i have the following html code :

 <FORM name=frmmail>
 <input id="dochtmlContent" type="hidden" name="dochtmlContent" value="oldValue"/>
 <script>document.dochtmlContent="newValue"</script>
 </FORM>

and later on in a javascrip function (which is called upn submit):

     alert(document.dochtmlContent);
     document.frmmail.method = "post";
     document.frmmail.ENCTYPE = "application/x-www-form-urlencoded";
     document.frmmail.action = "/myServlet"; 
     document.frmmail.submit();

Basically, I am declaring a hiden variable, changing its value and submitting it. The issue is, while I see an alert box displaying "newValue", when I submit it, my servlet recieves the "oldValue" for the dochtmlContent parameter.

Can someone suggest whats wrong here.
