How to don't allow set only the same characters and only special sign - regex js

I'm looking for some regex pattern to:

  • not allow set the same characters
  • not allow only special signs.

So:

  • 11111111 - not allow
  • 1111811111 - allow
  • rrrrrrrr - not allow
  • rrrrrrrrrr5 - allow
  • 11111111% - allow
  • %$!@$!@@@@ - not allow
  • %%%%%%%%%1 - allow

I found regex which is helpful for recognize that string has only special sign: /^\W*\w.*$/, but I don't know how to join it with condition about not only repeated characters. Thansks for any advices.

You can assert not only the same characters and make sure to match at least a single word character.

^(?!(.)\1+$)[^\w\n]*\w.*$

Explanation

  • ^ Start of string
  • (?!(.)\1+$) Negative lookahead, assert not only the same characters in the string matching at least 2 characters
  • [^\w\n]* Optionally match any character except a word character or newline
  • \w Match at least a single word character
  • .* Optionally match any character
  • $ End of string

Regex demo

const regex = /^(?!(.)\1+$)[^\w\n]*\w.*$/;
[
  "11111111",
  "1111811111",
  "rrrrrrrr",
  "rrrrrrrrrr5",
  "11111111%",
  "%$!@$!@@@@",
  "%%%%%%%%%1",
  "a"
].forEach(s => {
  if (regex.test(s)) {
    console.log(s + " allow")
  } else {
    console.log(s + " not allow")
  }
});


If you don't want to match any spaces in the string, you can match non whitespace chars using \S

^(?!(\S)\1+$)[^\w\s]*\w\S*$
