检测客户端浏览器是否禁用/允许java applet？ [英] Detecting if the client browser disabled/allows java applets ?
问题描述
在我的一个网页上有一个java小程序在我的电脑上工作正常。
但是我注意到在其他一些计算机上禁用了java小程序的运行。
我收到错误消息Classnotfound
如果允许java applet，有没有办法检测（使用cgi resp.javascript）？
我想要如果不允许applet，则显示简单的图片而不是applet窗格。

On one of my web pages there is an java applets which works fine on my computer.
However I noticed on some other computer that the run of java applets are disabled.
I got an error message "Classnotfound"
Is there a way to detect (with cgi resp. javascript) if java applets are allowed?
I would like to show a simple picture instead of the applet pane if applets are not allowed.

没有这样的事情。我会做一些猜测。
这些机器是..
a）运行Win
b）使用IE作为浏览器
c）浏览器抛出''ClassNotFoundException'的

您可以使用JAvascript检测Java是否已启用，
但这不是问题所在。

There is no such thing. I will make some guesses.
These machines are..
a) Running Win
b) Using IE as a browser
c) the browsers are throwing ''ClassNotFoundException''s

<http://www.physci.org/codes/javafaq.jsp#appletie>
d) this reports ''1.1.4''

You can detect if Java is enabled using JAvascript,
but that is not the problem here.

是的，对于您认为的问题，以及

Yes, to both the problem you thought you had, as well as the
problem I suspect you actually have. You need to fix both to
get the untlimate effect you want. Both can be done without
Javascript.
