export const isPhone = (s) => {    return /^1[3|4|5|6|7|8|9]\d{9}$/.test(s)}

3.座機號碼

export const isPhones = (s) => {
    return /^([0-9]{3,4}-)?[0-9]{7,8}$/.test(s)
}

4.是否url地址

export const isURL = (s) => {    return /^http[s]?:\/\/.*/.test(s)}

5.是否時間

11.嚴格的身份證校驗

export const isCardID = (sId) => {    if (!/(^\d{15}$)|(^\d{17}(\d|X|x)$)/.test(sId)) {        console.log('你輸入的身份證長度或格式錯誤')        return false    }    //身份證城市    var aCity = { 11: "北京", 12: "天津", 13: "河北", 14: "山西", 15: "內(nèi)蒙古", 21: "遼寧", 22: "吉林", 23: "黑龍江", 31: "上海", 32: "江蘇", 33: "浙江", 34: "安徽", 35: "福建", 36: "江西", 37: "山東", 41: "河南", 42: "湖北", 43: "湖南", 44: "廣東", 45: "廣西", 46: "海南", 50: "重慶", 51: "四川", 52: "貴州", 53: "云南", 54: "西藏", 61: "陜西", 62: "甘肅", 63: "青海", 64: "寧夏", 65: "新疆", 71: "臺灣", 81: "香港", 82: "澳門", 91: "國外" };    if (!aCity[parseInt(sId.substr(0, 2))]) {        console.log('你的身份證地區(qū)非法')        return false    }    // 出生日期驗證    var sBirthday = (sId.substr(6, 4) + "-" + Number(sId.substr(10, 2)) + "-" + Number(sId.substr(12, 2))).replace(/-/g, "/"),        d = new Date(sBirthday)    if (sBirthday != (d.getFullYear() + "/" + (d.getMonth() + 1) + "/" + d.getDate())) {        console.log('身份證上的出生日期非法')        return false    }    // 身份證號碼校驗    var sum = 0,        weights = [7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2],        codes = "10X98765432"    for (var i = 0; i < sId.length - 1; i++) {        sum += sId[i] * weights[i];    }    var last = codes[sum % 11]; //計算出來的最后一位身份證號碼    if (sId[sId.length - 1] != last) {        console.log('你輸入的身份證號非法')        return false    }    return true}

12. 檢測密碼強度

export const isPC = () => {    var userAgentInfo = navigator.userAgent;    var Agents = ["Android", "iPhone",        "SymbianOS", "Windows Phone",        "iPad", "iPod"];    var flag = true;    for (var v = 0; v < Agents.length; v++) {        if (userAgentInfo.indexOf(Agents[v]) > 0) {            flag = false;            break;        }    }    return flag;}

數(shù)組處理

1.數(shù)組排序，{type} 1：從小到大 2：從大到小 3：隨機

export const sort = (arr, type = 1) => {    return arr.sort((a, b) => {        switch (type) {            case 1:                return a - b;            case 2:                return b - a;            case 3:                return Math.random() - 0.5;            default:                return arr;        }    })}

2.求兩個集合的交集

export const intersect = (a, b) => {    var _this = this;    a = this.unique(a);    return this.map(a, function (o) {        return _this.contains(b, o) ? o : null;    });}

3.最大值

6.平均值

export const average = (arr) => {    return this.sum(arr) / arr.length}

字符串處理

1.去除空格,type: 1-所有空格 2-前后空格 3-前空格 4-后空格

export const trim = (str, type) => {    type = type || 1    switch (type) {        case 1:            return str.replace(/\s+/g, "");        case 2:            return str.replace(/(^\s*)|(\s*$)/g, "");        case 3:            return str.replace(/(^\s*)/g, "");        case 4:            return str.replace(/(\s*$)/g, "");        default:            return str;    }}

