hi jean
thanks for the response.but what will happened to the render part in the
"replace -- with < & >
--input type="text" name="t1"
tal:content="structure python:form.t1.render(t1)" size="10" value="0" /--
"
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
--input type="text" name="t1"
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">
function addition(arg1,arg2,arg3)
{
var added = parseInt(arg1) + parseInt(arg2);
arg3.value = added;
}
plz help me
thanks

So please: no cross posts or HTML encoding.
Regarding your question. You send code like:
"""
t2 request/t2|nothing;
t3 request/t3|nothing">
[input] 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:
"""
[input] onchange="replaced by TAL"
tal:attributes="onchange string:addition(${t1}.value,
${t2}.value,
${t3})"
"""
