[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.

我遇到过类似的问题，输入字段要么取名字，要么取电子邮件。我设置autocomplete=“关闭”，但Chrome仍然强制建议。事实证明，这是因为占位符文本中有“姓名”和“电子邮件”这两个词。

例如

<input type="text" placeholder="name or email" autocomplete="off" />

我通过在占位符中的单词中放入零宽度的空格来解决这个问题。没有更多的Chrome自动完成。

<input type="text" placeholder="nam&#8203;e or emai&#8203;l" autocomplete="off" />

隐藏的输入元素技巧似乎仍然有效(Chrome 43)，以防止自动填充，但要记住的一件事是Chrome将尝试基于占位符标记自动填充。您需要将隐藏输入元素的占位符与您试图禁用的输入的占位符匹配。

在我的情况下，我有一个字段的占位符文本“城市或Zip”，我正在使用谷歌地方自动完成。它似乎试图自动填写，就好像它是一个地址表单的一部分。直到我在隐藏元素上放置了与实际输入相同的占位符，这个技巧才起作用:

<input style="display:none;" type="text" placeholder="City or Zip" />
<input autocomplete="off" type="text" placeholder="City or Zip" />

看起来这是固定的!参见https://codereview.chromium.org/1473733008

目前的解决方案是使用type="search"。谷歌不会对输入的搜索类型应用自动填充。

更新04/04/2016:看起来这是固定的!参见http://codereview.chromium.org/1473733008

在Chrome 48+使用这个解决方案:

Put fake fields before real fields: <form autocomplete="off"> <input name="fake_email" class="visually-hidden" type="text"> <input name="fake_password" class="visually-hidden" type="password"> <input autocomplete="off" name="email" type="text"> <input autocomplete="off" name="password" type="password"> </form> Hide fake fields: .visually-hidden { margin: -1px; padding: 0; width: 1px; height: 1px; overflow: hidden; clip: rect(0 0 0 0); clip: rect(0, 0, 0, 0); position: absolute; } You did it!

同样，这也适用于旧版本。
