Question

I am calling this function on event onClick

function openGrpLifeStmtReport (busnsourceid,treatyId,policyid,productid,schemename,periodfrom,periodto,plcyeffdtfrom,polcyeffto,benType,exportTo,jasperName,jasperNamesum,reportvar1,reportvar2,reportvar3,reportvar4,userloged,clientId)
{

    document.getElementById("reportvar1").value = document.getElementById("busnsourceid").value;
    document.getElementById("reportvar2").value = document.getElementById("treatyId").value;
    document.getElementById("reportvar4").value = document.getElementById("productid").value;
    var Busnsourceid=document.getElementById(busnsourceid).value;
    var TreatyID=document.getElementById(treatyId).value;
    var PolicyID=document.getElementById(policyid).value;
    var ProductID=document.getElementById(productid).value;
    var SchemeName=document.getElementById(schemename).value;
    var PeriodFrom=document.getElementById(periodfrom).value;
    var PeriodTo=document.getElementById(periodto).value; 
    var plcyeffdtfrom=document.getElementById(plcyeffdtfrom).value;
    var polcyeffto=document.getElementById(polcyeffto).value;
    var BenType=document.getElementById(benType).value;
    var exportTo=document.getElementById(exportTo).value;
    var jasperName=document.getElementById(jasperName).value; 
    var jasperNamesum=document.getElementById(jasperNamesum).value; 
    var userloged=document.getElementById(userloged).value;
    var clientId=document.getElementById(clientId).value;
    var reportvar3; 
    var disorderby = document.getElementById("orderBy").value;
    var disgroupby = document.getElementById("groupBy").value;
            for (var form=0; form < document.forms.length; form++) 
        {
         var what = document.forms[form];
         for (var i=0, j=what.elements.length; i<j; i++) 
         {
           if (what.reportvar3[i].checked == true) 
            {
                reportvar3 = what.reportvar3[i].value;          
                break;  
            }
         } 
        }

        var url = "./GroupLifeAdvRep.do?action=customAction&innerAction=printGrpLifeRep&CedantCode="+Busnsourceid+"&TreatyID="+TreatyID+
            "&Policy Id="+PolicyID+"&ProductID="+ProductID+"&SchemeName="+SchemeName+"&PeriodFrom="+PeriodFrom+"&PeriodTo="+PeriodTo+"&plcyeffdtfrom="+plcyeffdtfrom+"&polcyeffto="+polcyeffto+"&BenType="+BenType+"&exportTo="+exportTo+"&jasperName="+jasperName+"&jasperNamesum="+jasperNamesum+"&reportvar1="+reportvar1+"&reportvar2="+reportvar2+"&reportvar3="+reportvar3+"&reportvar4="+reportvar4+"&disorderby="+disorderby+"&disgroupby="+disgroupby+"&userloged="+userloged+"&clientId="+clientId;

}

the code calling this function

<a href="#"><img src="Images/generatereport_btn.gif" alt="generatereport" border="0" onclick="openGrpLifeStmtReport('busnsourceid','treatyId','policyid','productid','schemename','periodfrom','periodto','plcyeffdtfrom','polcyeffto','benType','exportTo','jasperName','jasperNamesum','reportvar1','reportvar2','reportvar3','reportvar4','userloged','clientId')"/></a> 

Answer 1

Issues:

1. IE allows getElementById to be called on fields that have only NAME, no other browsers will allow that, so make sure the form fields have IDs
2. you are calling this onclick of an image inside a link. Not a recommended way. Use onclick of the link and return false
3. Spaces in the OPEN parameters - they can break stuff in some browsers - also target may be a reserved word try

:

function openGrpLifeStmtReport (busnsourceid,treatyId,policyid,productid,schemename,periodfrom,periodto,plcyeffdtfrom,polcyeffto,benType,exportTo,jasperName,jasperNamesum,reportvar1,reportvar2,reportvar3,reportvar4,userloged,clientId) {

document.getElementById("reportvar1").value = document.getElementById("busnsourceid").value;
document.getElementById("reportvar2").value = document.getElementById("treatyId").value;
document.getElementById("reportvar4").value = document.getElementById("productid").value;
var Busnsourceid=document.getElementById(busnsourceid).value;
var TreatyID=document.getElementById(treatyId).value;
var PolicyID=document.getElementById(policyid).value;
var ProductID=document.getElementById(productid).value;
var SchemeName=document.getElementById(schemename).value;
var PeriodFrom=document.getElementById(periodfrom).value;
var PeriodTo=document.getElementById(periodto).value; 
var plcyeffdtfrom=document.getElementById(plcyeffdtfrom).value;
var polcyeffto=document.getElementById(polcyeffto).value;
var BenType=document.getElementById(benType).value;
var exportTo=document.getElementById(exportTo).value;
var jasperName=document.getElementById(jasperName).value; 
var jasperNamesum=document.getElementById(jasperNamesum).value; 
var userloged=document.getElementById(userloged).value;
var clientId=document.getElementById(clientId).value;
var disorderby = document.getElementById("orderBy").value;
var disgroupby = document.getElementById("groupBy").value;

var reportvar3=""; 
var reportvars = document.getElementsByName("reportvar3");
for (var i=0; i < reportvars.length; i++) {
  if (reportvars[i].checked) {
    reportvar3 = reportvars[i].value;          
    break;  
  } 
}

var url = "./GroupLifeAdvRep.do?action=customAction&innerAction=printGrpLifeRep&CedantCode="+Busnsourceid+"&TreatyID="+TreatyID+
        "&Policy Id="+PolicyID+"&ProductID="+ProductID+"&SchemeName="+SchemeName+"&PeriodFrom="+PeriodFrom+"&PeriodTo="+PeriodTo+"&plcyeffdtfrom="+plcyeffdtfrom+"&polcyeffto="+polcyeffto+"&BenType="+BenType+"&exportTo="+exportTo+"&jasperName="+jasperName+"&jasperNamesum="+jasperNamesum+"&reportvar1="+reportvar1+"&reportvar2="+reportvar2+"&reportvar3="+reportvar3+"&reportvar4="+reportvar4+"&disorderby="+disorderby+"&disgroupby="+disgroupby+"&userloged="+userloged+"&clientId="+clientId;
window.open(url,"_blank","width=850,height=600,top=75,left=75,scrollbars,resiza‌​ble");
return false; // cancel link
