(1)、当前时间的时间戳
var now = new Date(); console.log(now.getTime()) //当前时间的时间戳 // 将当前日期转换为时间戳，getTime()方法可返回距1970年1月1日之间的毫秒数。 //也可以使用 +now ，该效果等同于now.getTime()(2)、将指定日期转换为时间戳。
var t = "2017-12-08 20:5:30"; // 月、日、时、分、秒如果不满两位数可不带0. var T = new Date(t); // 将指定日期转换为标准日期格式。Fri Dec 08 2017 20:05:30 GMT+0800 (中国标准时间) console.log(T.getTime()) // 将转换后的标准日期转换为时间戳。需求及效果图： 下次追访时间 添加 6小时后，一天后，本周五 三个快捷选项
案例讲解： 如果下次追访时间 为周五周六周日 ，则不显示本周五选项；

选项时间计算讲解：
let zfselidx = e.currentTarget.dataset.index let zfdaytime = new Date(this.data.next_zhuifang_day + ' ' + this.data.zhuifang_time) //日期时间 console.log(zfdaytime.getTime()) console.log(zfdaytime.getTime() / 1000) zfdaytime = parseInt(zfdaytime.getTime() / 1000) //转为时间戳 秒 // console.log(zfdaytime) zfdaytime = zfdaytime + 6 * 3600 zfdaytime = new Date(zfdaytime * 1000) //转为时间戳 // console.log(zfdaytime) this.setData({ next_zhuifang_day: util.formatDate(zfdaytime), zhuifang_time: util.formatTime(zfdaytime), weekday: util.getWeek(util.formatDate(zfdaytime)), })将当前选择的时间 转成时间戳后 再相应的计算 ，之后，再转回时间，对应的赋值便可。
