Inline JavaScript

Hank Ratzesberger
I want to include inline JavaScript in an
xhtml file the currently uses epilogue.

However, the content within <script> is not xhtml
and putting the script in comments (as below) means
it will get excluded by epilogue.

Not sure what I need to do.


<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:xforms="http://www.w3.org/2002/xforms"
      xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
      xsl:version="2.0">

 <head>
 </head>
 <body>

   <script language="JavaScript" type="text/javascript">
    <!--
  var streams = new Array();
  ...
  showStreams();
    -->
 </script>

</body>
</html>

Regards,
Hank

Hi Hank,

I think that a long time ago, some browsers did not recognize the <script>
tag, so those browsers were displaying the content <script>, which was
obviously not the desired effect. To avoid this, people were putting the
JavaScript in an HTML comment. I don't think that anyone in his right mind
would use a browser so old that it wouldn't know about the <script> tag,
so I would suggest you just remove the comment ;).

Re: Inline JavaScript

Hank Ratzesberger
Alex,

Sorry to be unclear, but commenting around the
JavaScript was an attempt to eliminate an xml
processing exception:

  class org.orbeon.oxf.common.ValidationException
  MessageFatal Error: Element type "streams.length" must be followed by either attribute specifications, ">" or "/>".
  Locationoxf:/localvideo/index.xhtml
  Line116

In an xhtml file that begins like this:

  <?xml version="1.0" encoding="UTF-8"?>
  <html xmlns="http://www.w3.org/1999/xhtml"
        xmlns:xforms="http://www.w3.org/2002/xforms"
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
        xsl:version="2.0">

I attempted to place some JavaScript code.  I am
sure any code would have the same effect:

 <script language="JavaScript" type="text/javascript">

  var streams = new Array();
  var validFPS = new Array(0,1,2,3,4,5,6,7,8,9,10,15,20,25);
  var size = new Array();

So, the question is how/whether I can include inline javascript
in a document meant to be processed mostly by epilogue. i.e.

<page id="LocalVideo" path-info="/localvideo/"
   model="oxf:/content.xml"
   view="oxf:/localvideo/index.xhtml" />

Thank you,
Hank

If you code is valid XML text, it will work, like the fragment below:

The problem is of course that you have in your Javascript code a "<"
character at line 116, which is in XML a character indicating the
beginning of an element, hence the error.

You have two ways of fixing this:

o using an entity instead, i.e. &lt;

o surrounding your Javascript code with a CDATA section, as follows:

   <script language="JavaScript" type="text/javascript">
     <![CDATA[
       var streams = new Array();
       ... etc. ...
     ]]>
   </script>

Erik,

Thank you, I missed the obvious (and did
actually use CDATA a minute after I
wrote my last letter. )

One of my issues has been to provide something
accessible to staff only familiar with html.
I think we have decided that we will split
things and let them create static html pages
created under a Dreamweaver template.

(I went as far as converting html with subversive  
<div class="xsl:value-of" href="/root/somedata">
to xsl, but it's too much trouble for xforms
files.  In the long run, I hope I can put
together a real CMS.)
