Try this:
<script type="text/javascript">
$(document).ready(function(){
var ok = '';
$('button').click(function() {
$('#my_form input[type = "checkbox"]').each(function() {
if ( $(this).attr('checked') ) {ok = true}
})
ok ? alert('there is at least one checked') : alert('none checked');
});
});
</script>
</head>
<body>
<form id="my_form" action="" method="get">
<input name="whatever_name1" type="checkbox" value="a" />
<input name="whatever_name2" type="checkbox" value="b" />
</form>
<button type="button">Checked?</button>
</body>
</html>

Assunto: [jQuery] Re: Multiselect listbox
The thing is you will not select a named element by $('.name') but an
element of the class "name".
How does your HTML look like?

Hi!
Thanks for guidance. I have changed JS code as follows. And now it
is totally ignoring the check.
My listbox name is "zonelocation[]" . I have used name with/without
DOT in JQUERY identifier placeholder. The result is same.
/*************************/
var zonelocationVal;
jQuery(.'zonelocation[]').each(function(){
if(jQuery('.zonelocation[]').attr('checked') == 'checked'){
zonelocationVal = true;
}
});
/*************************/
What Iam doing wrong?
Thanks in advance.
