Answer 1

Put hdnDepartment in a surrounding div

<div id="departmentCheck">
      <input type="hidden" value="true,true,false,false" id="hdnDepartment" />
</div>

and the jquery should be

$(document).ready(function () {
   var revalue = new Array();

    if ($('#departmentCheck input').val() != "") {

        var str = $('#departmentCheck input').val();
        revalue = str.split(',');
         var counter=0;

         $('#idOfMultiselect option').each(function(k,v){

            try{

               //if catch if there is no index at counter in revalue then default to false
               $(v).attr('checked', revalue[counter]);


             }
             catch{
                $(v).attr('checked',false);

             }

            counter++;

           });


            }
        });
