Tutorials » Actionscripting: Basic: The easiest way in the world to pass information INTO a Flash - Page 3
Problems:
- 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. - How do you copy them from wherever it is you got them from (hidden form
fields, originating URL, etc?)
Thats 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>
