如何更改Safari中iPhone虚拟键盘上"Go"按钮的文本？

document.addEventListener('DOMContentLoaded', function() {
  var inputs = document.getElementsByTagName('input');
  for (var i = 0; i< inputs.length; i++) {
    if (inputs[i].type === 'submit' || inputs[i].type === 'button') {
      inputs[i].blur();
      inputs[i].focus();
    }
  }
});

input[type="submit"], input[type="button"] {
  -webkit-appearance: none;
  -webkit-user-select: none;
  cursor: pointer;
  font-size: 16px;
  text-align: center;
  color: white;
  background-color: #007AFF;
  border: none;
  border-radius: 4px;
  padding: 6px 12px;
  margin: 0;
  width: auto;
  display: inline-block;
  line-height: 1.2;
  text-decoration: none;
  touch-action: manipulation;
}

input[type="submit"]::-webkit-search-decoration, input[type="button"]::-webkit-search-decoration {
  display: none;
}

input[type="submit"]::-webkit-search-cancel-button, input[type="button"]::-webkit-search-cancel-button {
  display: none;
}

input[type="submit"]::before, input[type="button"]::before {
  content: "搜索";
  display: inline-block;
  margin-right: 5px;
  font-size: 16px;
  font-weight: bold;
  color: white;
  text-align: center;
  text-decoration: none;
}
