1.必须包含大小写数字 8-16位

/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)[a-zA-Z0-9]{8,16}$/复制代码

2.数字千分位展示

function numberWithCommas(x) {  return x.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");}复制代码

3.转义需要转义的

function escapeRegexp(queryToEscape) {  return queryToEscape.replace(/([.?*+^$[\]\\(){}|-])/g, '\\$1')}复制代码

4. 连字符转驼峰 ad-bd-cd to adBdCd

var camelizeRE = /-(\w)/g;var camelize = function (str) {  return str.replace(camelizeRE, function (_, c) {    return c ? c.toUpperCase() : '';  })}复制代码

5.驼峰转连字符

var hyphenateRE = /\B([A-Z])/g;var hyphenate = function (str) {  return str.replace(hyphenateRE, '-$1').toLowerCase()};复制代码

6.转义html

function htmlEscape(text){  return text.replace(/[<>"&]/g, function(match, pos, originalText){    console.log(match, pos, originalText)    switch(match){      case "<": return "<";      case ">":return ">";      case "&":return "&";      case "\"":return """;    }  });}复制代码

7.判断相对 绝对路径

var absolutePath = /^(?:\/|(?:[A-Za-z]:)?[\\|/])/;var relativePath = /^\.?\.\//;function isAbsolute(path$$1) {  return absolutePath.test(path$$1);}function isRelative(path$$1) {  return relativePath.test(path$$1);}复制代码
