我是编码新手，我不知道为什么我的JS没有生成随机密码。 通过提示单击确定，您将看到我遇到的问题。 它似乎只是在//生成器函数中提取我的一个函数。 我将提示编码为非常简单，因为我仍然不太清楚我在做什么。 我只需要它来生成此特定练习的密码。 任何帮助不胜感激！
// Assignment Code
var generateBtn = document.querySelector("#generate");

passwordText.value = password;
}
// Add event listener to generate button

// Prompts that come up after you click generate password
