multidimensional name-attribute and javascript

[Ivan]

In my HTML forms (created by PHP) for attribute
names I have been using multidimensional arrays as illustrated
in the following:

<table>
<tr>
<td> ID </td>
<td> [1661] <input TYPE=hidden Name=frm_s[0][0] Value=1661></td>
<td> [1662] <input TYPE=hidden Name=frm_s[1][0] Value=1662></td>
<td> [1663] <input TYPE=hidden Name=frm_s[2][0] Value=1663></td>
</tr>
<tr>
<td> Name </td>
<td><input TYPE=text NAME=frm_s[0][1] ></td>
<td><input TYPE=text NAME=frm_s[1][1] ></td>
<td><input TYPE=text NAME=frm_s[2][1] ></td>
</tr>
<tr>
<td> Address </td>
<td><input TYPE=text NAME=frm_s[0][1] ></td>
<td><input TYPE=text NAME=frm_s[1][1] ></td>
<td><input TYPE=text NAME=frm_s[2][1] ></td>
</tr>
</table>

and PHP can deal with these multidimensional attributes as
multidimensional variables. However, I find the need to
deal with user input in these forms on the client side and
I cannot figure out how to access such variable names in
javascript.

Has anyone any ideas?

Thank you for your time.

Whatever name you use in HTML, with JavaScript you use
document.forms['formname'].elements['elementname']
to access the control object e.g.
document.forms['formname'].elements['frm_s[0][0]']
Instead of using a string literal inside of the square brackets you can
of course use any Javascript expression constructing that string e.g.
with loop variables i and j
document.forms['formname'].elements['frm_s[' + i + '][' + j + ']']
