my javascript function is below where I am creating the 2 textboxes dynamically each time when the addRow() function is called on button click.Also,I am setting name attribute for each textbox dynamically.but I am not able to access these textbox values from servlet and getting null value as output.

<html>
<head>
<script>
var count=1;
function addRow()
{


var table = document.getElementById('table');
    var rowCount = table.rows.length;
    var row = table.insertRow(rowCount);
    var cell1 = row.insertCell(0);
    var element1 = document.createElement("input");
    element1.type = "text";
    element1.name = "item "+ count;
   // document.write(element1.name);
    cell1.appendChild(element1);     

    var cell2 = row.insertCell(1);
    var element2 = document.createElement("input");
    element2.type = "text";
    element2.name = "amount" + count;
    cell2.appendChild(element2);

    var cell3 = row.insertCell(2);
    cell3.innerHTML = ' <input type="button" value="Edit" onclick="editRow(this)"/><input type="button" value="Delete" onclick="deleteRow(this)"/>';
    cell3.setAttribute("style", "display:none;");

    var cell4 = row.insertCell(3);
    cell4.innerHTML = '<input type="button" value="Save" onClick="saveRow(this)">';


    document.listform.hfield.value=rowCount;
    count++;



}

  • Can you show how you are trying to read the values? Have you tried using array checkboxes (I think it is something like name="amount[]") – porfiriopartida Sep 13 '13 at 05:43
  • I was reading value in servlet using request.getParameter(amount[1]) but it is giving me null value. – user2773665 Sep 13 '13 at 05:55
  • Then update your question by adding the code. Seems that you are using element1 element2 as names and they can't be accessed by element[1]; you must rename your HTML name to array like if you want to use element[i].
