How do I detect a custom plugin in Firefox/IE/Chrome?

Question

My team wants to build a "plugin" for firefox/chrome/IE. How do I use javascript to detect if this plugin (not extension) is installed?

I would like to have a piece of javascript that can detect if a certain plugin is installed. Returns true if installed, returns false otherwise.

For example...how do I get a list of plugins, and then loop through to see if one of them match my plugin name? If match, return 1.

Answer 1

navigator.plugins will have an array of plugins that you can check.

This exists for Firefox, Chrome, and IE (at least version 8, I don't have a lower version to test)

Here's what the array looks like in webkit:

Answer 2

You can get browser plugins by this javascript code:

<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>
<br/>
<script>
