[RESOLVED] Using OnClick to display table cell

[deonnel]

When I click on a table cell the alert ALWAYS gives me "1". Why?

<table border="1">
<?php for ($i=1; $i<=5; $i++) { ?>
<tr id="tr_1" onclick="alert(document.getElementById('td_1').innerHTML)">
<td id="td_1"><?php echo $i; ?> </td>
</tr>

Because you are assigning the same ID to each <td> (which is invalid HTML), so you are getting the value for the first element found with that ID.

<table border="1">
<?php for ($i=1; $i<=5; $i++) {
echo "<tr id='tr_$i' onclick=\"alert(document.getElementById('td_$i').innerHTML)\">\n";
echo "<td id='td_$i'>$i</td>\n";
echo "</tr>\n";
} ?>
</table>
