Re: [Zope] Zope and Javascript

      Asad,

I forgot that <dtml-eval> is not a standard product (I use it all the time).
Also ascripts = 0 would not activate the javascript because <dtml-if 0>
doesn't execute.
Sorry about that.

P.S. - you can also use DTML to set hidden HTML <form> fields.  Then inspect
those fields for a value in a JavaScript function, eg
----------------------------------------------------------------------------
-------------------------------------
<script language="Javascript">
function doProcess()
{

   if (document.forms[0].some_switch.value == 'process') {
<--------------------------- java
      alert('test!) ;
      return false ;
   }

</script>

<a href="" onclick="doProcess();return false;">
     <IMG SRC="//btn_left_process" alt="Process" border="0"/></a>
----------------------------------------------------------------------------
--------------------------------

Asad,
Maybe something like this?
<dtml-var standard_html_header>
<h2><dtml-var title_or_id> <dtml-var document_title></h2>
<dtml-eval> ascripts = 0 </dtml-eval>
<dtml-if ascripts>
<SCRIPT LANGUAGE="JavaScript">
<!-- hide from old browsers
alert('howdy')
// end script hiding -->
</SCRIPT>
</dtml-if>
<dtml-var standard_html_footer>

Subject: [Zope] Zope and Javascript
...
I am trying to figure out if there is a way to open a new browser window
when a certain condition is met. A variable would be set to a certain
value and placed in either the REQUEST object or the SESSION attribute
of
the REQUEST object when this condition was met. I know how to do this
part. However, I am having trouble figuring out how I can execute some
Javascript code when this condition is met. In particular, the
Javascript
code should open a new window and display a customized message in this
window. I also have the Javascript code to do this particular task. How
do
I call this Javascript code though? Is it possible to place Javascript
code in a DTML method? If so, then I could call the method when the
condition was
met and this would execute the Javascript code. Any help would be
greatly
appreciated. Thanks.
- Asad
