Hello Experts,
I am returning comma separated columns and pipe separated in the Ajax Response.
I have a SELECT tag in the page where user can select which column they want to use in the report,
How can I handle this !
Please advice.

Like this:

<script>
function yourResponseFunction(){
  var theResponse = http.responseText;
  var theColumnNumber = document.forms[0].yourSelectName.value; // option value has to be column Number,  first column number zero
  var row = theResponse.split("|");
  for(var i=0;i<row.length;i++){
     var column = row[i].split(",");
     alert("Row"+i+"Column"+theColumnNumber+":  "+column[theColumnNumber]);
  }
}

</script>

Yes, on this page I am doing an ajax call to retrieve details for the records submitted from list_admin.

Attached is the Asp script to process the Ajax request
rURL = RemoteServer & "/xmla/xml_results.asp?DBM=" & SiteName & "&SF1=keyword&ST1=" & ISBNLists							
			xTxt = GetXML(rUrl)
			'parts = Split(XMLField(xTxt, "resultfields", False), chr(28)) 
			parts = Split(XMLField( Replace(xTxt,",","&#44;"), "resultfields", False), chr(28))
            For each p in parts
			   strISBNData = strISBNData &  XMLField(p, "fv_co_name", false) & ","
			   strISBNData = strISBNData &  XMLField(p, "fv_co_address", false) & ","
			   strISBNData = strISBNData &  XMLField(p, "fv_co_descrip", false) & ","
			   strISBNData = strISBNData &  XMLField(p, "fv_co_tel_work", false) & ","
			   strISBNData = strISBNData &  XMLField(p, "fv_pe_name", false) & ","
			   strISBNData = strISBNData &  XMLField(p, "fv_pe_position", false) & ","
			   strISBNData = strISBNData &  XMLField(p, "fv_pe_tel_work", false) & ","
			   strISBNData = strISBNData &  XMLField(p, "fv_ref_no", false) & "|"			   
			next   
			response.Write strISBNData

From your description, you stated that you have a formatted response and a select tag with options. Then your question is "How can I handle this !" What's the problem/goal?

If you are submitting an ajax request you will need a call back function that will receive the response text. You can split that text at the commas and if what you are trying to do is to "rebuild" the <SELECT> then wrap the <select> in some container tag:
<span id="selContainer"><select name="theList">...</select></span>

 and then insert a new html in that span so that it contains the entire <select> (not just the options)

...
 success=function (msg)
  {
    var sel="";
    var data = msg.split("|");
    if( data.length)
    {
    sel = "<select name='theList'>";
    for(var i=0; i < data.length; ++i)
    {
        var t = data[i].split(",")
        sel += '<option value="' + t[0] + '">' + t[1] + '</option>';
   }
    sel+='</select>';
   $("#selContainer").html(sel);
   }
  }
