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.

alert("Please Enter Your Password!");
