如何根据 Class 而不是 Id 进行 Google 音译

Question

我正在做一个基于泰米尔语的 Web 应用程序。在我的应用程序中，我使用动态字段来添加用户详细信息。那么，Dynamic Fields 有多个 ids 如何做到这一点或如何使用基于 Class 的 Google Transliteration？

<script type="text/javascript" src="http://www.google.com/jsapi"></script>
<script type="text/javascript">
  // Load the Google Transliteration API
  google.load("elements", "1", {
    packages: "transliteration"
  });

  function onLoad() {
    var options = {
      sourceLanguage: 'en',
      destinationLanguage: 'ta',
      shortcutKey: 'ctrl+m',
      transliterationEnabled: true
    };

    // Create an instance on TransliterationControl with the required
    var control = new google.elements.transliteration.TransliterationControl(options);

    // Enable transliteration in the textfields with the given ids.
    var ids = ['temrorary_address', 'permanant_address', 'bankbranch', 'member_name', 'father_husband', 'workingoffice_address', ];
    control.makeTransliteratable(ids);

    // Show the transliteration control which can be used to toggle between
    // English and Hindi and also choose other destination language.
    control.showControl('translControl');
  }
  google.setOnLoadCallback(onLoad);
</script>

Answer 1

makeTransliteratable 输入可能不仅是一个 id 数组，还可能是元素引用。 所以你可以写：

// Enable transliteration in the textfields with the given Class.
var elements = document.getElementsByClassName('Type-Your-Class-Here');
control.makeTransliteratable(elements);

但如果您是动态添加字段，则无济于事。对于动态添加的字段，您必须在每次添加新字段时调用control.makeTransliteratable。
