Dear All,
I have form where I add dynamic html element as below. In the php code (getMasterList.php) via ajax I have built the full drop down list. So when I post the form in IE when I do like this $masterID=$_POST['masterID']; I am able to capture the form value. But in both firefox and chrome it shows me empty. Any solution please?

PHP Code:
function getMaster(entID,nextElement)
{
var 
table document.getElementById('myTable');               
var 
rowCount table.rows.length
//alert("Row count : "+rowCount);
  
if(rowCount>2)
{            
    for(var 
i=2i<rowCounti++) 
    {                 
        var 
row table.rows[i];                 
                             
            
table.deleteRow(i);                     
            
rowCount--;                     
            
i--;                 
    }
}

differentiator=Math.floor(Math.random()*50000);
//if (str=="")
 // {
 // document.getElementById("cbTrailerList").innerHTML="";
 // return;
 // } 
if (window.XMLHttpRequest)
  {
// code for IE7+, Firefox, Chrome, Opera, Safari
  
xmlhttp=new XMLHttpRequest();
  }
else
  {
// code for IE6, IE5
  
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (
xmlhttp.readyState==&& xmlhttp.status==200)
    {
        
//alert("Test : "+xmlhttp.responseText);
    //document.getElementById("cbTrailerList").innerHTML=xmlhttp.responseText;    
      
var x=document.getElementById('myTable').insertRow(2); 
      var 
y=x.insertCell(0); 
      var 
z=x.insertCell(1); 
      
y.innerHTML="<label class=description for=element_1>Master <font color='red'>*</font></label> "
      
z.innerHTML=xmlhttp.responseText;
      var 
a=document.getElementById('myTable').insertRow(3); 
      var 
b=a.insertCell(0); 
      var 
c=a.insertCell(1); 
      
b.innerHTML=""
      
c.innerHTML="<p class=error id='masterIDError'>"
    
     if(
nextElement=="trailer")
      {
       
getTrailer(entID);
      }
     else
      {
       
getSlaves(entID);
      }
    }
    
  }
xmlhttp.open("GET","getMasterList.php?e="+entID+"&d="+differentiator,true);
xmlhttp.send();
