# JavaScript, Firefox and application/xhtml

 * I noticed a problem when serving the blog as application/xhtml.
 * I released the [Transpose Email plugin](http://www.ajaydsouza.com/wordpress/plugins/transpose-email-plugin/)
   which uses a javascript function `Transpose_Email()`.
    Works properly in IE and
   Opera This works perfect in Firefox when the page is served as text/html, but
   the moment I shift to application/xhtml, I get a javascript error saying function
   not found.
 * I have absolutely no idea how to solve this problem so that the function works
   when the page is served as XHTML.
 * Any suggestions?

 * You should keep the JavaScript as an external script and just link to it from
   the XHTML document. You can’t have ‘inline’ JavaScript like that in an XML document(
   as a real XHTML document is). The only option is to escape it properly (read 
   up on CDATA), but keeping scripts and CSS external is the best.

 * Thanks for the post.
    Was able to fix the problem when I got the same feedback
   from [MozillaZine Forum](http://forums.mozillazine.org/viewtopic.php?t=280593).
 * Moved the js to an external file.
 * Released v1.1 of the plugin 🙂
