随机字符串生成器

Question

我想问一下随机字符串生成器的挑战。所以，我从没有淀粉出版社出版的儿童书中获得了这个测验。我是新手，对这个挑战非常困惑，有人可以帮助我吗？

随机字符串生成器

＆＃34;制作一个随机字符串生成器。你需要从一开始包含字母表中所有字母的字符串： var alphabet =＆＃34; abcdefghijklmnopqrstuvwxyz＆＃34 ;; 要从此字符串中选择一个随机字母，您可以更新我们用于随机侮辱发生器的代码第3章：Math.floor（Math.random（）* alphabet.length）。这个将在字符串中创建一个随机索引。然后你可以使用用方括号来获取该索引处的字符。要创建随机字符串，请以空字符串开头（var randomString =＆＃34;＆＃34;）。然后，创建一个while循环不断向这个字符串添加新的随机字母因为字符串长度小于6（或您选择的任何长度）。您可以使用+ =运算符向末尾添加新字母的字符串。循环完成后，将其记录到控制台看到你的创作！＆＃34;

Answer 1

好的，这些说明有点内向，这里的顺序正确：

＆＃13;

// You’ll need to start with a string containing all the letters in the alphabet: 

var alphabet = "abcdefghijklmnopqrstuvwxyz"; 

//  To create the random string, start with an empty string

var randomString = "";

// Then, create a while loop that will continually add new random letters to this string, as long as the string length is less than 6 (or any length you choose). 

while (randomString.length < 6) {

  // To pick a random letter from this string, you can update the code we used for the random insult generator in Chapter 3

  var randomIndex = Math.floor(Math.random() * alphabet.length);
  
  // You can then use square brackets to get the character at that index. 

  var randomChar = alphabet[randomIndex];
  
  // You could use the += operator to add a new letter to the end of the string. 

  randomString += randomChar;
  
}
  
//  After the loop has finished, log it to the console to see your creation!

console.log(randomString);
