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" ) 方法。

注意 : Own properties of PluginArray objects are no longer enumerable in the latest browser versions.

方法

PluginArray.item: 返回 Plugin at the specified index into the array.
PluginArray.namedItem: 返回 Plugin with the specified name.
PluginArray.refresh

范例

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>"
  );
}

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.
