This is not going to affect old browsers, but it *might affect new ones... the
key point is this:
"No one is using browsers so old as to require this coding for its original
purpose but many will soon be using web browsers where this coding causes the
scripts to be commented out completely." I don't know if that will be the case
but at the moment it seems to be more of a validation problem.
But the article has a valid point, it has become force of habit for me too
after 10 years of coding JavaScript comments before my scripts in this way, you
don't think about it after a while you just do it, in truth I have not found a
solution to accommodate XHTML comments and ordinary comments (as used in
Tapestry) but this appears to be an elegant solution (actually so simple and
obvious that it leaves me kicking myself), and it works perfectly in Tapestry
templates so I think I may change all my comments to use:
<script type="text/javascript">
/* <![CDATA[ */
// content of your Javascript goes here
/* ]]> */
</script>
And maybe its something the tapestry devs could investigate?
Thanks for the tip,
Peter

Subject: RenderSupport addScript old browsers
Hi,
how "safe" is using addScript method of the RenderSupport considering
old browsers support? Tapestry renders something like:
<script type="text/javascript">
<!--
Tapestry.DEBUG_ENABLED = true;
Tapestry.onDOMLoaded(function() {
urchinTracker();
var pp_gemius_identifier = new
String('dw.rQgdz5MHhw1_2bpPIltTI.IjBDjCvnQC0f_bLGdj.v7');
});
// -->
</script>
when using
@AfterRender
public void afterRender() {
renderSupport.addScript("urchinTracker();");
renderSupport.addScript("var pp_gemius_identifier = new
String('dw.rQgdz5MHhw1_2bpPIltTI.IjBDjCvnQC0f_bLGdj.v7');");
}
As per http://javascript.about.com/library/blxhtml.htm there are
several possibilities on how to deal with old browsers.
If any JS expert is reading this, how does the code bellow differ from
what Tapestry renders as shown above? The difference is in the
comments and CDATA.
<script type="text/javascript">
<!--//--><![CDATA[//><!--
var pp_gemius_identifier = new
String('dw.rQgdz5MHhw1_2bpPIltTI.IjBDjCvnQC0f_bLGdj.v7');
//--><!]]>
</script>
