Problems:

  1. How do you pass [parameters] to URL.swf without causing syntax problems?
    You create a URL encoded (escaped) parameterized query, such as: “URL.swf?param1=value¶m2=value”
    Just make sure you add that first question mark, the rest is ignored bu the EMBED command.
  2. How do you copy them from wherever it is you got them from (hidden form fields, originating URL, etc?)
    That’s a good question. Unfortunately you must rely on simple Javascripting to dynamically generate the “EMBED” code as in Figure 1. This means that the code displayed in Fig 1 is pushed to the browser at run time (page-display time) using the document.writeln (); function.

If you chose to pass information via the URL line, here is the code to intercept that parameter:

href=document.location.href; 
param=href.substr(href.indexOf('?')); 

Fig. 2 – Sample code to intercept parameters from within the containing document

so if your containing document is URL.htm and you launch it with the following URL:

http://www.domain.com/URL.htm?param=Help_is_on_the_way

Then the value of "param" in Fig 2 will be "?param=Help_is_on_the_way"

No lets see the Fig 2 code, along with the code that will dynamically plug in the parameter into the <OBJECT> block:

<html>
<head>
</head>

<body>

<script language="javascript">
href=document.location.href;
params=href.substr(href.indexOf('?'));
document.writeln ('<OBJECT classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"');
document.writeln (' codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=5,0,0,0" WIDTH=550 HEIGHT=400>');
document.writeln (' <PARAM NAME=movie VALUE="URL.swf' + params + '"> <PARAM NAME=quality VALUE=high> <PARAM NAME=bgcolor VALUE=#FFFFFF> ');
document.writeln (' <EMBED src="URL.swf" quality=high bgcolor=#FFFFFF WIDTH=550 HEIGHT=400 TYPE="application/x-shockwave-flash" PLUGINSPAGE="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash"></EMBED></OBJECT>');
</script>
</body>

</html>

» Description: Hmm... what to say about this one? It's reminiscent of the closing notes of the opening music from the Three Stooges done in a church organ style with a closing cymbal crash. I'll give this one away gratis, but feel free to check out my free loops and potential upcoming license-mandated ones over in the respective part of Flashkit.
