因为在实操中,后台大多数都是直接给时间戳格式,故这里的传参都为时间戳,(封装方法为ES6,适用于微信小程序,vue 等框架,也适用于正常js)
注:时间戳为10位需*1000,时间戳为13位的话不需乘1000
普通时间戳转化年月日
const timeStamp = dateStamp => { // 转化格式为2019年2月28日,可自己修改
let date = new Date(dateStamp);
let Y = date.getFullYear() + '年';
let M = (date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1) : date.getMonth() + 1) + '月';
let D = date.getDate() + '日';
let tempDate = Y + M + D;
return tempDate;
}
转化为年月日周(大写小写周)
const timeYMDWeek = dateStamp => { // 转化为年月日周--------
let date = new Date(dateStamp); //时间戳为10位需*1000,时间戳为13位的话不需乘1000
let Y = date.getFullYear(); // 年
let M = date.getMonth() + 1; // 月
let D = date.getDate(); // 日
let W = date.getDay(); // 周 0-6(周日到周六)
let Ww = date.getDay(); // 周日到周六
//使用数组更改日期样式;
var dayCycleArray = ["日", "一", "二", "三", "四", "五", "六"];
for (let i = 0; i < 7; i++) {
if (W == i) {
//将dayCycleArray的数赋值到系统星期几里面中去;
Ww = dayCycleArray[i];
}
}
let selfTempDate = [Y, M, D, W, Ww];
return selfTempDate;
}
注意周是从周日开始到周六 (即0-6,0代表周日,6代表周六类推)
时间戳转换今天昨天
const timeSetTodayAndYesterday = dateStamp => { // 转化为今天昨天
// 如果年月日和服务器时间相等 转化 否则02-21
// 1.接收传入时间
let tt = new Date(dateStamp);
let days = parseInt((new Date().getTime() - tt) / 86400000);
// 今天时间
var today = new Date().getDate();
var year = tt.getFullYear();
var mouth = tt.getMonth() + 1 < 10 ? '0' + (tt.getMonth() + 1) : tt.getMonth() + 1;
var day = tt.getDate() < 10 ? '0' + tt.getDate() : tt.getDate();
var time = tt.getHours() < 10 ? "0" + tt.getHours() : tt.getHours();
var min = tt.getMinutes() < 10 ? "0" + tt.getMinutes() : tt.getMinutes();
var result, offset;
offset = Math.abs(today - day);
if (days < 2 && offset < 2) {
if (offset === 0) {
result = "今天";
}
if (offset === 1) {
result = "昨天";
}
// else if (offset === 2) {
// result = "前天" + time + ":" + min;
} else {
result = mouth + "-" + day
}
var todayAndYesterday = [result, time, min];
return todayAndYesterday;
}
判断条件days 可改为不同值来判断天数,还可加至多少分钟前等
判断两时间戳是否相等
const timeIsToday = dateStamp => { // 判断两时间戳是否相等
let dateTime = new Date(dateStamp); //时间戳为10位需*1000,时间戳为13位的话不需乘1000
let Y = dateTime.getFullYear();
let M = dateTime.getMonth();
let D = dateTime.getDate();
// 取当前时间
let today = new Date();
let today_Y = today.getFullYear();
let today_M = today.getMonth();
let today_D = today.getDate();
if (today_Y == Y && today_M == M && today_D == D) {
return true;
}
return false;
}
阿拉伯数字转换为简写汉字
const arabia_To_SimplifiedChinese = (num) => {
for (let i = num.length - 1; i >= 0; i--) {
num = num.replace(",", "") //替换num中的“,”
num = num.replace(" ", "") //替换num中的空格
}
if (isNaN(num)) { //验证输入的字符是否为数字
//alert("请检查小写金额是否正确");
return;
}
var part;
var newchar;
//字符处理完毕后开始转换,采用前后两部分分别转换
part = String(num).split(".");
newchar = "";
//小数点前进行转化
for (let i = part[0].length - 1; i >= 0; i--) {
if (part[0].length > 10) {
//alert("位数过大,无法计算");
return "";
} //若数量超过拾亿单位,提示
var tmpnewchar;
var perchar;
tmpnewchar = ""
perchar = part[0].charAt(i);
switch (perchar) {
case "0":
tmpnewchar = "零" + tmpnewchar;
break;
case "1":
tmpnewchar = "一" + tmpnewchar;
break;
case "2":
tmpnewchar = "二" + tmpnewchar;
break;
case "3":
tmpnewchar = "三" + tmpnewchar;

break;
}
switch (part[0].length - i - 1) {
case 0:
tmpnewchar = tmpnewchar;
break;
case 1:
if (perchar != 0) tmpnewchar = tmpnewchar + "十";
break;
case 2:
if (perchar != 0) tmpnewchar = tmpnewchar + "百";
break;
case 3:
if (perchar != 0) tmpnewchar = tmpnewchar + "千";
break;
case 4:
tmpnewchar = tmpnewchar + "万";
break;
case 5:
if (perchar != 0) tmpnewchar = tmpnewchar + "十";
break;
case 6:
if (perchar != 0) tmpnewchar = tmpnewchar + "百";
break;
case 7:
if (perchar != 0) tmpnewchar = tmpnewchar + "千";
break;
case 8:
tmpnewchar = tmpnewchar + "亿";
break;
case 9:
tmpnewchar = tmpnewchar + "十";
break;
}
newchar = tmpnewchar + newchar;
}
//替换所有无用汉字,直到没有此类无用的数字为止
while (newchar.search("零零") != -1 || newchar.search("零亿") != -1 || newchar.search("亿万") != -1 || newchar.search("零万") != -1) {
newchar = newchar.replace("零亿", "亿");
newchar = newchar.replace("亿万", "亿");
newchar = newchar.replace("零万", "万");
newchar = newchar.replace("零零", "零");
}
//替换以“一十”开头的,为“十”
if (newchar.indexOf("一十") == 0) {
newchar = newchar.substr(1);
}
//替换以“零”结尾的,为“”
if (newchar.lastIndexOf("零") == newchar.length - 1) {
newchar = newchar.substr(0, newchar.length - 1);
}
return newchar;