2.字符轉(zhuǎn)換，type: 1:首字母大寫 2：首字母小寫 3：大小寫轉(zhuǎn)換 4：全部大寫 5：全部小寫

export const changeCase = (str, type) => {    type = type || 4    switch (type) {        case 1:            return str.replace(/\b\w+\b/g, function (word) {                return word.substring(0, 1).toUpperCase() + word.substring(1).toLowerCase();            });        case 2:            return str.replace(/\b\w+\b/g, function (word) {                return word.substring(0, 1).toLowerCase() + word.substring(1).toUpperCase();            });        case 3:            return str.split('').map(function (word) {                if (/[a-z]/.test(word)) {                    return word.toUpperCase();                } else {                    return word.toLowerCase()                }            }).join('')        case 4:            return str.toUpperCase();        case 5:            return str.toLowerCase();        default:            return str;    }}

3.在字符串中插入新字符串

export const insertStr = (soure, index, newStr) => {    var str = soure.slice(0, index) + newStr + soure.slice(index);    return str;}

4.將阿拉伯數(shù)字翻譯成中文的大寫數(shù)字

export const numberToChinese = (num) => {    var AA = new Array("零", "一", "二", "三", "四", "五", "六", "七", "八", "九", "十");    var BB = new Array("", "十", "百", "仟", "萬", "億", "點", "");    var a = ("" + num).replace(/(^0*)/g, "").split("."),        k = 0,        re = "";    for (var i = a[0].length - 1; i >= 0; i--) {        switch (k) {            case 0:                re = BB[7] + re;                break;            case 4:                if (!new RegExp("0{4}//d{" + (a[0].length - i - 1) + "}$")                    .test(a[0]))                    re = BB[4] + re;                break;            case 8:                re = BB[5] + re;                BB[7] = BB[5];                k = 0;                break;        }        if (k % 4 == 2 && a[0].charAt(i + 2) != 0 && a[0].charAt(i + 1) == 0)            re = AA[0] + re;        if (a[0].charAt(i) != 0)            re = AA[a[0].charAt(i)] + BB[k % 4] + re;        k++;    }    if (a.length > 1) // 加上小數(shù)部分(如果有小數(shù)部分)    {        re += BB[6];        for (var i = 0; i < a[1].length; i++)            re += AA[a[1].charAt(i)];    }    if (re == '一十')        re = "十";    if (re.match(/^一/) && re.length == 3)        re = re.replace("一", "");    return re;}

