hi

my html form contains a table tag <table id="MainTable">.

i would like to populate this table using a javascript function.
my probllem is that i created a table that contains another table inside on of the <td> tags. i tried to write the most basic code:

var myTable = document.createElement('tbody');
        var row1 = document.createElement('tr');
          var col1 = document.createElement('td');
            var but1 = document.createElement('input');
                but1.setAttribute('type','button');
                but1.setAttribute('value','button1');
                
              col1.appendChild(but1);
            row1.appendChild(col1);
          myTable.appendChild(row1);
          
          var row2 = document.createElement('tr');
            var col2 = document.createElement('td');
              var nestedTbl = document.createElement('tbody');
                var row3 = document.createElement('tr');
                  var col3 = document.createElement('td');     
                    var but2 = document.createElement('input');
                        but2.setAttribute('type','button');
                        but2.setAttribute('value','button2');
                      
                      col3.appendChild(but2);
                    row3.appendChild(col3);
                  nestedTbl.appendChild(row3);
                
                col2.appendChild(nestedTbl);
              row2.appendChild(col2);
             myTable.appendChild(row2);            
      
      MainTable.appendChild(myTable);

when i run the javascript function it creates the table 'MyTable' and shows the first button but ignores completely from the inner table.

is there a way to achieve my goal ?

yes. here is it:

<%@ Page Language="C#" MasterPageFile="~/Masters/MainMaster.Master" AutoEventWireup="true"
    CodeBehind="Login.aspx.cs" Inherits="Site.Login" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

<table id="MainTable" width=100% style="height:100%" border=0>

</table>

<script type="text/javascript">

window.onload = Create_Page;

function Create_Page()
{
        var myTable = document.createElement('tbody');
        var row1 = document.createElement('tr');
          var col1 = document.createElement('td');
            var but1 = document.createElement('input');
                but1.setAttribute('type','button');
                but1.setAttribute('value','button1');
                
              col1.appendChild(but1);
            row1.appendChild(col1);
          myTable.appendChild(row1);
          
          var row2 = document.createElement('tr');
            var col2 = document.createElement('td');
              var nestedTbl = document.createElement('tbody');
                var row3 = document.createElement('tr');
                  var col3 = document.createElement('td');     
                    var but2 = document.createElement('input');
                        but2.setAttribute('type','button');
                        but2.setAttribute('value','button2');
                      
                      col3.appendChild(but2);
                    row3.appendChild(col3);
                  nestedTbl.appendChild(row3);
                
                col2.appendChild(nestedTbl);
              row2.appendChild(col2);
             myTable.appendChild(row2);            
      
      MainTable.appendChild(myTable);
}
</script>
</asp:Content>

here is the working version for you, i set the table borders for you to see it clearly.

</table>

  <script type="text/javascript">
      function deneme() {

          var myTable = document.createElement('table');
          myTable.border = 1;
          var row1 = myTable.insertRow();
          var col1 = row1.insertCell();
          var but1 = document.createElement('input');
          but1.setAttribute('type', 'button');
          but1.setAttribute('value', 'button1');

          col1.appendChild(but1);


          var row2 = myTable.insertRow();
          var col2 = row2.insertCell();
          var nestedTbl = document.createElement('table');
          nestedTbl.border = 1;
          var row3 = nestedTbl.insertRow();
          var col3 = row3.insertCell();
          var but2 = document.createElement('input');
          but2.setAttribute('type', 'button');
          but2.setAttribute('value', 'button2');

          col3.appendChild(but2);
          

          col2.appendChild(nestedTbl);
         

          MainTD.appendChild(myTable);
      }
      deneme();

its working great.
thank you very much.

you are refering to mine? if so , i need reputation, rashakil fool keep deducing my reputation points :) i need some protection.

Comments
Take this rubber shield :D
ALWAYS use protection! You don't want to have babies before you're ready, do you?

serkan, i used your code.

yeah that is why i said add to my reputation because people keep reducing my reputation because of my non-technical threads like the one i said cheating must be supported, after a while posters would thing that my disreputation comes from the technical knowledge, which is not the case, and wont take my posts seriously.
