NavigatorPlugins.plugins
Returns a PluginArray
object, listing the plugins installed in the application.
In Firefox 29 and later, enumeration of the navigator.plugins
array may be restricted as a privacy measure. Applications that must check for the presence of a browser plugin should query navigator.plugins
or navigator.mimeTypes
by exact name instead of enumerating the navigator.plugins
array and comparing every plugin's name. This privacy change does not disable any plugins; it just hides some plugin names from enumeration.
Syntax
var <var>plugins</var> = navigator.plugins;
plugins
is used to access Plugin
objects either by name or as an array of items.
The returned value is not a JavaScript array, but has the length
property and supports accessing individual items using bracket notation (plugins[2]
), as well as via item(index)
and namedItem("name")
methods.
Examples
The following example function return for the Flash version.
function getFlashVersion() { var flash = navigator.plugins['Shockwave Flash']; if (flash === undefined) { // flash is not present return undefined; } return flash.version; }
The following example prints out information about the installed plugin(s) for the high-level document.
var L = navigator.plugins.length; document.write( L.toString() + " Plugin(s)<br>" + "Name | Filename | description<br>" ); for(var i = 0; i < L; i++) { document.write( navigator.plugins[i].name + " | " + navigator.plugins[i].filename + " | " + navigator.plugins[i].description + " | " + navigator.plugins[i].version + "<br>" ); }
Notes
The Plugin
object exposes a small interface for getting information about the various plugins installed in your browser. A list of plugins is also available by entering about:plugins
in the browser's Location bar.
