2 dimensional array

[indu yeturu]

Am creating a simple dynamic table like this,

      var tb=document.getElementById("t");
      var lastrow = tb.rows.length;
      var elem=document.getElementsByTagName("p").length;
      var row = tb.insertRow(lastrow);
      
      var name=row.insertCell(0);
      var dname=document.createElement("input");
      name.appendChild(dname);
      
      var cls=row.insertCell(1);
      var dclass=document.createElement("input");
      cls.appendChild(dclass);

and I created dynamic 2 dimensional array because I need to push the elements of the above table into particular arrays based on the [row,column] indices.
For that my code is ::::

             rowarray = new Array();

             for(i=0;i<rowlength;i++)
             {
                rowarray[i]=new Array();

                  for(j=0;j<elem_length;j++)
                  {
                     alert(rowarray[i][j]);
                   }
             }

    

Here am trying to display the value of each element,but it displays as 'undefined'.... What is the way to print the values of elements here?
thanks

You never assigned it a value so it is undefined. What would you expect it to alert?

There am expecting the value of the cell[i][j] where

 
rowlength = tableref.rows.length -- dynamic row.  
no_ofelements = document.getElementsByTagName("p").length;
        

   

i = 0 to rowlength
j = points to columns in the table(name,columns) j=0 to no.elements in the table;
no.of elements in the table is elements

The sample HTML :::

    
 <form name="form">
      <table id="t"> <tr>
                 <td><p><input type="text" name="name"></p></td>
                 <td><p><input type="text" name="class"></p></td></tr>
        </table>
                  <input type="button" value="Add" onclick="addrow()">
                  <input type="button" value="Show" onclick="show()">
</form>

 

Sothat I tried to alert the values of the elements which I entered at specific row,column locations

And how are you sticking those values into the newly created arrays? You sample code shows nothing but creating arrays and alerting an empty cell.
