mobiscroll控制选择时间范围

<script type="text/javascript">
    var ctx = '${ctx}';
     $(function () {
            //var currYear = (new Date()).getFullYear();    
            //var currMonth = (new Date()).getMonth();
            var date = new Date();
            var opt={};
            opt.date = {preset : 'date'};
            //opt.datetime = { preset : 'datetime', minDate: new Date(2012,3,10,9,22), maxDate: new Date(2014,7,30,15,44), stepMinute: 5  };
            opt.datetime = {preset : 'datetime'};
            opt.time = {preset : 'time'};
            opt.default = {
                theme: 'android-ics light', //皮肤样式
                display: 'modal', //显示方式 
                dateFormat:'yyyy-mm',
                dateOrder:'yyyymm',
                mode: 'scroller', //日期选择模式
                lang:'zh',
                //startYear:currYear - 20, //开始年份
                //endYear:currYear,  //结束年份
                minDate: new Date(date.getFullYear(),date.getMonth()-6),
                maxDate:new Date(date.getFullYear(),date.getMonth()+6),
                onCancel:function(){//点击取消按钮
                   $('#appDate').val("");//清空时间
                },
                onSelect:function(){//点击确定按钮
                 search();
                },
            };

            var time = $.extend(opt['date'], opt['default']);
            $("#appDate").val('').scroller('destroy').scroller($.extend(opt['date'], opt['default']));
   });
