Check/Uncheck all checkboxes with name as 'name[]'

Hi, since sometime I'm stuck in a problem where I want to check or
uncheck all the checkboxes. If I'm choosing name for the checkbox
array as 'chkbx_ary' then I'm able to check/uncheck all the checkboxes
(code pasted below). But if name of the checkbox array is
'chkbx_ary[]' then it's failing. I want the name to be 'chkbx_ary[]'
because I want to access this array at server side.
Though one may not require to see php part but I'm still pasting the
code.

<script language="JavaScript" type="text/javascript">
function CheckAll(field)
{
for (loop=0; loop < field.length; loop++)
{
field[loop].checked = true;
}
}

function UnCheckAll(field)
{
for (loop=0; loop < field.length; loop++)
{
field[loop].checked = false;
}
}
</script>

<?php
echo '<form name="TestSelect_Form" method="GET" action="TestList.php"
enctype="text/plain" style="margin:0px">
<input type="radio" name="SelectOrNot" value="Select_All"
onClick="CheckAll(document.TestSelect_Form.SelectM odule)"
style="position:absolute;left:290px;top:140px;z-index:6">
<input type="radio" name="SelectOrNot" value="Uncheck_All"
onClick="UnCheckAll(document.TestSelect_Form.Selec tModule)" checked
style="position:absolute;left:400px;top:140px;z-index:7">';
$file_name = "CONF/testselect.txt";
$fp_TstSlct = fopen("$file_name", "r") or die("Some error occurred
while opening 'testSelect.txt");
$TopPos = 170;
while(!feof($fp_TstSlct))
{
$TstSlct_data = fgets($fp_TstSlct);
preg_match_all("/([#]*)(.*)\s(\d+)\s*[;#]*(.*)/", $TstSlct_data,
$match, PREG_PATTERN_ORDER);
if ( $match[2][0] != NULL ) { //Checking whether module is present
or not. May be only comments have been put. For. e.g.
###################DSL HOME#########
if ( $match[1][0] == NULL ) { //Checking if line is starting with
'#' or not
echo '<input type="checkbox" name="SelectModule[]" value=' .
$match[2][0] . ' checked="checked" style="position:absolute;left:
90px;top:' . $TopPos . 'px">';
} else {
echo '<input type="checkbox" name="SelectModule[]" value=' .
$match[2][0] . ' style="position:absolute;left:90px;top:' . $TopPos .
'px">';
}

echo '<div id="text3" style="position:absolute; overflow:hidden;
left:130px; top:' . $TopPos . 'px; width:79px; height:16px"><div
class="wpmd">';
echo '<div><font face="Arial">' . $match[2][0] . '</font></div>';
echo '</div></div>';

$TopPos = $TopPos + 25;
}
}
fclose($fp_TstSlct);

echo '<input name="ConfigureTestList" type="submit" value="Next"
style="position:absolute;left:326px;top:403px;z-index:16">
</form>

<div id="text1" style="position:absolute; overflow:hidden; left:
265px; top:118px; width:69px; height:18px; z-index:9"><div
class="wpmd">
<div><font class="ws12" face="Arial">Select All</font></div>
</div></div>

<div id="text2" style="position:absolute; overflow:hidden; left:
371px; top:118px; width:85px; height:18px; z-index:10"><div
class="wpmd">
<div><font class="ws12" face="Arial">Uncheck All</font></div>
</div></div>';
?>

Please someone suggest the solution as I'm totally stuck.
Thanks a lot in advance.

document.forms[0].elements['chkbx_ary[]'];

document.forms['TestSelect_Form'].elements['chkbx_ary[]'];

if several checkboxes of same name
that will return [object NodeList]

ordinary checboxes don't wear same name ...
how do you recognize one from the other ?

some tests :

var chc = document.forms['TestSelect_Form']['chkbx_ary[]'];
alert( chc[0].value);
alert( document.forms['TestSelect_Form']['chkbx_ary[]'][0].value );
for(var i=0, n=chc.length; i<n; i++)
alert(chc[i].value)
var t = '';
for(var i=0, n=chc.length; i<n; i++)
t += chc[i].name + '\'s value = ' + chc[i].value +'\n';
alert(t);

because I want to access this array at server side.
Though one may not require to see php part but I'm still pasting the
code.
onclick="CheckAll(document.TestSelect_Form['SelectModule[]'])
or (because it is in the form) :
onclick="CheckAll(this.form['SelectModule[]']);
<script language="JavaScript" type="text/javascript">
function CheckAll(field)
{
for (loop=0; loop < field.length; loop++)
{
field[loop].checked = true;
}
}

function UnCheckAll(field)
{
for (loop=0; loop < field.length; loop++)
{
field[loop].checked = false;
}
}
</script>

<?php
please give the result in html !

where is the problem ? which line(s) ?
Please someone suggest the solution as I'm totally stuck.

You can't use :
document.TestSelect_Form.chkbx_ary[]
because brackets are of JS language
so you'll do :
document.TestSelect_Form.elements['chkbx_ary[]']
or :
document.getElementsByName('chkbx_ary[]');
to get the collection of checkboxes named 'chkbx_ary[]'
