如果你使用jQuery，你可以这样做:

$(document).ready(function(){$("input.autocompleteOff").attr("autocomplete","off");});

并在你想要的地方使用autocompleteOff类:

<input type="text" name="fieldName" id="fieldId" class="firstCSSClass otherCSSClass autocompleteOff" />

如果你想要所有的输入都是autocomplete=off，你可以简单地使用:

$(document).ready(function(){$("input").attr("autocomplete","off");});

Note that there's some confusion about location of the autocomplete attribute. It can be applied either to the whole FORM tag or to individual INPUT tags, and this wasn't really standardized before HTML5 (that explicitly allows both locations). Older docs most notably this Mozilla article only mentions FORM tag. At the same time some security scanners will only look for autocomplete in INPUT tag and complain if it's missing (even if it is in the parent FORM). A more detailed analysis of this mess is posted here: Confusion over AUTOCOMPLETE=OFF attributes in HTML forms.

if (document.getElementsByTagName) {
    var inputElements = document.getElementsByTagName("input");
    for (i=0; inputElements[i]; i++) {
        if (inputElements[i].className && (inputElements[i].className.indexOf("disableAutoComplete") != -1)) {
            inputElements[i].setAttribute("autocomplete","off");
        }
    }
}

我在2020年就做到了!

我基本上创建了一个css类，对我的输入应用-webkit-text-security。

这里有一个最近讨论的链接: https://stackoverflow.com/a/64471795/8754782

这个解决方案对我很管用:

$('form,input,select,textarea').attr("autocomplete", "nope");

如果你想在这个区域使用自动填充:在元素中添加autocomplete="false" 例:

<input id="search" name="search" type="text" placeholder="Name or Code" autcomplete="false">

用JavaScript设置怎么样?

var e = document.getElementById('cardNumber');
e.autocomplete = 'off'; // Maybe should be false

这并不完美，但您的HTML将是有效的。
