jQuery常用正则匹配表达式


//整数
"^-?[1-9]\\d*$",

//正整数 
"^[1-9]\\d*$",

//负整数
intege2: "^-[1-9]\\d*$",

//数字
num: "^([+-]?)\\d*\\.?\\d+$",

//正数(正整数 + 0)
num1: "^[1-9]\\d*|0$",

//负数(负整数 + 0)
num2: "^-[1-9]\\d*|0$",

//浮点数
decmal: "^([+-]?)\\d*\\.\\d+$",

//正浮点数
decmal1: "^[1-9]\\d*.\\d*|0.\\d*[1-9]\\d*$",
  

//负浮点数
decmal2: "^-([1-9]\\d*.\\d*|0.\\d*[1-9]\\d*)$",
 

//浮点数
decmal3: "^-?([1-9]\\d*.\\d*|0.\\d*[1-9]\\d*|0?.0+|0)$",
 

//非负浮点数(正浮点数 + 0)
decmal4: "^[1-9]\\d*.\\d*|0.\\d*[1-9]\\d*|0?.0+|0$",
  

//非正浮点数(负浮点数 + 0)
decmal5: "^(-([1-9]\\d*.\\d*|0.\\d*[1-9]\\d*))|0?.0+|0$",
  

//邮件
email: "^\\w+((-\\w+)|(\\.\\w+))*\\@[A-Za-z0-9]+((\\.|-)[A-Za-z0-9]+)*\\.[A-Za-z0-9]+$",

//颜色
color: "^[a-fA-F0-9]{6}$",

//url
url: "^http[s]?:\\/\\/([\\w-]+\\.)+[\\w-]+([\\w-./?%&=]*)?$",

//仅中文
chinese: "^[\\u4E00-\\u9FA5\\uF900-\\uFA2D]+$",

//仅ACSII字符
ascii: "^[\\x00-\\xFF]+$",

//邮编
zipcode: "^\\d{6}$",

//手机
mobile: "^(13|15)[0-9]{9}$",

//ip地址
ip4: "^(25[0-5]|2[0-4]\\d|[0-1]\\d{2}|[1-9]?\\d)\\.(25[0-5]|2[0-4]\\d|[0-1]\\d{2}|[1-9]?\\d)\\.(25[0-5]|2[0-4]\\d|[0-1]\\d{2}|[1-9]?\\d)\\.(25[0-5]|2[0-4]\\d|[0-1]\\d{2}|[1-9]?\\d)$",

//非空
notempty: "^\\S+$",

//图片
picture: "(.*)\\.(jpg|bmp|gif|ico|pcx|jpeg|tif|png|raw|tga)$",

//压缩文件
rar: "(.*)\\.(rar|zip|7zip|tgz)$",

//日期
date: "^\\d{4}(\\-|\\/|\.)\\d{1,2}\\1\\d{1,2}$",

//QQ号码
qq: "^[1-9]*[1-9][0-9]*$",

//电话号码的函数(包括验证国内区号,国际区号,分机号)
tel: "^(([0\\+]\\d{2,3}-)?(0\\d{2,3})-)?(\\d{7,8})(-(\\d{3,}))?$",

//用来用户注册。匹配由数字、26个英文字母或者下划线组成的字符串
username: "^\\w+$",

//字母
letter: "^[A-Za-z]+$",

//大写字母
letter_u: "^[A-Z]+$",

//小写字母
letter_l: "^[a-z]+$",

//身份证
idcard: "^[1-9]([0-9]{14}|[0-9]{17})$"
