Core Web Programming, Second Edition

25.19. The MimeType Object

The MimeType object describes a MIME type. The navigator.mimeTypes array lists all types supported by the browser, either directly by plug-ins or through external “helper” applications. For example, you could use code like the following to insert a link to an Adobe Acrobat file only if the current browser supports Acrobat; otherwise, you would use a plain text document.

document.writeln('For more information, see');
if (navigator.mimeTypes["application/pdf"] != null) {
  document.writeln
    ('<A HREF="manual.pdf">the widget manual</A>.');
} else {
  document.writeln
    ('<A HREF="manual.text">the widget manual</A>.');
}

For a list of common MIME types, see Table 19.1.
