I have a table structure like this..
<form name="kuchbhi">
<table id="x">
<tr name="alpha">
<td><input name="a" type="checkbox"></td>
<td><input name="b" type="checkbox"></td>
</tr>
<tr name="beta">
<td><input name="a" type="checkbox"></td>
<td><input name="b" type="checkbox"></td>
</tr>
</table>
<table id="y">
<tr name="alpha">
<td><input name="a" type="checkbox"></td>
<td><input name="b" type="checkbox"></td>
</tr>
<tr name="beta">
<td><input name="a" type="checkbox"></td>
<td><input name="b" type="checkbox"></td> <!--This one-->
</tr>
</table>
</form>
Now, I have only 2 info (tr name) and (input name). For example I have (beta, a). Now I want to put a check on that checkbox (on the second table named y). How to select that checkbox?
