Question

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 ?

javascript

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

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title></title>
  
</head>
<body>

<table id="MainTable" width=100% style="height:100%" border=0>
<tr><td id="MainTD"></td></tr>
</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();
    </script>
</body>
</html>

serkan, i used your code.

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.
