to print the value from a javascript function

[divya chamarti]

can any body tell me how to tak ethe value from javascript function and print it on html page

[Christophe Verré]

print which value ?

[Ulf Dittmer]

Something like this:

<script language="JavaScript">
    var field = "value";
 
    document.writeln("field=" + field);
</script>

If the page has been completely rendered (i.e., you want to do this at a later point in time, e.g. during an event handler) you'll have to use DOM to set or change text on a page.

Why dont you store the value in the Session, if you want it across jsps?

There is no such thing as session in JavaScript so I think the last comment is confusing things.

Why don;t you just access the field when you need it and not when there is an onchange?

var sel = document.forms[0].selectName;
var val = sel.options[sel.selectedIndex].value;

If you want to do it onchange than you need to set it to a glable variable. If you need the value on the server side, submit the form.
