我的js (jquery)的解决方案是改变密码输入类型的文本在表单提交。密码可能在一秒钟内可见，所以我还隐藏了在此之前的输入。我宁愿不使用这个登录表单，但它是有用的(连同autocomplete="off")，例如在网站的管理部分。

在提交表单之前，试着把它放到一个控制台中(使用jquery)。

$('form').submit(function(event) {
    $(this).find('input[type=password]').css('visibility', 'hidden').attr('type', 'text');
});

在Chrome 44.0.2403.157(64位)上测试。

我知道的一种方法是在提交表单之前使用(例如)JavaScript从密码字段中复制值。

这样做的主要问题是解决方案与JavaScript绑定在一起。

同样，如果它可以绑定到JavaScript，那么在向服务器发送请求之前，不妨在客户端对密码进行哈希处理。

我一直在做的是autocomplete="off"和使用javascript / jQuery清除密码字段的组合。

jQuery示例:

$(function() { 
    $('#PasswordEdit').attr("autocomplete", "off");
    setTimeout('$("#PasswordEdit").val("");', 50); 
});

通过使用setTimeout()，您可以等待浏览器在清除字段之前完成该字段，否则浏览器将总是在您清除字段后自动完成。

最干净的方法是使用autocomplete="off"标签属性but 当你用Tab切换字段时，Firefox不能正确地遵守它。

唯一可以阻止这种情况的方法是添加一个虚假的隐藏密码字段，它会欺骗浏览器在那里填充密码。

<input type="text" id="username" name="username"/>
<input type="password" id="prevent_autofill" autocomplete="off" style="display:none" tabindex="-1" />
<input type="password" id="password" autocomplete="off" name="password"/>

这是一种丑陋的黑客行为，因为你改变了浏览器的行为，这应该被认为是糟糕的做法。只有在你真的需要的时候才使用它。

注意:这将有效地停止密码自动填充，因为FF将“保存”#prevent_autofill的值(它是空的)，并将尝试填充那里保存的任何密码，因为它总是使用在DOM中分别输入“username”之后找到的第一个type=“password”输入。

Since most of the autocomplete suggestions, including the accepted answer, don't work in today's web browsers (i.e. web browser password managers ignore autocomplete), a more novel solution is to swap between password and text types and make the background color match the text color when the field is a plain text field, which continues to hide the password while being a real password field when the user (or a program like KeePass) is entering a password. Browsers don't ask to save passwords that are stored in plain text fields.

The advantage of this approach is that it allows for progressive enhancement and therefore doesn't require Javascript for a field to function as a normal password field (you could also start with a plain text field instead and apply the same approach but that's not really HIPAA PHI/PII-compliant). Nor does this approach depend on hidden forms/fields which might not necessarily be sent to the server (because they are hidden) and some of those tricks also don't work either in several modern browsers.

        $this.addClass('no-print');

        $this.css('background-color', $this.css('color'));
        $this.attr('type', 'text');
        $this.attr('autocomplete', 'off');

        $this.focus(function() {
            $this.attr('type', 'password');
            $this.css('background-color', $this.attr('data-background-color'));
        });

        $this.blur(function() {
            $this.css('background-color', $this.css('color'));
            $this.attr('type', 'text');
            $this[0].selectionStart = $this[0].selectionEnd;
        });

        $this.on('keydown', function(e) {
            if (e.keyCode == 13)
            {
                $this.css('background-color', $this.css('color'));
                $this.attr('type', 'text');
                $this[0].selectionStart = $this[0].selectionEnd;
            }
        });
    });
}
}(jQuery));

免责声明:虽然这种方法适用于视力正常的人，但屏幕阅读器软件可能存在问题。例如，屏幕阅读器可能会大声读出用户的密码，因为它看到的是纯文本字段。使用上述插件还可能产生其他不可预见的后果。改变内置的web浏览器功能应该通过测试各种各样的条件和边缘情况来进行。

If you do not want to trust the autocomplete flag, you can make sure that the user types in the box using the onchange event. The code below is a simple HTML form. The hidden form element password_edited starts out set to 0. When the value of password is changed, the JavaScript at the top (pw_edited function) changes the value to 1. When the button is pressed, it checks the valueenter code here before submitting the form. That way, even if the browser ignores you and autocompletes the field, the user cannot pass the login page without typing in the password field. Also, make sure to blank the password field when focus is set. Otherwise, you can add a character at the end, then go back and remove it to trick the system. I recommend adding the autocomplete="off" to password in addition, but this example shows how the backup code works.

<html>
  <head>
    <script>
      function pw_edited() {
        document.this_form.password_edited.value = 1;
      }
      function pw_blank() {
        document.this_form.password.value = "";
      }
      function submitf() {
        if(document.this_form.password_edited.value < 1) {
          alert("Please Enter Your Password!");
        }
        else {
         document.this_form.submit();
        }
      }
    </script>
  </head>
  <body>
    <form name="this_form" method="post" action="../../cgi-bin/yourscript.cgi?login">
      <div style="padding-left:25px;">
        <p>
