document.plugins[i] document.plugins.length document.embedded-object-name
The plugins property of the Document object is a synonym for the embeds property. Both properties refer to an array of JavaObjects that represent embedded data being displayed by a plug-in.
The embeds property is the preferred way to access this array, since it avoids confusion with the Navigator.plugins array, which is totally different than the array Document.plugins. See Document.embeds for full details.
