操作cookie
（1）设置cookie
export const setCookie = (key, value, expire) => { const d = new Date(); d.setDate(d.getDate() + expire); document.cookie = `${key}=${value};expires=${d.toUTCString()}` };
（2）读取cookie
export const getCookie = (key) => { const cookieStr = unescape(document.cookie); const arr = cookieStr.split('; '); let cookieValue = ''; for (let i = 0; i < arr.length; i++) { const temp = arr[i].split('='); if (temp[0] === key) { cookieValue = temp[1]; break } } return cookieValue };
（3）删除cookie
export const delCookie = (key) => { document.cookie = `${encodeURIComponent(key)}=;expires=${new Date()}` };
格式校验
（1）校验身份证号码
export const checkCardNo = (value) => { let reg = /(^\d{15}$)|(^\d{18}$)|(^\d{17}(\d|X|x)$)/; return reg.test(value); };
（2）校验是否包含中文
export const haveCNChars => (value) => { return /[\u4e00-\u9fa5]/.test(value); }
（3）校验是否为中国大陆的邮政编码
export const isPostCode = (value) => { return /^[1-9][0-9]{5}$/.test(value.toString()); }
（4）校验是否为IPv6地址
export const isIPv6 = (str) => { return Boolean(str.match(/:/g)?str.match(/:/g).length<=7:false && /::/.test(str)?/^([\da-f]{1,4}(:|::)){1,6}[\da-f]{1,4}$/i.test(str):/^([\da-f]{1,4}:){7}[\da-f]{1,4}$/i.test(str)); }
（5）校验是否为邮箱地址
export const isEmail = (value) { return /^[a-zA-Z0-9_-]+@[a-zA-Z0-9_-]+(\.[a-zA-Z0-9_-]+)+$/.test(value); }
（6）校验是否为中国大陆手机号
export const isTel = (value) => { return /^1[3,4,5,6,7,8,9][0-9]{9}$/.test(value.toString()); }
（7）校验是否包含emoji表情
export const isEmojiCharacter = (value) => { value = String(value); for (let i = 0; i < value.length; i++) { const hs = value.charCodeAt(i); if (0xd800 <= hs && hs <= 0xdbff) { if (value.length > 1) { const ls = value.charCodeAt(i + 1); const uc = ((hs - 0xd800) * 0x400) + (ls - 0xdc00) + 0x10000; if (0x1d000 <= uc && uc <= 0x1f77f) { return true; } } } else if (value.length > 1) { const ls = value.charCodeAt(i + 1); if (ls == 0x20e3) { return true; } } else { if (0x2100 <= hs && hs <= 0x27ff) { return true; } else if (0x2B05 <= hs && hs <= 0x2b07) { return true; } else if (0x2934 <= hs && hs <= 0x2935) { return true; } else if (0x3297 <= hs && hs <= 0x3299) { return true; } else if (hs == 0xa9 || hs == 0xae || hs == 0x303d || hs == 0x3030 || hs == 0x2b55 || hs == 0x2b1c || hs == 0x2b1b || hs == 0x2b50) { return true; } } } return false; }
操作URL
（1）获取URL参数列表
export const GetRequest = () => { let url = location.search; const paramsStr = /.+\?(.+)$/.exec(url)[1]; // 将 ? 后面的字符串取出来 const paramsArr = paramsStr.split('&'); // 将字符串以 & 分割后存到数组中 let paramsObj = {}; // 将 params 存到对象中 paramsArr.forEach(param => { if (/=/.test(param)) { // 处理有 value 的参数 let [key, val] = param.split('='); // 分割 key 和 value val = decodeURIComponent(val); // 解码 val = /^\d+$/.test(val) ? parseFloat(val) : val; // 判断是否转为数字 if (paramsObj.hasOwnProperty(key)) { // 如果对象有 key，则添加一个值 paramsObj[key] = [].concat(paramsObj[key], val); } else { // 如果对象没有这个 key，创建 key 并设置值 paramsObj[key] = val; } } else { // 处理没有 value 的参数 paramsObj[param] = true; } }) return paramsObj; };
（2）检测URL是否有效
