  $(function () {

        function MoveItem(fromId, toId) {
            $("#" + fromId + " option:selected").each(function () {
                $(this).appendTo($("#" + toId + ":not(:has(option[value=" + $(this).val() + "]))"));
            });
            $("#" + fromId + " option:selected").remove();
        }

 
        $("#addUser").click(function () {
            var fromId = "User";
            var toId = "UserSelected";
            MoveItem(fromId, toId);
        });

        $("#removeUser").click(function () {
            var fromId = "UserSelected";
            var toId = "User";
            MoveItem(fromId, toId);
        });

        //双击选项
        $(‘#User‘).dblclick(function () {
            var toId = "UserSelected";
            var fromId = "User";
            MoveItem(fromId, toId);
        });
