Navigator.registerContentHandler()

 

Summary

Allows web sites to register themselves as possible handlers for content of a particular MIME type.

Note: Web sites may only register content handlers for themselves. For security reasons, it's not possible for an extension or web site to register content handlers targeting other sites.

Syntax

JavaScript
navigator.registerContentHandler(mimeType, uri, title);
  • mimeType is the desired MIME type as a string.
  • uri is the URI to the handler as a string.
  • title is the title of the handler presented to the user as a string.

Example

js;auto-links:false
navigator.registerContentHandler(
    "application/vnd.mozilla.maybe.feed",
    "http://www.example.tld/?foo=%s",
    "My Feed Reader"
);

Notes

For Firefox 2 and above, only the application/vnd.mozilla.maybe.feed, application/atom+xml, and application/rss+xml MIME types are supported. All values have the same effect, and the registered handler will receive feeds in all Atom and RSS versions (see bug 391286).
