PluginArray

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.

Properties

Name Description Return Type Availability
PluginArray.length The number of plugins in the array. Read only. unsigned long DOM 0

Methods

PluginArray.item
Returns the Plugin at the specified index into the array.
PluginArray.namedItem
Returns the Plugin with the specified name.
PluginArray.refresh
Refreshes all plugins on the current page, optionally reloading documents.

Examples

The following example function returns the version of the Shockwave Flash plugin.

var pluginsLength = navigator.plugins.length;

document.body.innerHTML = pluginsLength + " Plugin(s)<br>"
  + '<table id="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>"
  );
}

Browser compatibility

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.
