直播系统定制，根据日期计算年龄
// 根据日期计算年龄 getAge(strBirthday) { //strBirthday传入格式 2020-04-15 var returnAge; var strBirthdayArr = strBirthday.split('-'); var birthYear = strBirthdayArr[0]; var birthMonth = strBirthdayArr[1]; var birthDay = strBirthdayArr[2]; //获取当前日期 var d = new Date(); var nowYear = d.getFullYear(); var nowMonth = d.getMonth() + 1; var nowDay = d.getDate(); if (nowYear == birthYear) { returnAge = 0; //同年 则为0岁 } else { var ageDiff = nowYear - birthYear; //年之差 if (ageDiff > 0) { if (nowMonth == birthMonth) { var dayDiff = nowDay - birthDay; //日之差 if (dayDiff < 0) { returnAge = ageDiff - 1; } else { returnAge = ageDiff; } } else { var monthDiff = nowMonth - birthMonth; //月之差 if (monthDiff < 0) { returnAge = ageDiff - 1; } else { returnAge = ageDiff; } } } else { returnAge = -1; //返回-1 表示出生日期输入错误 晚于今天 } } return returnAge; //返回周岁年龄 },以上就是直播系统定制，根据日期计算年龄的相关代码， 更多内容欢迎关注之后的文章
