JS添加天数

//给时间添加天 function AddDay(strInterval, Number, dtTmp) { switch (strInterval) { case 's': return new Date(Date.parse(dtTmp) + (1000 * Number)); case 'n': return new Date(Date.parse(dtTmp) + (60000 * Number)); case 'h': return new Date(Date.parse(dtTmp) + (3600000 * Number)); case 'd': return new Date(Date.parse(dtTmp) + (86400000 * Number)); case 'w': return new Date(Date.parse(dtTmp) + ((86400000 * 7) * Number)); case 'q': return new Date(dtTmp.getFullYear(), (dtTmp.getMonth()) + Number * 3, dtTmp.getDate()); case 'm': return new Date(dtTmp.getFullYear(), (dtTmp.getMonth()) + Number, dtTmp.getDate()); case 'y': return new Date((dtTmp.getFullYear() + Number), dtTmp.getMonth(), dtTmp.getDate()); } }使用如下：AddDay（'d',2,new date()）这个是将时间向后移两天
