经过几个月的努力，我发现解决办法比你想象的要简单得多:

用autocomplete="false"代替autocomplete="off";)

就这么简单，它的工作就像一个魅力在谷歌Chrome浏览器以及!

2019年8月更新(评论中来自@JonEdiger)

注意:网上有很多信息说浏览器现在处理autocomplete='false'与autocomplete='off'相同。至少在这一刻，它阻止了这三个浏览器的自动完成。

在表单级别设置它，然后对于你想关闭的输入，设置为一些无效的值，比如'none':

<form autocomplete="off"> 
  <input type="text" id="lastName" autocomplete="none"/> 
  <input type="text" id="firstName" autocomplete="none"/>
</form>

Finally I think I came with a decent solution. Understanding better how the dropdown works with Chrome helped :) Basically, the dropdown will be displayed when you focus the input and when you generate a mouse down event when you are typing an entry which matches with what Chrome has in memory. Keeping that in mind, and that Chrome does it for certain inputs when they have default names like "name", "email", etc. then we just need to remove the name when the dropdown is going to be displayed and add it back after :) I wanted to use a solution which can make it work just by adding the attribute autocomplete off. I thought it made sense. This is the code:

解决方案1

jQuery('body').on('mousedown','[name="name"][autocomplete="off"], [name="email"][autocomplete="off"]',function(e){
    e.stopImmediatePropagation();
    if(typeof this.currentName =="undefined")
        this.currentName=jQuery(this).attr('name');
    jQuery(this).attr('name','');
});

jQuery('body').on('blur','[autocomplete="off"]',function(e){
    e.stopImmediatePropagation();
    jQuery(this).attr('name',this.currentName);
});

解决方案2(我最喜欢的一个)

The solution I described above will remove the name of the input until we remove the focus (blur), in that moment it will put the original name back. But might happen that we are interested on having access to the input through its name attribute while we are typing. Which means that we need to put the name back right after each input. This solution, basically is based on the first solution. In this case, we will add the name on key down, and put it back on keyup. I think this is more neat for compatibility with what the "autocomplete off" behaviour should be. Anyway this is the code:

jQuery('body').on('mousedown keydown','[name="name"][autocomplete="off"], [name="email"][autocomplete="off"]',function(e){
    e.stopImmediatePropagation();
    if(typeof this.currentName =="undefined")
        this.currentName=jQuery(this).attr('name');
    jQuery(this).attr('name','');
});
jQuery('body').on('blur keyup','[autocomplete="off"]',function(e){
    e.stopImmediatePropagation();
    if(typeof this.currentName !="undefined")
        jQuery(this).attr('name',this.currentName);
});

请注意，对于解决方案1和2，我只采用输入名称为“name”和“email”的情况。对于任何其他情况下，这个属性使Chrome生成下拉，你将不得不添加它在选择器的鼠标下拉事件。

解决方案3

这个解决方案要复杂得多。我没有意识到我们试图纠正的行为只是基于那些带有特定名称的输入，如“姓名，电子邮件等”。这种解决方案的方法是在这种情况下，Chrome显示的其他名称，我们不知道一个先验。这将是一个非常通用的解决方案。我不像其他两个那样喜欢，主要是因为当我们按下删除键时，可能会有一个小闪烁。我会在下面解释。

我发现，下拉框出现在第二次点击输入后，而不是第一次点击时，当你第一次聚焦在输入上时。我为所有这些元素绑定了一个“mousedown”事件，其中处理程序基本上检测它是否已经聚焦在输入上，如果它检测到另一个“鼠标向下”，强制一个.blur()，然后是.focus()，防止第二次点击时的下拉。我希望，这是清楚的，以防万一，这是我使用的代码:

jQuery('body').on('mousedown','[autocomplete="off"]',function(e){
    e.stopImmediatePropagation();
    if(jQuery(this).is(':focus')) {
        jQuery(this).blur();
        jQuery(this).focus();
    }
});

In the other hand, in order to prevent the dropdown while you are typing in case it matches with Chrome suggestions... This is a little bit tricky. I just decided to replace the default behaviour of an input while user types. The dropdown evaluates the input on mouse down, so I prevent the default behaviour for alphanumerics, space, etc. The only problem is with Command,Ctrl and delete. For this case I had to bind also an event on mouse up. It allows the default behaviour in the first two cases so you can make copy, and paste, or select all. In the case of the delete, I have to allow the default behaviour, but if after deleting a character the input matches with Chrome suggestions, then again it was showing the dropdown. For this case I had to use the same trick of blur and focus. The only inconvenience I found on this is that since we are cancelling the behaviour on keyup, and chrome tries to show it on keydown, there is a small flicker. Anyway, this is the best I could do. Probably it will require for filtering of characters at one point. I just added the conditions made more sense for now. This is the second part of the code:

jQuery('body').on('keydown','[autocomplete="off"]',function(e){
    e.stopImmediatePropagation();
    var ctrlKey = 17,cmKey = 91;
    var charCode = e.which || e.keyCode;

    if(charCode!=16 && this.commandDown != true && this.ctrlDown != true && ((charCode>47 && charCode<58)||(charCode>64 && charCode<91)||(charCode>96 && charCode<123)||charCode==0 || charCode==32)){ 
        e.preventDefault();
        var charStr = String.fromCharCode(charCode);
        if(!e.shiftKey)
            charStr = charStr.toLowerCase(charStr);
        $(this).val($(this).val() + charStr);
    }else{
        if (charCode == cmKey) this.commandDown = true;
        if (charCode == ctrlKey) this.ctrlDown = true;
    }
});
jQuery('body').on('keyup','[autocomplete="off"]',function(e){
    e.stopImmediatePropagation();
    var allowed=[8];//Delete
    var ctrlKey = 17,cmKey = 91;
    var charCode = e.which || e.keyCode;

    if (charCode == cmKey) {this.commandDown = false};
    if (charCode == ctrlKey) {this.ctrlDown = false};
    if(allowed.indexOf(charCode)>=0 || (this.commandDown!=false && this.ctrlDown!=false)){
        jQuery(this).blur();
        jQuery(this).focus();
}

