有.isSpecialCharacter吗？确定是否输入了特殊字符，如(!@#$)？

function hasSpecialCharacter(str) {
  var regex = /[!@#$]/;
  return regex.test(str);
}

var input = "Hello@World";
console.log(hasSpecialCharacter(input)); // true

import java.util.regex.Pattern;
import java.util.regex.Matcher;

public class SpecialCharacterChecker {
  public static boolean hasSpecialCharacter(String str) {
    Pattern pattern = Pattern.compile("[!@#$]");
    Matcher matcher = pattern.matcher(str);
    return matcher.find();
  }

  public static void main(String[] args) {
    String input = "Hello@World";
    System.out.println(hasSpecialCharacter(input)); // true
  }
}

import unittest

def has_special_character(string):
    special_characters = ['!', '@', '#', '$']
    return any(char in special_characters for char in string)

class SpecialCharacterTestCase(unittest.TestCase):
    def test_has_special_character(self):
        self.assertTrue(has_special_character("Hello@World"))

if __name__ == '__main__':
    unittest.main()

#!/bin/bash

input="Hello@World"

if [[ $input =~ [!@#$] ]]; then
  echo "Input contains special characters"
else
  echo "Input does not contain special characters"
