【问题讨论】：
this:<form autocomplete='off'> exists 不确定 chrome 是否支持它。
【参考方案1】：
您正在检查文本框 keyup 事件的电子邮件验证，但 jquery 不将自动填充视为 keyup 事件。它甚至无法使用自动填充读取填充值。
【讨论】：
【参考方案2】：您可以使用focusout 事件代替keyup 事件来解决您的问题。
这是更新的jsfiddle

var phoneno = /^\d9|\d10|\d11$/;
return phoneno.test(phone);
$('input[type="tel"]').on('keyup', function()
var $label = $(this).closest('label');

if ($(this).is('#phone'))
if (phoneNumber($(this).val()))
$label.attr('data-valid', 'valid');
else
$label.attr('data-valid', 'error');
console.log("this works")
else
$label.attr('data-valid', 'valid');
console.log("this works")
else
$label.removeAttr('data-valid');
console.log("this works")
);
function validateEmail(email)

【参考方案3】：如果这让您感到困扰，我建议您使用一些技巧禁用自动填充功能。使用 DOM 处理浏览器功能并不总是一个好方法。
Chrome 会忽略自动填充的只读字段。您可以将输入字段加载为只读，并在悬停时使其可编辑
<input type="email" name="email" readonly>
