     $.getJSON('combo1.jsp', {count : this.value}, function(responseData) {
     var splitValues = responseData.name.split(/,/);
     $("#combo1").empty().append ("<option>please select</option>");
    for (var idx in splitValues) {

    <select id="combo" name="count">
         <option value="">please select</option>
          <option value="a">A</option>
     </select> 

    //second combo box

    <select id="combo1" name="combo1Val">
         // i am getting only "5" here, but i want to show 1,2,3,4,5 as in drop down list
     </select> 
    </body>

combo1.jsp

    <%
    String count=request.getParameter("count");// by onchange event of first combo, i am 
    getting value "a" here
    if(count.equalsIgnoreCase("a")){
    // in my db there are 5 values i.e. 1,2,3,4,5 for single value "a", but while   
    populating in second combo i am getting only one value "5", how? please ignore my db   
    connection in jsp

    1,2,3,4,5 as drop down items in second combo box?
    // retrieveing 5 datas(1,2,3,4,5) from db where name =a
     while(rs.next()){
          t1=(String)(rs.getString(1));// there are 5 values in db relating to "a", but i  
    am getting only last value i.e. "5" in second combo
           }
           arrayObj.put("name",t1);
              response.setContentType("application/json");
          response.getWriter().write(arrayObj.toString());
          }
