed a shockwave flash object into my page - specifically MultiPowUpload 2.1. It's appearing nicely on the page and seems to be functioning correctly; we can take that part as read.
Now I'm trying to do some more advanced stuff in JavaScript - I have a button, and in the onClick() code I have the following:
var swf = document.getElementById("FlashFilesUpload1");
var itemsCount = swf.filesCount;
alert("items: "+itemsCount);
But the alert statement tells me "items: undefined". It does the same if I set itemsCount to swf.nonExistentProperty - everything is "undefined". But from what I read in the documentation, there definitely is a filesCount property. I tried accessing all the other properties and methods of this swf object, and none of them work, except for toString(), which returns "HTMLObjectElement".
I am obviously addressing this object incorrectly - but what am I doing wrong?
Clarification
In response to @brianpeiris: I am doing this quite differently from the page at the link you suggested. I didn't do this with any great knowledge, I'm just really acting like a monkey, trying to copy other people's code that works, then tweak it so it does what I want... so don't assume I know anything, however obvious - remember, I've only been doing JavaScript for about a day now!
So here's the code for the control itself:
<object id="FlashFilesUpload1" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0"
classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" viewastext>
<!-- Replace symbols " with the " at all parameters values and
symbols "&" with the "%26" at URL values or & at other values!
The same parameters values should be set for EMBED object below. -->
<param name="FlashVars" value="uploadButtonVisible=false&uploadUrl=../ReceiveBulkCases.aspx" />

<embed bgcolor="#F8F6E6" id="EmbedFlashFilesUpload" src="ClientSideControls/ElementITMultiPowUpload2.1.swf"

type="application/x-shockwave-flash" width="450" height="350" flashvars="uploadButtonVisible=false&uploadUrl=../ReceiveBulkCases.aspx">
</embed>
</object>
As you see it's embedded in the HTML as an object, unlike the reference you gave, where they do some other trick using script to get it onto the page.
BTW, when I tried it their way (not very hard, I grant you), I didn't manage to get the control even to appear on my page!
Thanks for your help... much appreciated
