Synopsis

navigator.mimeTypes[i]
navigator.mimeTypes["type"]
navigator.mimeTypes.length

Properties

description

A read/only string that provides a human-readable description (in English) of the data type described by the MimeType. This description is more explicit and understandable than the name property.

enabledPlugin

A read-only reference to a Plugin object that represents the installed and enabled plugin that handles the specified MIME type. If the MIME type is not handled by any plugins, the value of this property is null.

The navigator.mimeType[] array tells you whether a given MIME type is supported by the browser. The enabledPlugin property of the MimeType object, however, tells you whether a particular supported type is supported with a plugin (MIME types can also be supported with helper applications, or directly by the browser). If a MIME type is supported by a plugin, data of that type can be embedded in a web page with the <embed> tag.

suffixes

A read-only string that contains a comma-separated list of filename suffixes (not including the "." character) that are commonly used with files of the specified MIME type. For example, the suffixes for the text/html MIME type are "html, htm".

type

A read-only string that specifies the name of the MIME type. This is a unique string such as "text/html" or "image/jpeg" that distinguishes this MIME type from all others. It describes the general type of data and the data format used. The value of the type property can also be used as an index to access the elements of the navigator.mimeTypes[] array.

Description

The MimeType object represents a MIME type (i.e., a data format) supported by Netscape. The format may be supported directly by the browser or through an external helper application or a plugin for embedded data.

Usage

The navigator.mimeTypes[] array may be indexed numerically or with the name of the desired MIME type (which is the value of the type property). To check which MIME types are supported by Netscape, you can loop through each element in the array numerically. Or, if you just want to check whether a specific type is supported, you can write code like the following:

var show_movie = (navigator.mimeTypes["video/mpeg"] != null);