就像我说过的，这个解要复杂得多。这是我使用的第一个，直到我意识到下拉列表只出现在某些输入名称上。

抱歉写了这么多，我只是想确保一切都清楚。我希望这能有所帮助。

2022年4月:autocomplete="off"仍然不能在Chrome中工作，我不相信在查看了与此问题相关的Chromium bug后(可能只针对密码字段)。我看到2014年报告的问题被关闭为“WontFix”，问题仍然悬而未决，正在讨论[1][2]。据我所知，Chromium团队不相信有一个有效的用例autocomplete="off"。

总的来说，我仍然认为这两种极端策略(“总是尊重自动完成=关闭”和“从不尊重自动完成=关闭”)都是不好的。

https://bugs.chromium.org/p/chromium/issues/detail?id=914451#c66

他们的印象是，网站不会正确使用它，并决定不应用它，提出以下建议:

In cases where you want to disable autofill, our suggestion is to utilize the autocomplete attribute to give semantic meaning to your fields. If we encounter an autocomplete attribute that we don't recognize, we won't try and fill it. As an example, if you have an address input field in your CRM tool that you don't want Chrome to Autofill, you can give it semantic meaning that makes sense relative to what you're asking for: e.g. autocomplete="new-user-street-address". If Chrome encounters that, it won't try and autofill the field.

https://bugs.chromium.org/p/chromium/issues/detail?id=587466#c10

虽然这个“建议”目前对我来说是可行的，但它可能并不总是正确的，看起来团队正在进行实验，这意味着自动完成功能可能会在新版本中改变。

我们不得不求助于这个是愚蠢的，但唯一可靠的方法是尽可能地迷惑浏览器:

在不向浏览器泄露任何信息的情况下为输入命名，例如id="field1"而不是id="country"。 设置autocomplete="do-not-autofill"，基本上使用任何不会让浏览器识别为可自动填充字段的值。

2021年1月:autocomplete="off"现在按预期工作(在Chrome 88 macOS上测试)。

要做到这一点，请确保input标记位于Form标记中

2020年9月:autocomplete=" Chrome -off"禁用Chrome自动填充功能。

原答案，2015年:

对于新版本的Chrome浏览器，你只需要在密码栏中输入autocomplete="new-password"就可以了。我检查过了，工作正常。

在这次讨论中，我从Chrome开发者那里得到了一个建议: https://bugs.chromium.org/p/chromium/issues/detail?id=370363#c7

P.S. Note that Chrome will attempt to infer autofill behavior from name, id and any text content it can get surrounding the field including labels and arbitrary text nodes. If there is a autocomplete token like street-address in context, Chrome will autofill that as such. The heuristic can be quite confusing as it sometimes only trigger if there are additional fields in the form, or not if there are too few fields in the form. Also note that autocomplete="no" will appear to work but autocomplete="off" will not for historical reasons. autocomplete="no" is you telling the browser that this field should be auto completed as a field called "no". If you generate unique random autocomplete names you disable auto complete.

如果你的用户访问了不好的表单，他们的自动填充信息可能会被损坏。让他们手动进入并修复Chrome中的自动填充信息可能是他们采取的必要行动。

这些问题的其他解决方法对我都不起作用。

唯一管用的想法是这个:

它从元素中删除“name”和“id”属性并为它们赋值 1毫秒后返回。把这个放在文件里，准备好。

$(document).ready(function() {
    $('form[autocomplete="off"] input, input[autocomplete="off"]').each(function () {

                var input = this;
                var name = $(input).attr('name');
                var id = $(input).attr('id');

                $(input).removeAttr('name');
                $(input).removeAttr('id');

                setTimeout(function () {
                    $(input).attr('name', name);
                    $(input).attr('id', id);
                }, 1);
            });
});

这里有两个部分。Chrome和其他浏览器会记住之前输入的字段名的值，并基于此为用户提供一个自动完成列表(值得注意的是，密码类型的输入永远不会以这种方式记住，原因相当明显)。你可以添加autocomplete="off"来防止这种情况发生在你的电子邮件字段上。

但是，您还可以使用密码填充器。大多数浏览器都有自己的内置实现，也有许多第三方实用程序提供此功能。这个，你停不下来。这是用户自己选择保存该信息以便稍后自动填写，完全超出了应用程序的范围和影响范围。

因为display none似乎不再起作用了 添加

<input type="text" name="fakeusernameremembered"/>
<input type="password" name="fakepasswordremembered"/>

在一个div溢出隐藏，最大宽度和最大高度0px

所以它就变成了:

<div style="overflow: hidden; max-width: 0px; max-height: 0px;">
    <input type="text" name="fakeusernameremembered"/>
    <input type="password" name="fakepasswordremembered"/>
</div>
