checkboxes php and javascript

[mailtome]

hi
I am generating a set of dynamic checkboxes via php.
I have to check that the uer should atleast check one checkbox. When there are more then 1 checkbox my javascript works but if there is only one check box then my javascript doesnt works. My code is
<script>
function deletecheck()
{

for (i=0;i<document.form.elements['projectChecked[]'].length;i++)
{ if(document.form.elements['projectChecked[]'].checked==true)
{
return true;
}
}
alert ("Please select a project to delete");
return false;

}

</script>
<form ......onsubmit='return deletecheck();'>
<?php
foreach(.....)
{
echo "<input type='checkbox' name='projectChecked[]' value='".$projectName."' >";
}
?>

Flip your script:

<?php
$i=0; 
foreach(.....) 
{ 
echo "<input type='checkbox' name='projectChecked[]' value='".$projectName."' >"; 
$i++
} 
?>
<script> 
function deletecheck() 
{ 
var i;
for (i=0;i<<?php echo $i; ?>;i++) 
{ 
if(document.getElementById['projectChecked[i]'].checked==true) 
{ 
return true; 
} 
} 
alert ("Please select a project to delete"); 
return false; 
} 
</script>

Not % sure... guess this should do it

Good Luck
