This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The PluginArray
interface is used to store a list of Plugin
objects describing the available plugins; it's returned by the window.navigator.plugins
property. The PluginArray
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.
Name | Description | Return Type | Availability |
---|---|---|---|
PluginArray.length | The number of plugins in the array. Read only. | unsigned long | DOM 0 |
PluginArray.item
Plugin
at the specified index into the array.PluginArray.namedItem
Plugin
with the specified name.PluginArray.refresh
The following example function returns the version of the Shockwave Flash plugin.
var pluginsLength = navigator.plugins.length; document.body.innerHTML = pluginsLength + " Plugin(s)<br>" + '<tableid="pluginTable"><thead>' +'<tr><th>Name</th><th>Filename</th><th>description</th><th>version</th></tr>' +'</thead><tbody></tbody></table>'; var table = document.getElementById('pluginTable'); for(var i = 0; i < pluginsLength; i++) { let newRow = table.insertRow(); newRow.insertCell().textContent = navigator.plugins[i].name; newRow.insertCell().textContent = navigator.plugins[i].filename; newRow.insertCell().textContent = navigator.plugins[i].description; newRow.insertCell().textContent = navigator.plugins[i].version?navigator.plugins[i].version:""; }
The following example displays information about the installed plugin(s).
var pluginsLength = navigator.plugins.length; document.write( pluginsLength.toString() + " Plugin(s)<br>" + "Name | Filename | description<br>" ); for(var i = 0; i < pluginsLength; i++) { document.write( navigator.plugins[i].name + " | " + navigator.plugins[i].filename + " | " + navigator.plugins[i].description + " | " + navigator.plugins[i].version + "<br>" ); }
In addition to listing each plugin as a pseudo-array by zero-indexed numeric properties, Firefox provides properties that are the plugin name directly on the PluginArray object.
