FLASH: Re: Detecting if java enabled for CFSET flashmoviename.swf

[Jack Monteleagre]

Patricia,


Thanks for the quick response however my problem is not that I'm trying

to determine if a browser supports Java or even what type of browser is

being used. That is easy enough through cgi variables. 


Symptoms:

The problem I'm having can best be explained with the following link and

a couple of steps:

1. View http://www.trifolium.com/ with Netscape

2. Everything including the Flash file at the top should be working fine

3. In Netscape go to Preferences, Advanced, Uncheck "Enable JAVA"

4. View page, Now it should continuously show the loading screen.


Cause:

Much like this site I am using in the body tag and onload function that

= play (). The play () function is defined in the Javascript. This code

looks like this:



function go() 


	{

    var InternetExplorer = navigator.appName.indexOf("Microsoft") != -1

    var header = InternetExplorer ? window.movie : window.document.movie

                  header.Play()

	}


In the first frame of the flash file I have set a stop () command so

that soon as the user hits the page it holds the playing of the movie

until everything is loaded which then triggers off the onload function

in the body tag which in turn executes the go () function in javascript

which sends a play () command to Flash.


Again the problem's core issue is that JAVA needs to be enabled for

these steps to work. Else it will not since the message is never sent to

Flash or Received by Flash, take your pick I'm not sure.


Possible Solution:

The possible solution to this problem is since Cold Fusion code will

always execute before Javascript will there must be a way of using Cold

Fusion to detect if the End Users browser has the setting "Enable JAVA"

turned on. If that is possible then I could easily point the End User to

a Flash file that has the "stop ()" function in the first frame or a

Flash file that just begins playing after a few frames have past etc.


I know you guys at Figleaf are pretty good at merging Flash and CF

figured I'd shoot this on the chattyfig mailing list since this is an

issue I'm sure someone has run into before.


Thanks,


Jack

--------- Original Message ---------------



All,


I'm trying to come up with an equivalent solution to detecting if java

is enabled on a end user's browser and if so then use a specific flash

file in the object/embed tags that are set through use of ColdFusion. So

far I have this javascript:


if (navigator.appName == 'Microsoft Internet Explorer' &&

navigator.appVersionindexOf('MSIE 3'))

    var java = false;

else

    var java = navigator.javaEnabled();



My question is if I am using cold fusion variables to define the

parameters and settings how can i add logic to this to be able to use

say a specific flash file instead of another? (this is a specific

problem i've seen when trying to do fscommands to flash or flash to

javascript, etc.) I want to create a work around that enables me to use

one of two flash files, etc.


The problem I see is that since cold fusion will always execute before

javascript this is not possible. Has anyone tried this and if so how?


Thanks,


Jack
