过度使用

XMLHttpRequest

@BradyEdgar，我看不出这会有什么好处。添加一个简单包装本机行为的库不会让OP了解AJAX操作是如何工作的。谢谢您的帮助。在添加它并实际调用loadFile（）之后；为了做到这一点，它在我的输出中加入了“undefined”。似乎我不能使用loadFile（）；将该值传递回generate（）函数，并将该值赋给holdPass，它在生成时携带密码。所以这是好消息/坏消息。再次感谢您的帮助！

//Main generate password function
function generatePassword(){
    var x = document.getElementById("passOutput");
    var p = document.getElementById("testP");
    x.value = generate();

    checkMaxChars();
    p.innerText = x.value;
}