export const getUrlState = (URL) => { let xmlhttp = new ActiveXObject("microsoft.xmlhttp"); xmlhttp.Open("GET", URL, false); try { xmlhttp.Send(); } catch (e) { } finally { let result = xmlhttp.responseText; if (result) { if (xmlhttp.Status == 200) { return true; } else { return false; } } else { return false; } } }
（3）键值对拼接成URL参数
export const params2Url = (obj) => { let params = [] for (let key in obj) { params.push(`${key}=${obj[key]}`); } return encodeURIComponent(params.join('&')) }
（4）修改URL中的参数
export const replaceParamVal => (paramName, replaceWith) { const oUrl = location.href.toString(); const re = eval('/('+ paramName+'=)([^&]*)/gi'); location.href = oUrl.replace(re,paramName+'='+replaceWith); return location.href; }
（5）删除URL中指定参数
export const funcUrlDel = (name) => { const baseUrl = location.origin + location.pathname + "?"; const query = location.search.substr(1); if (query.indexOf(name) > -1) { const obj = {}; const arr = query.split("&"); for (let i = 0; i < arr.length; i++) { arr[i] = arr[i].split("="); obj[arr[i][0]] = arr[i][1]; } delete obj[name]; return baseUrl + JSON.stringify(obj).replace(/[\"\{\}]/g,"").replace(/\:/g,"=").replace(/\,/g,"&"); } }
设备判断
（1）判断是移动还是PC设备
export const isMobile = () => { if ((navigator.userAgent.match(/(iPhone|iPod|Android|ios|iOS|iPad|Backerry|WebOS|Symbian|Windows Phone|Phone)/i))) { return 'mobile'; } return 'desktop'; }
（2）判断是否是苹果还是安卓移动设备
export const isAppleMobileDevice = () => { let reg = /iphone|ipod|ipad|Macintosh/i; return reg.test(navigator.userAgent.toLowerCase()); }
（3）判断是否是安卓移动设备
export const isAndroidMobileDevice = () => { return /android/i.test(navigator.userAgent.toLowerCase()); }
（4）判断是Windows还是Mac系统
export const osType = () => { const agent = navigator.userAgent.toLowerCase(); const isMac = /macintosh|mac os x/i.test(navigator.userAgent); const isWindows = agent.indexOf("win64") >= 0 || agent.indexOf("wow64") >= 0 || agent.indexOf("win32") >= 0 || agent.indexOf("wow32") >= 0; if (isWindows) { return "windows"; } if(isMac){ return "mac"; } }
（5）判断是否是微信/QQ内置浏览器
export const broswer = () => { const ua = navigator.userAgent.toLowerCase(); if (ua.match(/MicroMessenger/i) == "micromessenger") { return "weixin"; } else if (ua.match(/QQ/i) == "qq") { return "QQ"; } return false; }
（6）浏览器型号和版本
export const getExplorerInfo = () => { let t = navigator.userAgent.toLowerCase(); return 0 <= t.indexOf("msie") ? { //ie < 11 type: "IE", version: Number(t.match(/msie ([\d]+)/)[1]) } : !!t.match(/trident\/.+?rv:(([\d.]+))/) ? { // ie 11 type: "IE", version: 11 } : 0 <= t.indexOf("edge") ? { type: "Edge", version: Number(t.match(/edge\/([\d]+)/)[1]) } : 0 <= t.indexOf("firefox") ? { type: "Firefox", version: Number(t.match(/firefox\/([\d]+)/)[1]) } : 0 <= t.indexOf("chrome") ? { type: "Chrome", version: Number(t.match(/chrome\/([\d]+)/)[1]) } : 0 <= t.indexOf("opera") ? { type: "Opera", version: Number(t.match(/opera.([\d]+)/)[1]) } : 0 <= t.indexOf("Safari") ? { type: "Safari", version: Number(t.match(/version\/([\d]+)/)[1]) } : { type: t, version: -1 } }