5.將數(shù)字轉(zhuǎn)換為大寫金額

export const changeToChinese = (Num) => {    //判斷如果傳遞進來的不是字符的話轉(zhuǎn)換為字符    if (typeof Num == "number") {        Num = new String(Num);    };    Num = Num.replace(/,/g, "") //替換tomoney()中的“,”    Num = Num.replace(/ /g, "") //替換tomoney()中的空格    Num = Num.replace(/￥/g, "") //替換掉可能出現(xiàn)的￥字符    if (isNaN(Num)) { //驗證輸入的字符是否為數(shù)字        //alert("請檢查小寫金額是否正確");        return "";    };    //字符處理完畢后開始轉(zhuǎn)換，采用前后兩部分分別轉(zhuǎn)換    var part = String(Num).split(".");    var newchar = "";    //小數(shù)點前進行轉(zhuǎn)化    for (var i = part[0].length - 1; i >= 0; i--) {        if (part[0].length > 10) {            return "";            //若數(shù)量超過拾億單位，提示        }        var tmpnewchar = ""        var perchar = part[0].charAt(i);        switch (perchar) {            case "0":                tmpnewchar = "零" + tmpnewchar;                break;            case "1":                tmpnewchar = "壹" + tmpnewchar;                break;            case "2":                tmpnewchar = "貳" + tmpnewchar;                break;            case "3":                tmpnewchar = "叁" + tmpnewchar;                break;            case "4":                tmpnewchar = "肆" + tmpnewchar;                break;            case "5":                tmpnewchar = "伍" + tmpnewchar;                break;            case "6":                tmpnewchar = "陸" + tmpnewchar;                break;            case "7":                tmpnewchar = "柒" + tmpnewchar;                break;            case "8":                tmpnewchar = "捌" + tmpnewchar;                break;            case "9":                tmpnewchar = "玖" + tmpnewchar;                break;        }        switch (part[0].length - i - 1) {            case 0:                tmpnewchar = tmpnewchar + "元";                break;            case 1:                if (perchar != 0) tmpnewchar = tmpnewchar + "拾";                break;            case 2:                if (perchar != 0) tmpnewchar = tmpnewchar + "佰";                break;            case 3:                if (perchar != 0) tmpnewchar = tmpnewchar + "仟";                break;            case 4:                tmpnewchar = tmpnewchar + "萬";                break;            case 5:                if (perchar != 0) tmpnewchar = tmpnewchar + "拾";                break;            case 6:                if (perchar != 0) tmpnewchar = tmpnewchar + "佰";                break;            case 7:                if (perchar != 0) tmpnewchar = tmpnewchar + "仟";                break;            case 8:                tmpnewchar = tmpnewchar + "億";                break;            case 9:                tmpnewchar = tmpnewchar + "拾";                break;        }        var newchar = tmpnewchar + newchar;    }    //小數(shù)點之后進行轉(zhuǎn)化    if (Num.indexOf(".") != -1) {        if (part[1].length > 2) {            // alert("小數(shù)點之后只能保留兩位,系統(tǒng)將自動截斷");            part[1] = part[1].substr(0, 2)        }        for (i = 0; i < part[1].length; i++) {            tmpnewchar = ""            perchar = part[1].charAt(i)            switch (perchar) {                case "0":                    tmpnewchar = "零" + tmpnewchar;                    break;                case "1":                    tmpnewchar = "壹" + tmpnewchar;                    break;                case "2":                    tmpnewchar = "貳" + tmpnewchar;                    break;                case "3":                    tmpnewchar = "叁" + tmpnewchar;                    break;                case "4":                    tmpnewchar = "肆" + tmpnewchar;                    break;                case "5":                    tmpnewchar = "伍" + tmpnewchar;                    break;                case "6":                    tmpnewchar = "陸" + tmpnewchar;                    break;                case "7":                    tmpnewchar = "柒" + tmpnewchar;                    break;                case "8":                    tmpnewchar = "捌" + tmpnewchar;                    break;                case "9":                    tmpnewchar = "玖" + tmpnewchar;                    break;            }            if (i == 0) tmpnewchar = tmpnewchar + "角";            if (i == 1) tmpnewchar = tmpnewchar + "分";            newchar = newchar + tmpnewchar;        }    }    //替換所有無用漢字    while (newchar.search("零零") != -1)        newchar = newchar.replace("零零", "零");    newchar = newchar.replace("零億", "億");    newchar = newchar.replace("億萬", "億");    newchar = newchar.replace("零萬", "萬");    newchar = newchar.replace("零元", "元");    newchar = newchar.replace("零角", "");    newchar = newchar.replace("零分", "");    if (newchar.charAt(newchar.length - 1) == "元") {        newchar = newchar + "整"    }    return newchar;}

其他

export const getQueryString = (name) => {    const reg = new RegExp('(^|&)' + name + '=([^&]*)(&|$)', 'i');    const search = window.location.search.split('?')[1] || '';    const r = search.match(reg) || [];    return r[2];}

2.追加url參數(shù)

export const appendQuery = (url, key, value) => {    var options = key;    if (typeof options == 'string') {        options = {};        options[key] = value;    }    options = $.param(options);    if (url.includes('?')) {        url += '&' + options    } else {        url += '?' + options    }    return url;}

3.動態(tài)引入js

export const injectScript = (src) => {    const s = document.createElement('script');    s.type = 'text/javascript';    s.async = true;    s.src = src;    const t = document.getElementsByTagName('script')[0];    t.parentNode.insertBefore(s, t);}

4.根據(jù)url地址下載

export const download = (url) => {    var isChrome = navigator.userAgent.toLowerCase().indexOf('chrome') > -1;    var isSafari = navigator.userAgent.toLowerCase().indexOf('safari') > -1;    if (isChrome || isSafari) {        var link = document.createElement('a');        link.href = url;        if (link.download !== undefined) {            var fileName = url.substring(url.lastIndexOf('/') + 1, url.length);            link.download = fileName;        }        if (document.createEvent) {            var e = document.createEvent('MouseEvents');            e.initEvent('click', true, true);            link.dispatchEvent(e);            return true;        }    }    if (url.indexOf('?') === -1) {        url += '?download';    }    window.open(url, '_self');    return true;}

