[jQuery] Ignoring click events in cells

[Andyk]

I have a table, which contains some data aswell as a checkbox:

<tr id="14373">
 <td><input type="checkbox"/></td>
 <td>...</td>
 <td>...</td>
</tr>
Each row contains an id, and I want to call a function based on the
click event:

            $("tr").click(function() {
                alert($(this).attr("id"));
            });

However, checking/unchecking the checkbox in each row also triggers
the event. Is there anyway of preventing this?
