Node浏览器，JavaScript中字符串校验工具库validator。js

　　介绍
　　validator.js是一个Github上专门针对字符串校验所建立的一个工具库，validator.js包含了大量实用的字符串校验和清洗方法，并且支持在Node环境和浏览器环境使用，非常实用。
　　Github
　　https://github.com/validatorjs/validator.js安装实用
　　包管理方式安装npm install validator //或者 yarn add validator
　　可以在各种开发场景下使用不在es6环境下的模块化var validator = require(＂validator＂);  validator.isEmail(＂foo@bar.com＂); //=> truees6的模块化
　　可以一次性全部导入import validator from ＂validator＂;
　　也可以针对不同方法单独引入，比如我们只需要导入验证邮箱的方法import isEmail from ＂validator/lib/isEmail＂;
　　或者Tree-shakeable ES imports导入import isEmail from ＂validator/es/lib/isEmail＂;浏览器直接使用 方法列表
　　方法非常丰富，可以根据需要进行使用，建议先看一下Github上中每个方法的含义和使用方式。import toDate from ＂./lib/toDate＂; import toFloat from ＂./lib/toFloat＂; import toInt from ＂./lib/toInt＂; import toBoolean from ＂./lib/toBoolean＂; import equals from ＂./lib/equals＂; import contains from ＂./lib/contains＂; import matches from ＂./lib/matches＂;  import isEmail from ＂./lib/isEmail＂; import isURL from ＂./lib/isURL＂; import isMACAddress from ＂./lib/isMACAddress＂; import isIP from ＂./lib/isIP＂; import isIPRange from ＂./lib/isIPRange＂; import isFQDN from ＂./lib/isFQDN＂; import isDate from ＂./lib/isDate＂;  import isBoolean from ＂./lib/isBoolean＂; import isLocale from ＂./lib/isLocale＂;  import isAlpha, { locales as isAlphaLocales } from ＂./lib/isAlpha＂; import isAlphanumeric, { locales as isAlphanumericLocales } from ＂./lib/isAlphanumeric＂; import isNumeric from ＂./lib/isNumeric＂; import isPassportNumber from ＂./lib/isPassportNumber＂; import isPort from ＂./lib/isPort＂; import isLowercase from ＂./lib/isLowercase＂; import isUppercase from ＂./lib/isUppercase＂;  import isIMEI from ＂./lib/isIMEI＂;  import isAscii from ＂./lib/isAscii＂; import isFullWidth from ＂./lib/isFullWidth＂; import isHalfWidth from ＂./lib/isHalfWidth＂; import isVariableWidth from ＂./lib/isVariableWidth＂; import isMultibyte from ＂./lib/isMultibyte＂; import isSemVer from ＂./lib/isSemVer＂; import isSurrogatePair from ＂./lib/isSurrogatePair＂;  import isInt from ＂./lib/isInt＂; import isFloat, { locales as isFloatLocales } from ＂./lib/isFloat＂; import isDecimal from ＂./lib/isDecimal＂; import isHexadecimal from ＂./lib/isHexadecimal＂; import isOctal from ＂./lib/isOctal＂; import isDivisibleBy from ＂./lib/isDivisibleBy＂;  import isHexColor from ＂./lib/isHexColor＂; import isRgbColor from ＂./lib/isRgbColor＂; import isHSL from ＂./lib/isHSL＂;  import isISRC from ＂./lib/isISRC＂;  import isIBAN, { locales as ibanLocales } from ＂./lib/isIBAN＂; import isBIC from ＂./lib/isBIC＂;  import isMD5 from ＂./lib/isMD5＂; import isHash from ＂./lib/isHash＂; import isJWT from ＂./lib/isJWT＂;  import isJSON from ＂./lib/isJSON＂; import isEmpty from ＂./lib/isEmpty＂;  import isLength from ＂./lib/isLength＂; import isByteLength from ＂./lib/isByteLength＂;  import isUUID from ＂./lib/isUUID＂; import isMongoId from ＂./lib/isMongoId＂;  import isAfter from ＂./lib/isAfter＂; import isBefore from ＂./lib/isBefore＂;  import isIn from ＂./lib/isIn＂;  import isCreditCard from ＂./lib/isCreditCard＂; import isIdentityCard from ＂./lib/isIdentityCard＂;  import isEAN from ＂./lib/isEAN＂; import isISIN from ＂./lib/isISIN＂; import isISBN from ＂./lib/isISBN＂; import isISSN from ＂./lib/isISSN＂; import isTaxID from ＂./lib/isTaxID＂;  import isMobilePhone, { locales as isMobilePhoneLocales } from ＂./lib/isMobilePhone＂;  import isEthereumAddress from ＂./lib/isEthereumAddress＂;  import isCurrency from ＂./lib/isCurrency＂;  import isBtcAddress from ＂./lib/isBtcAddress＂;  import isISO8601 from ＂./lib/isISO8601＂; import isRFC3339 from ＂./lib/isRFC3339＂; import isISO31661Alpha2 from ＂./lib/isISO31661Alpha2＂; import isISO31661Alpha3 from ＂./lib/isISO31661Alpha3＂; import isISO4217 from ＂./lib/isISO4217＂;  import isBase32 from ＂./lib/isBase32＂; import isBase58 from ＂./lib/isBase58＂; import isBase64 from ＂./lib/isBase64＂; import isDataURI from ＂./lib/isDataURI＂; import isMagnetURI from ＂./lib/isMagnetURI＂;  import isMimeType from ＂./lib/isMimeType＂;  import isLatLong from ＂./lib/isLatLong＂; import isPostalCode, { locales as isPostalCodeLocales } from ＂./lib/isPostalCode＂;  import ltrim from ＂./lib/ltrim＂; import rtrim from ＂./lib/rtrim＂; import trim from ＂./lib/trim＂; import escape from ＂./lib/escape＂; import unescape from ＂./lib/unescape＂; import stripLow from ＂./lib/stripLow＂; import whitelist from ＂./lib/whitelist＂; import blacklist from ＂./lib/blacklist＂; import isWhitelisted from ＂./lib/isWhitelisted＂;  import normalizeEmail from ＂./lib/normalizeEmail＂;  import isSlug from ＂./lib/isSlug＂; import isLicensePlate from ＂./lib/isLicensePlate＂; import isStrongPassword from ＂./lib/isStrongPassword＂;  import isVAT from ＂./lib/isVAT＂;总结
　　validator.js是一个非常值得学习的工具库，不仅是使用它，也可以用它来学习一些JavaScript的基础知识，学习其中各类方法的写法，也可以巩固JavaScript的基础知识！
