[Zope] Zope and Javascript

[David Hassalevris]

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>

<form ... >
<input type="hidden" name="some_switch" value="="&dtml-someVar">
<-----------------------------  DTML
</form>

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