How do I echo a variable within another variable?

Copy linkTweet thisAlerts:

I have this code:

[CODE]var rand_no = Math.random();
rand_no = rand_no * 100;

var so = new SWFObject(“ep_player.swf?dummyVar=[i want rand_no to be displayed here]”, “ep_player”, “269”, “226”, “9”, “#FFFFFF”);[/CODE]

I want the variable rand_no to be displayed where I specified, how would I do that?

@cgishackFeb 03.2008 — you can create an empty div and add it to that

<i>
</i>var div = document.getElementById("[B]myRandomNumerID[/B]");
div.innerHTML = so;


[code=html]
Random Num: <div id="myRandomNumerID"></div>
[/code]

@dizastixauthorFeb 03.2008 — Hey, I'm not sure how I would do that. Here is my entire script section:

[CODE]
 <script type="text/javascript">
// <![CDATA[

var so = new SWFObject("ep_player.swf?dummyVar=[here, the random number should be echoed", "ep_player", "269", "226", "9", "#FFFFFF");
so.addVariable("skin", "skins/nobius_blue/skin.xml");
so.addVariable("playlist", "play.xml");
so.addVariable("autoplay", "false");
so.addVariable("shuffle", "false");
so.addVariable("repeat", "false");
so.addVariable("buffertime", "1");
so.write("flashcontent");

// ]]>
</script>[/CODE]

so I don't think I can do that with a div...?

@cgishackFeb 03.2008 — well it all depends on how that SWFObject works...

I found this
<i>
</i> so.write("flashcontent"); -- [B]replace &amp;#8220;flashcontent&amp;#8221; with the name of the div ID[/B]

hey, thanks for the help but I ended up just doing it with php since I'm more familiar with that.
