在不同的浏览器下检测已安装的插件？

Question

I'm wondering if there is a way to detect installed plugins on different browsers. 我想知道是否有办法在不同的浏览器上检测已安装的插件。 So far I have found that you can "detect" plugins on firefox by trying to guess if chrome://path/to/some/plugin/image.gif exists. 到目前为止，我发现你可以通过试图猜测是否存在chrome：//path/to/some/plugin/image.gif来“检测”firefox上的插件。

This code for firefox looks like this: 这个firefox代码看起来像这样：

<img src="chrome://firebug/content/blank.gif" onload="var a=document.getElementById('FireBug'); a.innerHTML = 'You are using FireBug';" style="visibility:hidden">
<div id="FireBug">You are not using FireBug</div>

I'm interested how does the code look in IE (more important to me) and if there are other ways to accomplish this task for other browsers too? 我感兴趣的是代码在IE中看起来如何（对我来说更重要）以及是否还有其他方法可以为其他浏览器完成此任务？

I want to know because I'm having an idiot client who claims he doesn't have installed plugins though I'm 99,99% sure he has. 我想知道，因为我有一个白痴客户声称他没有安装插件，虽然我99,99％肯定他有。 The problem is that some of those plugins are breaking parts of a web site admin control panel I've wrote. 问题是，其中一些插件破坏了我写过的网站管理员控制面板的部分内容。

Anyway I'd be glad to hear any tips,tricks,workarounds and etc for getting the plugin list of the popular browsers (ff,ie,opera,chrome,safari) :) 无论如何，我很高兴听到任何提示，技巧，变通方法等获取流行浏览器的插件列表（ff，即歌剧，铬，野生动物园）:)

This code will list all the plugins installed in the browser 此代码将列出浏览器中安装的所有插件

<html>
<body>
<div id="example"></div>
<script type="text/javascript">
var x=navigator.plugins.length; // store the total no of plugin stored 
var txt="Total plugin installed: "+x+"<br/>";
txt+="Available plugins are->"+"<br/>";
for(var i=0;i<x;i++)
{
  txt+=navigator.plugins[i].name + "<br/>"; 
}

 plugin = navigator.plugins[i];
 document.write("<center><font size=+1><b>");

 document.writeln("<th width=50%>Description</th>");
 document.writeln("<th width=20%>Suffixes</th>");
 document.writeln("<th>Enabled</th>");
 document.writeln("</tr>");
 numTypes = plugin.length;
 for (j = 0; j < numTypes; j++)
 {
  mimetype = plugin[j];

  if (mimetype){
   enabled = "No";
   enabledPlugin = mimetype.enabledPlugin;
   if (enabledPlugin && (enabledPlugin.name == plugin.name))
    enabled = "Yes";
   document.writeln("<tr align=center>");
   document.writeln("<td>");
   document.write(mimetype.type);
   document.writeln("</td>");
   document.writeln("<td>");
   document.write(mimetype.description);
   document.writeln("</td>");
   document.writeln("<td>");
   document.write(mimetype.suffixes);
   document.writeln("</td>");
   document.writeln("<td>");
   document.writeln(enabled);
   document.writeln("</td>");
   document.writeln("</tr>");
  }
 }
 document.write("</table>");
}
</SCRIPT>
</BODY>

You could try this: http://www.sliceratwork.com/detect-installed-browser-plugins-using-javascript 你可以试试这个： http ： //www.sliceratwork.com/detect-installed-browser-plugins-using-javascript

... but this is not going to detect browser add-ons like firebug, noscript, etc. ...但是这不会检测像firebug，noscript等浏览器插件。

That script seems to detect only the following plugins:- 该脚本似乎只检测以下插件： -

Java Java的
3D Markup Language for Web Web的3D标记语言
DjVu 的DjVu
Flash 闪
Google Talk Google Talk
Acrobat Reader 爱看阅读器
QuickTime 的QuickTime
RealPlayer RealPlayer的
SVG Viewer SVG查看器
Shockwave 冲击波
Silverlight Silverlight的
Skype Skype的
VLC VLC
Windows Media Player Windows媒体播放器
Xara Xara
