补充知识:Vue中根据时间戳计算时间间隔-年龄
实现目标
由于数据库没有直接存储用户的年龄,只有以时间戳为格式的出生日期,所以不得不在前端做一下计算处理。下面就和大家一起来看一下前端JS的实现方法。
功能代码
由于时间戳是包含了具体时间的,所以在转日期后截取年月日部分即可。
再获取当前的时期计算间隔得出用户的年龄。

// 获取用户年龄 this .userAge = this .toAge(timeStamp); console.log( this .userAge); // 根据返回的日期计算间隔 toAge(timeStamp) { let birthDate = this .toDate(timeStamp).substr(0, 4); let newDate = new Date().getFullYear(); return (newDate - parseInt(birthDate)); } // 时间戳转日期 toDate(number) { let n = number; let date = new Date(n); let Y = date.getFullYear() + '/' ; let M = (date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1) : date.getMonth() + 1) + '/' ; let D = date.getDate() < 10 ? '0' + date.getDate() : date.getDate(); return (Y + M + D) } |
内容小结
又是一个小功能的实现,一边记录下自己的代码,一边和大家分享平时代码的点滴,希望能给大家一个参考,也希望大家多多支持服务器之家。
