如何禁用MobileSafari自动选择？

  input[type="text"],
  input[type="email"],
  input[type="number"],
  input[type="date"],
  input[type="password"],
  input[type="search"],
  input[type="tel"],
  input[type="time"],
  input[type="url"],
  textarea {
    -webkit-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
  }
</style>

  document.addEventListener('touchstart', function(event) {
    event.preventDefault();
  });
</script>
