当使用像jQuery UI的自动完成这样的小部件时，请确保它没有将自动完成属性添加/更改为关闭。在使用它时，我发现这是正确的，并且会破坏您为覆盖任何浏览器字段缓存所做的任何工作。确保拥有唯一的name属性，并在小部件初始化后强制使用唯一的自动完成属性。下面是一些关于如何在你的情况下工作的提示。

<?php $autocomplete = 'off_'.time(); ?>
<script>
   $('#email').autocomplete({
      create: function( event, ui ) {
         $(this).attr('autocomplete','<? echo $autocomplete; ?>');
      },
      source: function (request, response) { //your code here },
      focus: function( event, ui ) { //your code here },
      select: function( event, ui ) { //your code here },
   });
</script>
<input type="email" id="email" name="email_<? echo $autocomplete; ?>" autocomplete="<? echo $autocomplete; ?>" />

[2021年适用于Chrome(v88, 89, 90)， Firefox, Brave, Safari] 旧的答案已经写在这里，将适用于试验和错误，但大多数 他们没有链接到任何官方文件或什么Chrome不得不说这一点 的事。

问题中提到的问题是因为Chrome的自动填充功能，这里是Chrome在这个bug链接中的立场- https://bugs.chromium.org/p/chromium/issues/detail?id=468153#c164

简单地说，有两种情况-

[CASE 1]: Your input type is something other than password. In this case, the solution is simple, and has three steps. Add name attribute to input name should not start with a value like email or username, otherwise Chrome still ends up showing the dropdown. For example, name="emailToDelete" shows the dropdown, but name="to-delete-email" doesn't. Same applies for autocomplete attribute. Add autocomplete attribute, and add a value which is meaningful for you, like new-field-name It will look like this, and you won't see the autofill for this input again for the rest of your life - <input type="text/number/something-other-than-password" name="x-field-1" autocomplete="new-field-1" /> [CASE 2]: input type is password Well, in this case, irrespective of your trials, Chrome will show you the dropdown to manage passwords / use an already existing password. Firefox will also do something similar, and same will be the case with all other major browsers. [1] In this case, if you really want to stop the user from seeing the dropdown to manage passwords / see a securely generated password, you will have to play around with JS to switch input type, as mentioned in the other answers of this question.

对任何想要解决这个问题的人来说，我终于明白了。

Chrome只服从的自动完成="off"如果页面是HTML5页面(我使用XHTML)。

我把我的页面转换成HTML5，问题就消失了(捂脸)。

似乎Chrome现在忽略autocomplete="off"，除非它是在<form autocomplete="off">标签。

为了防止自动补全，只需设置一个空白作为输入值:

<input type="text" name="name" value="  ">
