我遇到了chrome自动填充行为的几个形式的问题。

表单中的字段都有非常常见和准确的名称,例如“email”、“name”或“password”,并且它们还设置了autocomplete=“off”。

自动完成标志已经成功禁用了自动完成行为,当你开始输入时,会出现一个下拉的值,但没有改变Chrome自动填充字段的值。

这种行为是可以的,除了chrome填充输入不正确,例如填充电话输入与电子邮件地址。客户抱怨过这个问题,所以它被证实在很多情况下都发生了,而不是我在我的机器上本地操作的某种结果。

目前我能想到的唯一解决方案是动态生成自定义输入名称,然后在后端提取值,但这似乎是一种相当笨拙的解决这个问题的方法。是否有任何标签或怪癖,改变自动填充行为,可以用来解决这个问题?

使用css text-security: disc而不使用type=password。

html

<input type='text' name='user' autocomplete='off' />
<input type='text' name='pass' autocomplete='off' class='secure' />

or

<form autocomplete='off'>
    <input type='text' name='user' />
    <input type='text' name='pass' class='secure' />
</form>

css

input.secure {
    text-security: disc;
    -webkit-text-security: disc;
}

尝试在值中添加一个空格:

<input type="email" name="email" value="&nbsp;">
<input type="password" name="password" value="&nbsp;">

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。

对于用户名密码组合,这是一个很容易解决的问题。Chrome启发式查找模式:

<input type="text">

紧随其后的是:

<input type="password">

简单地通过使其无效来中断这个过程:

<input type="text">
<input type="text" onfocus="this.type='password'">

Boom,谷歌Chrome和其他人尝试击败这然后。

我能够得到这个实现今天2017年9月7日,但使用在我的MVC视图中生成的随机字符串的FormCollection。

我会首先在我的登录页面的索引控制器中获得一个新的随机密钥,加密并创建一个新的完全唯一的随机字符串(我实际上使用了一个256位的cypher来执行此操作,以及一个唯一的cypher和认证密钥),然后在每个字符串的末尾附加纯文本“用户名”和“密码”,以帮助我从响应视图控制器识别用户名和密码。你也可以把这个普通字符串改成任何东西,只要你知道它的模式并且它是唯一的。

在我看来,我然后适当地使用这些变量,然后在响应控制器中—通过FormCollection搜索并找到匹配的变量—然后使用该项的Key-Value作为相应的用户名和密码进行适当的处理。

The other issue i had which i think is sneaky of Chrome, is that any Any thoughts ? <style> @@font-face { font-family: 'password'; font-style: normal; font-weight: 400; src: url(https://jsbin-user-assets.s3.amazonaws.com/rafaelcastrocouto/password.ttf); } </style> <input type="text" name="@Model.UsernameRandomNameString" /> <input style="font-family: 'password'" type="text" name="@Model.PasswordRandomNameString" /> LogOnModel model = new LogOnModel() { UsernameRandomNameString = Cryptography.SimpleEncrypt("Username", UniqueGeneratorKey, UniqueGeneratorKey) + "Username", PasswordRandomNameString = Cryptography.SimpleEncrypt("Password", UniqueGeneratorKey, UniqueGeneratorKey) + "Password", }; I think it a hell of a workaround, but hey it works, and i think it could also be future proof unless google determines the URL of the page has key words in it, then appropriately just adds its stupid extensions on top on any input field - but that's a little drastic.

为用户名字段输入值' '(空格)。

<input type = 'text' value = ' ' name = 'username' />

如果您曾经用用户输入的值填充用户名,如果没有用户输入的值,则编码输入' '。

编辑:我还不得不改变'用户名'字段有一个其他的名字,而不是'用户名',例如。“nameofuser”
