一些js方法
生成uuid
exportfunction guid() {
return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function (c) {
var r = Math.random() * 16 | 0,
v = c == 'x' ? r : (r & 0x3 | 0x8);
return v.toString(16);
});
}function UUID (){
var s = [];
var hexDigits = "0123456789abcdef";
for (var i = 0;
i < 36;
i++) {
s[i] = hexDigits.substr(Math.floor(Math.random() * 0x10), 1);
}
s[14] = "4";
// bits 12-15 of the time_hi_and_version field to 0010
s[19] = hexDigits.substr((s[19] & 0x3) | 0x8, 1);
// bits 6-7 of the clock_seq_hi_and_reserved to 01
s[8] = s[13] = s[18] = s[23] = "-";
var uuid = s.join("");
return uuid;
}
隐藏手机号
filterTel(tel) {
if (tel && tel.length == 11) {
let phone = tel;
let myphone = phone.substr(3, 4);
phone = phone.replace(myphone, "****");
return phone;
}
return tel;
}
身份证隐藏年月日
function formatidcard(idcard) {
// 15位身份证举例:130503 670401 001的含义;
13为河北,05为邢台,03为桥西区,出 生日期为1967年4月1日,顺序号为001。
if(idcard.length == 15){
return idcard.replace(/(\d{6})\d{6}(\d{3})/, "$1******$2");
} else {
return idcard.replace(/(\d{5})\d{6}(\d{6})/, "$1******$2");
}
}
判断是否是微信
function isWeixin() {
var ua = navigator.userAgent.toLowerCase();
if(ua.match(/MicroMessenger/i)=="micromessenger") {
return true;
} else {
return false;
}
}
移动端浏览器内核判断
function browserVersions(){
var u = navigator.userAgent, app = navigator.appVersion;
return {//移动终端浏览器版本信息
trident: u.indexOf('Trident') > -1, //IE内核
presto: u.indexOf('Presto') > -1, //opera内核
webKit: u.indexOf('AppleWebKit') > -1, //苹果、谷歌内核
gecko: u.indexOf('Gecko') > -1 && u.indexOf('KHTML') == -1, //火狐内核
mobile: !!u.match(/AppleWebKit.*Mobile.*/), //是否为移动终端
ios: !!u.match(/\(i[^;
]+;
( U;
)? CPU.+Mac OS X/), //ios终端
android: u.indexOf('Android') > -1 || u.indexOf('Linux') > -1, //android终端或uc浏览器
iPhone: u.indexOf('iPhone') > -1 , //是否为iPhone或者QQHD浏览器
iPad: u.indexOf('iPad') > -1, //是否iPad
webApp: u.indexOf('Safari') == -1 //是否web应该程序,没有头部与底部
};
}
一些日期相关的方法
// 获取年加减
export function nowDate(e) {
let d = new Date();
let m = d.getMonth() + 1;
let date = d.getDate();
m = m > 9 ? m : '0' + m;
date = date > 9 ? date : '0' + date;
if (e) {
return (d.getFullYear() + e) + '/' + m + '/' + date;
} else {
return d.getFullYear() + '/' + m + '/' + date;
}
}
// 日期格式化
export function parseTime(time, cFormat) {
if (arguments.length === 0) {
return null
}
const format = cFormat || '{y}-{m}-{d} {h}:{i}:{s}'
let date
if (typeof time === 'object') {
date = time
} else {
if (typeof time == 'number') {
if(('' + time).length === 10){
time = parseInt(time) * 1000
}
} else if (time.indexOf('-') != -1) {
time = time.replace(/\-/g, '/');
}
date = new Date(time)
}
const formatObj = {
y: date.getFullYear(),
m: date.getMonth() + 1,
d: date.getDate(),
h: date.getHours(),
i: date.getMinutes(),
s: date.getSeconds(),
a: date.getDay()
}
const time_str = format.replace(/{(y|m|d|h|i|s|a)+}/g, (result, key) => {
let value = https://www.it610.com/article/formatObj[key]
if (key ==='a') return ['一', '二', '三', '四', '五', '六', '日'][value - 1]
if (result.length > 0 && value < 10) {
value = 'https://www.it610.com/article/0' + value
}
return value || 0
})
return time_str
}// 获取本周第i天的日期
export function getWeek(i,formate='-') {
var now = new Date();
var firstDay = new Date(now - (now.getDay() - 1) * 86400000);
firstDay.setDate(firstDay.getDate() + i);
let mon = Number(firstDay.getMonth()) + 1;
return firstDay.getFullYear() + formate + mon + formate + firstDay.getDate();
}// 获取当前月的第一天和最后一天
export function getMonthDate(num=0){
let date = new Date();
let currentMon = date.getMonth();
date.setMonth(currentMon+num,1);
let startDate = parseTime(date,'{y}-{m}-{d}');
date.setMonth(currentMon+1+num,0);
let endDate = parseTime(date,'{y}-{m}-{d}');
return {
startDate,
endDate
};
}// 加减天
export function addDay(nowDate,num=0){
let now = nowDate.getTime();
now += num*24*3600*1000;
let date = parseTime(new Date(now),'{y}-{m}-{d}');
return date;
}
