meaning that MIME types

if (navigator.mimeTypes) {

document.writeln(“<h3>Loaded Plugins:</h3>”);

document.writeln(“<ul>”);

for (var i=0; i < navigator.plugins.length; i++) {

document.writeln(“<li>” + navigator.plugins[i].name + “ (“

+ navigator.plugins[i].description + “)</li>”);

}

document.writeln(“</ul>”);

}

</script>

</body>

</html>

This page prints out a list of all registered plugins and their descriptions. But the plugin object holds a

secret; it is actually a collection of MIME types, meaning that MIME types for the plugin can be accessed

like this:

var oMimeType = navigator.plugins[0][0];

This line of code accesses the first MIME type supported by the first plugin. So now, you can update the

previous example to include the registered MIME types for each plugin:

<html>

<head>

<title>Plugins Example</title>

</head>

<body>

if (navigator.mimeTypes) {

document.writeln(“<h3>Loaded Plugins:</h3>”);

document.writeln(“<ul>”);

for (var i=0; i < navigator.plugins.length; i++) {

document.writeln(“<li>” + navigator.plugins[i].name + “ (“

+ navigator.plugins[i].description + “)</li>”);

document.writeln(“<ul>”);

for (var j=0; j < navigator.plugins[i].length; j++) {

document.writeln(“<li>” + navigator.plugins[i][j].type +

“</li>”);

}

document.writeln(“</ul>”);

}

document.writeln(“</ul>”);

}

</script>

</body>

</html>

Now this example displays each plugin’s name and description, followed by a list of supported MIME

types.
