Front-end regular expression

Note 1. The following verification rules are summarized in the company project. You need to modify the rules if some rules are not suitable for you. 2. These rules are written by myself and my colleagues before, and may not be the latest. Welcome to submit them.

Commonly used class

The user name

// User name is regular, with 4 to 16 characters (letters, digits, underscores, minus signs)
var uPattern = / ^ [a - zA - Z0 - _ - 9] $/ dec {4};
// Print true for example: xiaohua_qq
console.log(uPattern.test("caibaojian"));

Password strength

// The password strength is regular and contains at least six characters, including at least one uppercase letter, one lowercase letter, one digit, and one special character
var pPattern = / ^. * (? (=. {6})? =.*\d)(? =.*[A-Z])(? =.*[a-z])(? =. * [! @ # $% ^ & *?] ). * $/;
// Print true, for example, Kd@curry666
console.log(pPattern.test("Kd@curry666"));

// Weak password (less than 6 characters in length, including letters, digits, and special characters)
var pPattern1 = / (? . = {6}). * $/;
/ / output true
console.log(pPattern1.test('asdf'))

// Medium strength password (the password must be 7 or more characters, including two letters and digits, and special characters are optional)
var pPattern2 = / ^ (? = {7}) (((? =.*[A-Z])(? =.*[a-z]))|((? =.*[A-Z])(? =. * [0-9]) | ((? =.*[a-z])(? =. * [0-9]))). * $/;
/ / output true
console.log(pPattern2.test('adb123adg'))

// Strong password (longer than 8 characters, must contain uppercase letters, lowercase letters, digits, special characters) (not verified yet)
var pPattern3 = / ^ (? 1 = {8}) (? =.*[A-Z])(? =.*[a-z])(? =. * ([0-9])? =.*\\W).*$/;
