在政府医疗机构工作的乐趣之一是必须处理所有围绕PHI(受保护的健康信息)的偏执。不要误解我的意思,我支持尽一切可能保护人们的个人信息(健康状况、财务状况、上网习惯等),但有时人们会有点太神经质了。
举个例子:我们的一位州客户最近发现浏览器提供了保存密码的方便功能。我们都知道它已经存在了一段时间,完全是可选的,由最终用户决定是否使用它是一个明智的决定。然而,目前有一点骚动,我们被要求找到一种方法来禁用我们网站的功能。
问:网站有没有办法告诉浏览器不要提供记住密码的功能?我从事网络开发已经很长时间了,但我不知道我以前遇到过这种情况。
任何帮助都是感激的。
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">

面对同样的HIPAA问题,我找到了一个相对简单的解决方案,
创建一个隐藏密码字段,字段名为数组。
<input type="password" name="password[]" style="display:none" />
实际密码字段使用相同的数组。
/> . <input type="password" name="password[]
浏览器(Chrome)可能会提示你“保存密码”,但无论用户是否选择保存,下次登录时,密码将自动填充隐藏的密码字段,数组中的零槽,使第一个槽为空。
我尝试定义数组,例如“password[part2]”,但它仍然记得。我认为如果它是一个无索引数组,它就会丢弃它因为它别无选择,只能把它放在第一个位置。
然后使用你选择的编程语言访问数组,比如PHP,
echo $_POST['password'][1];
解决这个问题最简单的方法是将INPUT字段放在FORM标记之外,并在FORM标记内部添加两个隐藏字段。然后在提交事件侦听器中,在表单数据提交到服务器之前,将值从可见输入复制到不可见输入。
下面是一个例子(你不能在这里运行它,因为表单动作没有设置为一个真正的登录脚本):
<!doctype html>
<html>
<head>
<title>Login & Save password test</title>
<meta charset="utf-8">
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
</head>
<body>
<!-- the following fields will show on page, but are not part of the form -->
<input class="username" type="text" placeholder="Username" />
<input class="password" type="password" placeholder="Password" />
<form id="loginForm" action="login.aspx" method="post">
<!-- thw following two fields are part of the form, but are not visible -->
<input name="username" id="username" type="hidden" />
<input name="password" id="password" type="hidden" />
<!-- standard submit button -->
<button type="submit">Login</button>
</form>
<script>
// attache a event listener which will get called just before the form data is sent to server
$('form').submit(function(ev) {
console.log('xxx');
// read the value from the visible INPUT and save it to invisible one
// ... so that it gets sent to the server
$('#username').val($('.username').val());
$('#password').val($('.password').val());
});
</script>
</body>
</html>
因为autocomplete="off"对密码字段不起作用,所以必须依赖javascript。这里有一个简单的解决方案,基于这里找到的答案。
添加属性data-password-autocomplete="off"到你的密码字段:
<input type="password" data-password-autocomplete="off">
包括以下JS:
$(function(){
$('[data-password-autocomplete="off"]').each(function() {
$(this).prop('type', 'text');
$('<input type="password"/>').hide().insertBefore(this);
$(this).focus(function() {
$(this).prop('type', 'password');
});
});
});
这个解决方案适用于Chrome和FF。
