Node: 将时间戳转换成日期并分组
作者:互联网
// 对时间戳按日期进行分组
let moment = require('moment')
let timestamp_array = [
1645059333000,
1613523333000,
1297904133000,
1298076933000,
1582073733000,
1645318535000,
1647389537000
]
let result = {}
for (let index in timestamp_array) {
let timestamp = timestamp_array[index]
let date = moment(timestamp).format("YYYY-MM-DD");
// let date = moment(timestamp).format("YYYY-MM");
// console.log(date);
let date_split_array = date.split('-')
// console.log(date_split_array);
// 先判断年,之后判断月份
let year = date_split_array[0]
let month = date_split_array[1]
let judge_year = result.hasOwnProperty(year)
if (judge_year == false) {
result[year] = {}
// result[year][date] = data
judge_month(year, month,date)
} else {
// result[year][date] = data
judge_month(year, month,date)
}
}
console.log(result);
function judge_month(year,month,date) {
/*
year: 字典中的年
month:
*/
let judge_month = result[year].hasOwnProperty(month)
if(judge_month == false){
result[year][month] = {}
result[year][month][date] = date
}else{
result[year][month][date] = date
}
}
运行结果如下所示
