引用文件时使用时间戳，前端解决缓存问题

< script >

var now = new Date();

        var number = now. getYear(). toString() + now. getMonth(). toString() + now. getDate(). toString();

        document. write( '<script type="text/javascript" src="../../js/redpacket/myRedPacketDetails.js?' + number + '"><\/script\>');

< / script >
