call variable in ,js to swf file

I need to pass a variable number from the random number generator in the <HEAD>

to the "var so = new SWFObject" statement in the body.

Note that '+gifnum+'.swf does not call any of my swf files, such as 1.swf, 2.swf, etc.

But that's what I want to have happen.

However, the "document.write" is calling my gif files (1.gif, 2.gif, etc.) just fine.



<SCRIPT LANGUAGE="JavaScript">
function setRandomNumber(){
gifnum = Math.floor(Math.random() * 6) + 1;}
setRandomNumber()
</SCRIPT>
</head>


<body>
<div id="flashcontent"></div>
<script type="text/javascript">
var so = new SWFObject("images/'+gifnum+'.swf", "sotester", "910", "250", "9", "#FF6600");
so.write("flashcontent");
</script><br>
      
      
<script language="JavaScript">
document.write('<img width="200" height="191" src="http://videojobshop.com/images/' + gifnum + '.gif"><br>');
</script>

I prefer
<SCRIPT LANGUAGE="JavaScript">
function setRandomNumber(){
  return Math.floor(Math.random() * 6) + 1; 
}
</SCRIPT>
</head>
  
<body>
<div id="flashcontent"></div>
<script type="text/javascript">
var so = new SWFObject("images/'+gifnum+'.swf", "sotester", "910", "250", "9", "#FF6600");
so.write("flashcontent");
</script><br>
      
      
<script language="JavaScript">
document.write('<img width="200" height="191" src="http://videojobshop.com/images/' + setRandomNumber() + '.gif"><br>');
</script>

Your problem is you have not properly used the string quotes

Replace the esixting statement with the following one and you would have it (Copy Paste from here):

var so = new SWFObject('images/'+gifnum+'.swf', "sotester", "910", "250", "9", "#FF6600");

Thanks.

Ahh, Missed that...

I see that my suggestion then would not work well if you want to match the random swf with the image

I got this from Sinoj Sebastian, which solved my problem


var so = new SWFObject("images/"+gifnum+".swf", "sotester", "910", "250", "9", "#FF6600");

For a string you can use "single quote" or "double quote". But you cannot mix it together. If you have a "single quote" inside "double quote",  "single quote" will be considered as the part of the string.
