                        <span class="input-group-addon">至</span>

                var $t = $(this);
                if ($t.attr("name") == "sDate") {
                    $eDate.datepicker("setStartDate", $t.val());
                } else {
                    $sDate.datepicker("setEndDate", $t.val());
                }
