如何在JavaScript中从ASCII字符生成随机字符串

function generateRandomString(length) {
  let result = '';
  const characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
  const charactersLength = characters.length;
  
  for (let i = 0; i < length; i++) {
    const randomIndex = Math.floor(Math.random() * charactersLength);
    const randomChar = characters.charAt(randomIndex);
    result += randomChar;
  }
  
  return result;
}

const randomString = generateRandomString(10);
console.log(randomString);

function generateRandomString(length) {
  let result = '';
  const characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
  const charactersLength = characters.length;
  const randomValues = new Uint8Array(length);
  
  window.crypto.getRandomValues(randomValues);
  
  for (let i = 0; i < length; i++) {
    const randomIndex = randomValues[i] % charactersLength;
    const randomChar = characters.charAt(randomIndex);
    result += randomChar;
  }
  
  return result;
}

const randomString = generateRandomString(10);
console.log(randomString);
