Change single number in embed attribute every time page visited

[elbin]

Hello,
first to say that I am a total beginner in Javascript but I know some programming (python in particular) and am able to understand methods/parameters and so on.

Here's my problem:
I am trying to set up a page that changes every time it's visited, but without using php(which i don't know either) because it's not active on the server. The thing that should change is a single number in one attribute of an <embed> tag inside an <object>. The attribute itself is a long string of attributes - settings for the flash that runs in this embed-tag. In general I would like to change the number according to a file storing the number of visits and increments it with each new visit. So I need to set the whole attribute (which is a string called 'list' in the code below) from outside - with a javascript.

What I am trying now is simply setting the attribute without any changing/files. It looks like this:

[HTML]<script type="text/javascript">
function lista()
{
var list = "url=search_fil es/foret.swf&amp;f euilles=2&amp;o bjectif=1000000 00&amp;texte=Ke ep the left mouse button pressed &lt;br&gt; and move to look around.&amp;zoo mM=Zoom %2D&amp;zoomP=Z oom %2B";
document.embeds[0].setAttribute(" flashvars", list);
}
</script>[/HTML]

and the whole <object> looks like this:

[HTML]<object id="Flash" codebase="http://download.macrom edia.com/pub/shockwave/cabs/flash/swflash.cab#ver sion=6,0,40,0" classid="clsid: D27CDB6E-AE6D-11cf-96B8-444553540000" height="377" width="481">
<embed src="search_fil es/loader.swf" quality="high" bgcolor="#B3F28 5" name="&lt;NAME& gt;" type="applicati on/x-shockwave-flash" pluginspage="ht tp://www.macromedia. com/go/getflashplayer" height="377" width="481"></object>[/HTML]

I execute the function onload but the flash doesn't seem to get the parameters and stops after it's initial animation contained in the loader.

Where am I making a mistake?

To change the number each time without using server-side code, you need to use cookies.

Changed the thread title to better describe the problem.

Thank you for changing the title, I'll write more specific next time. Now i understand the cookies, but I still don't know why the code I gave you doesn't work. It doesn't set the embed attribute. I suppose I should put it into the checkCookie function that executes onload, but why doesn't it work?

[acoder]

It probably doesn't work because the string being passed needs to be URL-encoded. Have you got it working with cookies?

[elbin]

I tried it but it doesn't work. I put the setattribute statement in the case when the cookie does not exist.

When I said I understood cookies I didn't mean I was able to use them, I just understand what they do generally. What do you mean URL-encoded?
