HTML页面内的Chrome应用处理MIME类型

Question

Is it possible to create a chrome app to render an embed tag with a specific MIME type inside a HTML page (like what Flash player does for .swf)? If yes, when does Chrome browser unload the app?

Thanks

Yes, it's possible as documented in the distributing page. Also see this other SO question .

For posterity:

Registering Native Client modules to handle MIME types If you want Chrome to use a Native Client module to display a particular type of content, you can associate the MIME type of that content with the Native Client module. Use the nacl_modules attribute in the Chrome Web Store manifest file to register a Native Client module as the handler for one or more specific MIME types. For example, the bold code in the snippet below registers a Native Client module as the content handler for the OpenOffice spreadsheet MIME type:

{
   "name": "My Native Client Spreadsheet Viewer",
   "version": "0.1",
   "description": "Open spreadsheets right in your browser.",
   "nacl_modules": [{
      "path": "SpreadsheetViewer.nmf",
      "mime_type": "application/vnd.oasis.opendocument.spreadsheet"
   }]
}

The value of “path” is the location of a Native Client manifest file (.nmf) within the application directory. For more information on Native Client manifest files, see Manifest Files .

The value of “mime_type” is a specific MIME type that you want the Native Client module to handle. Each MIME type can be associated with only one .nmf file, but a single .nmf file might handle multiple MIME types. The following example shows an extension with two .nmf files that handle three MIME types.

{
   "name": "My Native Client Spreadsheet and Document Viewer",
   "version": "0.1",
   "description": "Open spreadsheets and documents right in your browser.",
   "nacl_modules": [{
     "path": "SpreadsheetViewer.nmf",
     "mime_type": "application/vnd.oasis.opendocument.spreadsheet"
   },
   {
      "path": "SpreadsheetViewer.nmf",
      "mime_type": "application/vnd.oasis.opendocument.spreadsheet-template"
   },
   {
      "path": "DocumentViewer.nmf",
      "mime_type": "application/vnd.oasis.opendocument.text"
   }]
}

The nacl_modules attribute is optional—specify this attribute only if you want Chrome to use a Native Client module to display a particular type of content.
