[HTML]<form method="post" action="send.jsp">

in this case I would use getElementsByTagName("input") and loop through the result array. Another way is to use the nextSibling/previousSibling/parentNode/childNodes properties of the node object.

I hope this will help u out

[HTML]<html>
<head>
<script type="text/javascript">
function doThis(ths)
{
var x=(ths.id).toString();
var i=x.indexOf('r');
var num = parseInt(x.substring((i+1),x.length));
var table = document.getElementById("myTable");
var row = table.rows[num-1];
var first=row.cells[0].innerHTML;
var second = row.cells[1].innerHTML;
document.getElementById('myText1').value=first;
document.getElementById('myText2').value=second;
}
</script>
</head>
<body>
<p>Click on any Element in the Table</p>
<br/>
<table id="myTable" border="1" cellpadding="5" cellspacing="5">
<tr id="tr1" onclick="doThis(this)">
<td>Hai1</td><td>Hello1</td>
</tr>
<tr id="tr2" onclick="doThis(this)">
<td>Hai2</td><td>Hello2</td>
</tr>
<tr id="tr3" onclick="doThis(this)">
<td>Hai3</td><td>Hello3</td>
</tr>
<tr id="tr4" onclick="doThis(this)">
<td>Hai4</td><td>Hello4</td>
</tr>
<tr id="tr5" onclick="doThis(this)">
<td>Hai5</td><td>Hello5</td>
</tr>
</table> <br/>
<input type="text" id="myText1">     <input type="text" id="myText2">
</body>
</html>[/HTML]
This will be helpful if the data is within td
