NetvClientDetect 


REVISION HISTORY

---
Version 2.2  //remind to update 'detector_version' in function!
---
- bugfix ie if no flash installed "playerVersion undefined"

---
Version 2.1  //remind to update 'detector_version' in function!
---
- added detector_version

---
Version 2.0  //remind to update 'detector_version' in function!
---
ajax support:
- xx=function() for all functions, 
- new getFlashVersion for ie (modified from google swfobject)
- removed closing object slash object open tag in function showflash()

usage 
<div id="swf-container" style=""><!-- swf gets here by innerHTML --></div>
<script type="text/javascript">
 	var F=new NetvClientDetect();
	swfembed = F.showflash({
	 	[...]
		mode:'return' // write, return
	)}
	$('swf-container').innerHTML = swfembed;
</script>
