get this element placement within parent

BubikolRamios · 11-11-2012, 12:29 PM

Code:

<table>
  <td>
  </td>
  <td onclick = "somefunction (this);">
  </td>
  <td>
  </td>
</table>

Is it possible that somefunction would return 1 (via parentNode.getelementsbytagname), as this is second td within table ?
No id's, no nothing on elements inside table.

Code:

 
<script>
function somefunction(el){
    var count=0;
    var nodes=el.parentNode.getElementsByTagName(el.tagName);
        while(nodes[count++])
            if(nodes[count-1] === el) 
               alert(count-1);
};
 
</script> 
<body>
<table> <td> </td> <td onclick = "somefunction (this);"> clickMe </td> <td> </td> </table>
</body>
