How to select multiple items from listbox in jquery using comma separated value?

In general, when we are getting comma separated value from database, we need to split and loop to select multiple items from the ListBox.

var employeeIds = '@ViewBag.EmployeeIds'; // comma separated value
    var array = employeeIds.split(',');
    for (var i = 0; i < array.length; i++) {
        if (array[i].length > 0) {
            $('#EmployeeIds option[value=' + array[i] + ']').attr("selected", true);
        }
    }

Here we are assuming that ViewBag.EmployeeIds have comma separated value, #EmployeeIds is the id of the listbox.
