Answer 1

Try debugging

for (var i = 0; i < checkBoxList1.length; i++) {
console.log(checkBoxList1[i])
            if (checkBoxList1[i].checked) {
                checkBoxSelectedItems1.push(checkBoxList1[i].value);
                //alert('checked:' + checkBoxSelectedItems1.push(checkBoxList1[i].getAttribute("JSvalue")).value);
                alert('checked - : ' + checkBoxList1[i].value)
            }
        }

Check to see id console.log() gives you any information about the object by pressing F12 on console window. Install firebug plugin for Firefox.

Try this :

<script type = "text/javascript">

function GetCheckBoxListValues(chkBoxID)
{
    var chkBox = document.getElementById('<%= cblHotelFacility.ClientID %>');
    var options = chkBox.getElementsByTagName('input');
    var listOfSpans = chkBox.getElementsByTagName('span');
    for (var i = 0; i < options.length; i++)
    {
        if(options[i].checked)
        {
            alert(listOfSpans[i].attributes["JSvalue"].value);
        }
    }
}


</script>

I'm new in javascript

may this code help you

function CheckBoxCheckOrNot(jobskill) {
var c = document.getElementById(jobskill).getElementsByTagName('input');
for (var i = 0; i < c.length; i++) {
    if (c[i].type == 'checkbox') {

        if (c[i].checked) {
            alert('checkbox checked');


        }
        else {
