今天收集一些非常有用的正则表达式

• url:

/^(?:(?:https?|ftp)://)?(?:(?(?:10|127)(?:.\d{1,3}){3})(?!(?:169.254|192.168)(?:.\d{1,3}){2})(?!172.(?:1[6-9]|2\d|3[0-1])(?:.\d{1,3}){2})(?:[1-9]\d?|1\d\d|2[01]\d|22[0-3])(?:.(?:1?\d{1,2}|2[0-4]\d|25[0-5])){2}(?:.(?:[1-9]\d?|1\d\d|2[0-4]\d|25[0-4]))|(?:(?:[a-z\u00a1-\uffff0-9]-)[a-z\u00a1-\uffff0-9]+)(?:.(?:[a-z\u00a1-\uffff0-9]-)[a-z\u00a1-\uffff0-9]+)(?:.(?:[a-z\u00a1-\uffff]{2,})))(?::\d{2,5})?(?:/\S)?$/i

2. email:

/^((([a-z]|\d|[!#$%&'*+-/=?^{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_{|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+))|((\x22)((((\x20|\x09)(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(\([\x01-\x09\x0b\x0c\x0d-\x7f]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))))(((\x20|\x09)(\x0d\x0a))?(\x20|\x09)+)?(\x22)))@((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|.||_{|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))).)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|.|_|}|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))$/i

3. 身份证号码

^[1-9]\d{5}[1-9]\d{3}((0\d)|(1[0-2]))(([0|1|2]\d)|3[0-1])\d{3}([0-9]|X)$

* 中国大陆手机号码

/(^(13\d|15[4,\D]|17[13678]|18\d)\d{8}|170[^346,\D]\d{7})$/

* 中国固定电话

/^[0-9]{3,4}-[0-9]{7,8}$/

* 信用卡卡号

/^(?:(4[0-9]{12}(?:[0-9]{3})?)|(5[1-5][0-9]{14})|(6(?:011|5[0-9]{2})[0-9]{12})|(3[47][0-9]{13})|(3(?:0[0-5]|[68][0-9])[0-9]{11})|((?:2131|1800|35[0-9]{3})[0-9]{11}))$/

* 中文

/^[\u4e00-\u9fa5]+$/

* 合法的小数

/^[-+]?[0-9]\d*(.\d+)?$/

* 校验金额
