RE: [Zope] How to Use Javascript returns in DTML tags

23 Oct 2001

      Sounds to me like your trying to make a client side language pass info to a
server-side language. Simply put, you can't do it.

First thing is that the server-side does its thing and then sends that info
to the client's browser. After that, its done! You have to generate a new
request for the server to do anything else.

Javascript runs client-side and after the server has completed its job.

Subject: [Zope] How to Use Javascript returns in DTML tags
I am trying to simply use the return (rfqNumber) from a
Javascript script as
a variable in a DTML tag (see code below).  I've also tried placing the
Javascript code in-line to the DTML, as well as trying to
encapsulating the
script in a DTML method.  None of this seems to work.  Yes, I am
fairly new
to DTML (and Zope, for that matter).  I have seen articles on how to pass
arguments from DTML to Javascript functions, but not on how to use
Javascript returns in DTML.  Can anyone point, push, or drag me
in the right
direction?
Thanks in advance for any help.
<SCRIPT LANGUAGE=JAVASCRIPT>
   <!--
      function GetRFQNumber{
rfqNumber=parent.frames('fraQuoteRequest').document.all['QUOTEREQU
EST'].inne
rText;
         return rfqNumber;
      }
   -->
</SCRIPT>
<!--FORM ID="GetQuoteForm" ACTION="Quote_html"-->
      <H3>
         <dtml-with siteMethods>
            Quote:
            <dtml-let DNS=dbDNS UID=dbUID PWD=dbPWD>
               <SELECT NAME="selQuote" SIZE=1>
                  <dtml-in expr="dataAccess(DNS, UID, PWD, 'SELECT
quoteNumber FROM qt_quotes_t,
                    qt_quoteReqs_t WHERE qt_quotes_t.quoteReqID =

                    qt_quoteReqs_t.rfqNumber = ' + _.chr(39) + rfqNumber +
