正则表达式汇总

整理一部分比较常用的正则表达式、后续会持续更新

1、手机号码的校验

const phoneReg = /^[1][3,4,5,6,7,8,9][0-9]{9}$/

const phoneStr1 = '18886233487'
console.log(phoneReg.test(phoneStr1)) // true

const phoneStr2 = '17283017203897'
console.log(phoneReg.test(phoneStr2)) // false

2、身份证的校验

const sfzReg = /^[1-9]\d{5}(18|19|([23]\d))\d{2}((0[1-9])|(10|11|12))(([0-2][1-9])|10|20|30|31)\d{3}[0-9Xx]$/

const sfzStr1 = '415106199801012130'
console.log(sfzReg.test(sfzStr1)) // true

const sfzStr2 = '718381298381212183'
console.log(sfzReg.test(sfzStr2)) // false

3、邮箱的校验

const emailReg = /^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/

const emailStrWY = '[e-mail]' // 163邮箱
const emailStrQQ = '[e-mail]' // qq邮箱
console.log(emailReg.test(emailStrWY)) // true
console.log(emailReg.test(emailStrQQ)) // true

const noEmail = '72873213.com'
console.log(emailReg.test(noEmail)) // false

4、URL的校验

const urlReg = /^((https?|ftp|file):\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})([\/\w \.-]*)*\/?$/

const urlStr1 = 'https://haha.sunshine.com/xxx/xxx'
console.log(urlReg.test(urlStr1)) // true

const urlStr2 = 'sss://haha.sunshine.com/xxx/xxx'
console.log(urlReg.test(urlStr2)) // false

5、IPv4的校验

const ipv4Reg = /^(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$/

const ipv4Str1 = '122.12.56.65'
console.log(ipv4Reg.test(ipv4Str1)) // true

const ipv4Str2 = '122.12.56.655'
console.log(ipv4Reg.test(ipv4Str2)) // false

6、16进制颜色的校验

const color16Reg = /^#?([a-fA-F0-9]{6}|[a-fA-F0-9]{3})$/

const color16Str1 = '#fff'
console.log(color16Reg.test(color16Str1)) // true

const color16Str2 = '#1234567'
console.log(color16Reg.test(color16Str2)) // false

7、日期 YYYY-MM-DD

const dateReg = /^\d{4}(\-)\d{1,2}\1\d{1,2}$/

const dateStr1 = '2021-10-10'
console.log(dateReg.test(dateStr1)) // true

const dateStr2 = '2021-01-01 1'
console.log(dateReg.test(dateStr2)) // false

8、日期 YYYY-MM-DD hh:mm:ss

const dateReg = /^(\d{1,4})(-|\/)(\d{1,2})\2(\d{1,2}) (\d{1,2}):(\d{1,2}):(\d{1,2})$/

const dateStr1 = '2021-10-10 16:16:16'
console.log(dateReg.test(dateStr1)) // true

9、整数的校验

const intReg = /^[-+]?\d*$/

const intNum1 = 12345
console.log(intReg.test(intNum1)) // true

const intNum2 = 12345.1
console.log(intReg.test(intNum2)) // false

10、小数的校验

const floatReg = /^[-\+]?\d+(\.\d+)?$/

const floatNum = 1234.5
console.log(floatReg.test(floatNum)) // true
