切换到漩涡后Javascript功能无法正常工作

Question

我一直在按照指南制作一个安全的登录页面（鉴于我是PHP的新手，而我正在努力学习它）;他们点击后会使用javascript作为处理器＆＃34;提交＆＃34;在注册页面和登录页面上。但是，功能似乎被打破了。我已经对它进行了编辑，因此盐被转换为漩涡，而不是sha512。 这是功能（也是指南的链接：http://www.wikihow.com/Create-a-Secure-Login-Script-in-PHP-and-MySQL）

功能：

function formhash(form, password) {
    // Create a new element input, this will be our hashed password field. 
    var p = document.createElement("input");

    // Add the new element to our form. 
    form.appendChild(p);
    p.name = "p";
    p.type = "hidden";
    p.value = whirlpool(password.value);

    // Make sure the plaintext password doesn't get sent. 
    password.value = "";

    // Finally submit the form. 
    form.submit();
}

function regformhash(form, uid, email, password, conf) {
     // Check each field has a value
    if (uid.value == ''         || 
          email.value == ''     || 
          password.value == ''  || 
          conf.value == '') {

        alert('You must provide all the requested details. Please try again');
        return false;
    }

    // Check the username

    re = /^\w+$/; 
    if(!re.test(form.username.value)) { 
        alert("Username must contain only letters, numbers and underscores. Please try again"); 
        form.username.focus();
        return false; 
    }

    // Check that the password is sufficiently long (min 6 chars)
    // The check is duplicated below, but this is included to give more
    // specific guidance to the user
    if (password.value.length < 6) {
        alert('Passwords must be at least 6 characters long.  Please try again');
        form.password.focus();
        return false;
    }

    // At least one number, one lowercase and one uppercase letter 
    // At least six characters 

    var re = /(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).{6,}/; 
    if (!re.test(password.value)) {
        alert('Passwords must contain at least one number, one lowercase and one uppercase letter.  Please try again');
        return false;
    }

    // Check password and confirmation are the same
    if (password.value != conf.value) {
        alert('Your password and confirmation do not match. Please try again');
        form.password.focus();
        return false;
    }

    // Create a new element input, this will be our hashed password field. 
    var p = document.createElement("input");

    // Add the new element to our form. 
    form.appendChild(p);
    p.name = "p";
    p.type = "hidden";
    p.value = whirlpool(password.value);

    // Make sure the plaintext password doesn't get sent. 
    password.value = "";
    conf.value = "";

    // Finally submit the form. 
    form.submit();
    return true;
