本文介绍如何使用Flex通过ExternalInterface调用JavaScript来直接获取浏览器信息，包括appName、userAgent和appVersion等，并提供了一个可运行的例子。
Hi Amit,
The replies from Gnomann are correct.
Following the logic that Gnomann cited in his second post (suggesting using ExternalInterface to execute browser JavaScript), following are some examples.
These examples also demonstrate how JavaScript methods can be written in-line directly in the ExternalInterface.call() execution:
var appName:String = ExternalInterface.call( "function getAppName(){ return navigator.appName; }" ) ;
var userAgent:String = ExternalInterface.call( "function getUserAgent() { return navigator.userAgent; }" ) ;
var appVersion:String = ExternalInterface.call( "function getAppVersion(){ return navigator.appVersion; }" ) ;
I have posted a different, runnable example here:

You can right-click on the swf at the link above for " View Source "
btw ... an advantage of writing the JavaScript methods in-line in the ActionScript ExternalInterface.call() executions is that all of the code can be encapsulated in the Flex logic. That is you do not have to write the JavaScript separately in the HTML wrapper. You can if you want, of course. Certainly no harm in that ;-) Since your original question was how to detect the browser information "directly from FLEX", I suspect you might like being able to write the JavaScript methods in-line ;-)
Please post back regarding whether the above answers your question, and if you find it helpful :-)
Best regards,
