我想隐藏所有的电子邮件地址的发件人使用css或一些其他方式

<span class="email">example@example.com</span>

.email::before {
  content: attr(data-email);
  display: none;
}

.email {
  unicode-bidi: bidi-override;
  direction: rtl;
}

.email::after {
  content: attr(data-email);
  unicode-bidi: bidi-override;
  direction: ltr;
}

<span id="email">example@example.com</span>

var emailElement = document.getElementById("email");
var email = emailElement.innerHTML;
var hiddenEmail = email.replace(/./g, "*");
emailElement.innerHTML = hiddenEmail;