5. el是否包含某個class

export const hasClass = (el, className) => {    let reg = new RegExp('(^|\\s)' + className + '(\\s|$)')    return reg.test(el.className)}

6. el添加某個class

export const addClass = (el, className) => {    if (hasClass(el, className)) {        return    }    let newClass = el.className.split(' ')    newClass.push(className)    el.className = newClass.join(' ')}

7. el去除某個class

export const removeClass = (el, className) => {    if (!hasClass(el, className)) {        return    }    let reg = new RegExp('(^|\\s)' + className + '(\\s|$)', 'g')    el.className = el.className.replace(reg, ' ')}

8.獲取滾動的坐標

export const getScrollPosition = (el = window) => ({    x: el.pageXOffset !== undefined ? el.pageXOffset : el.scrollLeft,    y: el.pageYOffset !== undefined ? el.pageYOffset : el.scrollTop});

9.滾動到頂部

export const scrollToTop = () => {    const c = document.documentElement.scrollTop || document.body.scrollTop;    if (c > 0) {        window.requestAnimationFrame(scrollToTop);        window.scrollTo(0, c - c / 8);    }}

10. el是否在視口范圍內(nèi)

export const elementIsVisibleInViewport = (el, partiallyVisible = false) => {    const { top, left, bottom, right } = el.getBoundingClientRect();    const { innerHeight, innerWidth } = window;    return partiallyVisible        ? ((top > 0 && top < innerHeight) || (bottom > 0 && bottom < innerHeight)) &&        ((left > 0 && left < innerWidth) || (right > 0 && right < innerWidth))        : top >= 0 && left >= 0 && bottom <= innerHeight && right <= innerWidth;}

11. 洗牌算法隨機

export const shuffle = (arr) => {    var result = [],        random;    while (arr.length > 0) {        random = Math.floor(Math.random() * arr.length);        result.push(arr[random])        arr.splice(random, 1)    }    return result;}

12.劫持粘貼板

export const copyTextToClipboard = (value) => {    var textArea = document.createElement("textarea");    textArea.style.background = 'transparent';    textArea.value = value;    document.body.appendChild(textArea);    textArea.select();    try {        var successful = document.execCommand('copy');    } catch (err) {        console.log('Oops, unable to copy');    }    document.body.removeChild(textArea);}

13.隨機數(shù)范圍

export const random = (min, max) => {    if (arguments.length === 2) {        return Math.floor(min + Math.random() * ((max + 1) - min))    } else {        return null;    }}

14.函數(shù)節(jié)流器

export const debouncer = (fn, time, interval = 200) => {    if (time - (window.debounceTimestamp || 0) > interval) {        fn && fn();        window.debounceTimestamp = time;    }}

15.判斷兩個對象是否鍵值相同

export const isObjectEqual = (a, b) => {    var aProps = Object.getOwnPropertyNames(a);    var bProps = Object.getOwnPropertyNames(b);    if (aProps.length !== bProps.length) {        return false;    }    for (var i = 0; i < aProps.length; i++) {        var propName = aProps[i];        if (a[propName] !== b[propName]) {            return false;        }    }    return true;}

16.16進制顏色轉(zhuǎn)RGBRGBA字符串

export const colorToRGB = (val, opa) => {    var pattern = /^(#?)[a-fA-F0-9]{6}$/; //16進制顏色值校驗規(guī)則    var isOpa = typeof opa == 'number'; //判斷是否有設置不透明度    if (!pattern.test(val)) { //如果值不符合規(guī)則返回空字符        return '';    }    var v = val.replace(/#/, ''); //如果有#號先去除#號    var rgbArr = [];    var rgbStr = '';    for (var i = 0; i < 3; i++) {        var item = v.substring(i * 2, i * 2 + 2);        var num = parseInt(item, 16);        rgbArr.push(num);    }    rgbStr = rgbArr.join();    rgbStr = 'rgb' + (isOpa ? 'a' : '') + '(' + rgbStr + (isOpa ? ',' + opa : '') + ')';    return rgbStr;}
