c# - 如何为多个动态文本框启用 Google 音译 (ASP.Net)

Question

以下是将 Google Transliteration 代码集成到 ASP.Net Pages 中的示例代码(随处可用)。

但我的问题是，如何在将在运行时生成的文本框中启用音译？此脚本需要文本框的 ID 以应用音译。但是我的文本框将在运行时生成。

这行代码需要一个替代方案:
control.makeTransliteratable(['transliterateTextarea']);

  //Script Starts here

  // Load the Google Transliterate API
  google.load("elements", "1", {
        packages: "transliteration"
      });

  function onLoad() {
    var options = {
        sourceLanguage:
            google.elements.transliteration.LanguageCode.ENGLISH,
        destinationLanguage:
            [google.elements.transliteration.LanguageCode.HINDI],
        shortcutKey: 'ctrl+g',
        transliterationEnabled: true
    };

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

    // Enable transliteration in the textbox with id
    // 'transliterateTextarea'.
    control.makeTransliteratable(['transliterateTextarea']);
  }
  google.setOnLoadCallback(onLoad);

 //End here

使用 RegisterStartupScript。 RegisterStartupScript 将在页面加载完成后执行。

function EnableTransalation(ctrlId) {
    //Script Starts here

    // Load the Google Transliterate API
    google.load('elements', '1', {
        packages: 'transliteration'
    });

    function onLoad() {
        var options = {
            sourceLanguage:
            google.elements.transliteration.LanguageCode.ENGLISH,
            destinationLanguage:
            [google.elements.transliteration.LanguageCode.HINDI],
            shortcutKey: 'ctrl+g',
            transliterationEnabled: true
        };

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

        // Enable transliteration in the textbox with id
        // 'transliterateTextarea'.
        control.makeTransliteratable(["'" + ctrlId + "'"]);
    }
    google.setOnLoadCallback(onLoad);

    //End here
}

在后面的代码中，

protected override void OnPreRender(EventArgs e)
{
  Page.ClientScript.RegisterStartupScript(GetType(), "EnableTransalation", "EnableTransalation('" + ctrl.ClientID + "')", true);
}
