Примеры jQuery RegEx для использования с .match()

This is a reference post for some common RegExp (regular expressions) selectors that can be used with the jQuery.match() function. This is very handy for finding pretty much anything inside your web page text and then doing something neat with it. Also handy for validation on forms.

Learn how to use Regex with these examples:

jQuery RegExp for Numbers

//select integers only
var intRegex = /[0-9 -()+]+$/;
//match any ip address
var ipRegex = 'bd{1,3}.d{1,3}.d{1,3}.d{1,3}b';
//match number in range 0-255
var num0to255Regex = '^([01][0-9][0-9]|2[0-4][0-9]|25[0-5])$';
//match number in range 0-999
var num0to999Regex = '^([0-9]|[1-9][0-9]|[1-9][0-9][0-9])$';
//match ints and floats/decimals
var floatRegex = '[-+]?([0-9]*.[0-9]+|[0-9]+)';
//Match Any number from 1 to 50 inclusive
var number1to50Regex = /(^[1-9]{1}$|^[1-4]{1}[0-9]{1}$|^50$)/gm;

jQuery RegExp for Validation

//match email address
var emailRegex = '^[A-Z0-9._%+-]+@[A-Z0-9.-]+.[A-Z]{2,4}$';
//match credit card numbers
var creditCardRegex = '^(?:4[0-9]{12}(?:[0-9]{3})?|5[1-5][0-9]{14}|6(?:011|5[0-9][0-9])[0-9]{12}|3[47][0-9]{13}|3(?:0[0-5]|[68][0-9])[0-9]{11}|(?:2131|1800|35d{3})d{11})$';
//match username
var usernameRegex = '/^[a-z0-9_-]{3,16}$/';
//match password
var passwordRegex = '/^[a-z0-9_-]{6,18}$/';
//Match 8 to 15 character string with at least one upper case letter, one lower case letter, and one digit (useful for passwords).
var passwordStrengthRegex = /((?=.*d)(?=.*[a-z])(?=.*[A-Z]).{8,15})/gm;
