Js中获取时间戳可用var dayMiliseconds = parseInt(new Date().valueOf());Js的时间戳单位为毫秒(1s = 1000 ms),下面是一个将制定的格式转化成UTC时间的函数. //format the date string from webservice to UTC time; function toUTCtime(dateStr) { //Date(1381243615503+0530),1381243615503,(138124361550
在vue中的使用: import moment = from “moment” Vue.prototype.$moment = moment; 获取时间戳 : var res = this.$moment(时间, 'YYYY-MM-DD HH:mm:ss').valueOf(); 获取格式时间: var res = this.$moment(时间戳).format('YYYY-MM-DD HH:mm:ss’);

1.inner join ,left join 与 right join (from 百度知道) 例表aaid adate1 a12 a23 a3表bbid bdate1 b12 b24 b4 (1)两个表a,b相连接,要取出id相同的字段 select * from a inner join b on a.aid = b.bid 此时的取出的是:1 a1 b12 a2 b2 (2)left join 指:select * from a left jo
