writing to a give table element

mxa

Hi,
given table :
<table id='t1'>
<tr><td> data1</td><td>data2</td></tr>
</table>

i would like to write a function to write and change data2
( location is fixed ).

function changeme () {

document.write('new data2');

}

how can I focus on 'data2' before calling the above function?
thanks
Michael

Just a note: could also go -

var tbody =
document.getElementById('t1').getElementsByTagName ('tbody').item(0);
var firstrow = tbody.rows.item(0);

Now there's an easy way and a hard way...

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Change Data2</title>

<script type="text/javascript">
function changeme(ele,str) {
var tbl = document.getElementById(ele);
t1.innerHTML = str;
}
</script>

</head>
<body>
<table cellspacing="10">
<tbody style="font:32px tahoma;">
<tr>
<td>data1</td>
<td id="t1">data2</td>
</tr>
</tbody>
</table>

<div onclick="changeme('t1','Here is the new text');" style="
font-family: tahoma;
border: 1px solid blue;
background-color: #ddddee;
width: 20em;">Click here to to change the text</div>
</body>
</html>

I reckon that's the easy way! :-)

Of course, getElementsById is not compatible with older browsers and
innerHTML, whilst well supported, is not part of the official DOM. So
if this is for real web use, let us know and we'll post something a bit
more robust (but it'll take a few more lines of code...)

Believe it or not, the above rubbish worked in Safari. My apologies,
the correct code is below.

<script type="text/javascript">
function changeme(ele,str) {
var d = document.getElementById(ele);
d.innerHTML = str;
}
</script>
