就像Dvd Franco说的，对我来说，只有把automplete='off'在所有领域它工作。所以我把jquery规则放在$(document).ready();函数在我的主.js文件

$('form.no_autofill').attr('autocomplete','off');
$('.no_autofill input').attr('autocomplete','off');

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。

对于Angular用户:

由于autocomplete= 'off'忽略新chrome版本，chrome开发人员建议autocomplete= '假|随机字符串'，所以谷歌chrome/现代浏览器有2种类型的用户助手-

Autocomplete ='off'(防止上次缓存的建议)。 Autocomplete = 'false | random-string'(防止自动填充设置，因为'random-string'是不知道的浏览器)。

那么，在禁用这两个恼人的建议的情况下，该怎么办呢? 诀窍在这里:-

在每个输入字段中添加autocomplete = 'off'。 (或简单的Jquery)。

示例:$("input")。attr(“自动完成”,“关闭”);

从HTML代码中删除<form name='form-name'>标签，并在<div>容器中添加ng-form ='form-name'。 添加ng-form="form-name"也会保留所有的验证。

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>

我的问题是，Chrome会自动填充邮政编码，在引导自动完成界面，因为我是自动建议可能的值从我的数据库。

我必须做的事情:

将输入字段的id属性更改为“邮政编码”以外的内容 将输入字段的自动完成值更改为false 调用$('#postcode_field').autocomplete(…)我不得不用$('#postcode_field')重置自动完成属性。道具(“自动完成”,“假”);因为Boostrap的自动完成插件会自动将其更改为关闭。

除了autocomplete="off"外，还必须将值设置为空(value="")才能使其工作。
