将年+1即可,代码如下:
var now = new Date()now.setFullYear(now.getFullYear()+1)
alert(now)
给你趴一个看看,先把时间戳转为时间,然后+1年,然后在转为时间戳(function($) { $.extend({ myTime: { /** * 当前时间戳 * @return <int> unix时间戳(秒)*/ CurTime: function(){ return Date.parse(new Date())/1000 }, /*** 日期 转换为 Unix时间戳 * @param <string>2014-01-01 20:20:20 日期格式* @return <int> unix时间戳(秒)*/ DateToUnix: function(string) { var f = string.split(' ', 2) var d = (f[0] ? f[0] : '').split('-', 3) var t = (f[1] ? f[1] : '').split(':', 3) return (new Date( parseInt(d[0], 10) || null, (parseInt(d[1], 10) || 1) - 1, parseInt(d[2], 10) || null, parseInt(t[0], 10) || null, parseInt(t[1], 10) || null, parseInt(t[2], 10) || null )).getTime() / 1000 }, /*** 时间戳转换日期* @param <int>unixTime待时间戳(秒)* @param <bool>isFull返回完整时间(Y-m-d 或者 Y-m-d H:i:s)* @param <int> timeZone 时区*/ UnixToDate: function(unixTime, isFull, timeZone) { if (typeof (timeZone) == 'number') { unixTime = parseInt(unixTime) + parseInt(timeZone) * 60 * 60 } var time = new Date(unixTime * 1000) var ymdhis = "" ymdhis += time.getUTCFullYear() + "-" ymdhis += (time.getUTCMonth()+1) + "-" ymdhis += time.getUTCDate() if (isFull === true) { ymdhis += " " + time.getUTCHours() + ":" ymdhis += time.getUTCMinutes() + ":" ymdhis += time.getUTCSeconds() } return ymdhis } } }) })(jQuery) 调用边的<script>document.write($.myTime.DateToUnix('2016-04-12 10:49:59')+'<br>')document.write($.myTime.UnixToDate(1460429399))</script>function DateAdd(interval,number,date){
