        if(this.checked) { // check select status
            $('.btn-chk').each(function() { //loop through each checkbox
                this.checked = true;  //select all checkboxes with class "checkbox1"               
            });
        }else{
            $('.btn-chk').each(function() { //loop through each checkbox

If you want to toggle the checkbox state, you can do like this

var chkd = true;
$('#selectAll').click(function(event) {
    $(":checkbox").prop("checked", chkd);
    chkd = !chkd;
});
