getting values of multidimensiona l HTML select

[BB]

Hello,

I have a HTML form containing multidimensiona l selects listing
equipments and their quantitites. This allow the users to select the
kind of equipment and quantitites they would like to book. Upon
onChange select event I would like to parse the data into a
multidimensiona l Javascript array in order to check equipment
availability for booking. But I can't figure out how to parse and upon
JS HTML DOM reference I am not even sure it's possible.

For example one select lists available cameras:

<tr>
<td>
<label>Digita l camera</label>
</td>
<td>
<select name="camera[]" size="1" >
<option value="0" >0</option>
<option value="1" >1</option>
</select>
</td>
</tr>
<tr>
<td>
<label>Video camera</label>
</td>
<td>
<select name="camera[]" size="1" >
<option value="0" >0</option>
<option value="1" >1</option>
</select>
</td>
</tr>

For info, in my real situation, this select is dynamically populated
using PHP querying a database. All the booking processing is done with
PHP after the form has been posted. I now need to do some pre-flight
test and guess JS is the right guy to do so.

So, is there anyone with helpful ideas for parsing this
multidimensiona l HTML select into a multidimensiona l JS array?

Thank you,

[Lee]

There is no such thing as a multidimensiona l HTML select.

<script type="text/javascript">
function booker() {
var book = document.forms['form1'].elements['camera[]'];
var max = book.length;
var datas = '';
for(var i=0; i<max; i++) {
datas += book[i].options[book[i].selectedIndex].value;
if(i<(max-1)) { datas += ','; }
}
return datas;
}
</script>

For example one select lists available cameras:

<form name="form1">
<input type=button value="to see"
onclick="alert( 'choice = '+booker());" >
<table>

<tr>
<td>
<label>Digita l camera</label>
</td>
<td>
<select name="camera[]" size="1" >
<option value="0" >0</option>
<option value="1" >1</option>
</select>
</td>
</tr>
<tr>
<td>
<label>Video camera</label>
</td>
<td>
<select name="camera[]" size="1" >
<option value="0" >0</option>
<option value="1" >1</option>
</select>
</td>
</tr>

</table>
</form>
