在不同的浏览器下检测已安装的插件？ [英] Detecting installed plugins under different browsers?
问题描述
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。
到目前为止，我发现你可以通过猜测是否存在chrome：//path/to/some/plugin/image.gif来检测firefox上的插件。
I'm wondering if there is a way to detect installed plugins on different browsers. 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.
这个firefox的代码如下所示：
This code for firefox looks like this:
<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>
我很感兴趣代码在IE中看起来如何（对我来说更重要）如果有的话还有其他方法可以为其他浏览器完成这项任务吗？
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。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。
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. The problem is that some of those plugins are breaking parts of a web site admin control panel I've wrote.
无论如何，我很高兴听到任何有关获取流行浏览器插件列表的提示，技巧，变通方法等（ff，即歌剧，Chrome，safari） ）:)
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) :)
推荐答案
此代码将列出浏览器中安装的所有插件
This code will list all the plugins installed in the browser
<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/>";
}
document.getElementById("example").innerHTML=txt;
</script>
</body>
</html>
