Returns a PluginArray object, listing the Plugin objects describing 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 plugins = navigator.plugins;
plugins is PluginArray object used to access Plugin objects either by name or as a list 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 returns the version of the Shockwave Flash plugin.
function getFlashVersion() {
var flash = navigator.plugins.namedItem('Shockwave Flash');
if (typeof flash != 'object') {
// flash is not present
return undefined;
}
if(flash.version){
return flash.version;
} else {
//No version property (e.g. in Chrome)
return flash.description.replace(/Shockwave Flash /,"");
}
}
The following example displays information about the installed plugin(s).
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:"";
}
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.
Specification
This isn't defined in any specification.
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.
