hi jean

thanks for the response.but what will happened to the render part in the

"replace -- with < & >

"

 this will bring the field t1 from the formulator .now when  i place the javascript attribute called addition(t1).it doesn't work.

i had actually written

tal:content="structure python:form.t1.render(t1)" size="10" value="0" /-- onchange="addition(t1.value,t2.value,t3)"--

--input type="text" name="t2"

tal:content="structure python:form.t2.render(t2)" size="10" value="0" /-- onchange="addition(t1.value,t2,value,t3)"--

--input type="text" name="t3"

tal:content="structure python:form.t3.render(t3)" size="10" --

t1,t2 (textfields )are defined in the formulator .

how do i make it work? I actually understand that after rnning a file that takes elements from the formulator, it names it as field_t1,field_t2,

is there any solution or alternative

my actual requirement is that , using the values entered in t1 & t2 i shud add them & put in the text box t3 also defined in the formulator .

my javascript function states that

<script type="text/javascript">

plz help me

thanks

Hi Exteam

In the footer of every mail from the zope lists, you may see this

So please: no cross posts or HTML encoding.

Regarding your question. You send code like:

"""


onchange="addition(t1.value,t2.value,t3)"
"""

It looks as though you want to use TAL-defined variables (t1, t2, t3)
in your javascript. This is how to do that:

"""
onchange="replaced by TAL"
tal:attributes="onchange string:addition(${t1}.value,
${t2}.value,
${t3})"
"""
