Javascript/Jquery 类 Google 按钮点击时翻译（带标志）

Question

有什么好的例子可以让我在 html 页面内使用 Google Translate 进行翻译吗？我的意思是，如果我点击德国国旗（按钮）而不是翻译成德语等......我的问题是如何为特定语言模拟这个组合框？ https://www.w3schools.com/howto/howto_google_translate.asp

谢谢

您可以隐藏此自动创建的选择字段并动态设置它的值，方法是遍历每个选项字段以搜索您可以通过输入字段选择的所需语言。

希望对您有所帮助：

<!DOCTYPE html>
<html lang="en-US">
<body>

<h1>My Web Page</h1>

<p>Hello everybody!</p>

<p>Translate this page.</p>

<!-- hide auto-created selection field completely by hiding it's container -->
<div id="google_translate_element" style="display:none"></div>

<p>You can translate the content of this page by selecting a language in the input field.</p>

<!-- flag: you can choose language here: en, de, af etc. -->
<input value="en" id="language"/>
<button onclick="changeLanguageByButtonClick()">Translate</button>

</body>
<script type="text/javascript">

function googleTranslateElementInit() {
  new google.translate.TranslateElement({pageLanguage: "en"}, 'google_translate_element');
}

function changeLanguageByButtonClick() {
  var language = document.getElementById("language").value;
  var selectField = document.querySelector("#google_translate_element select");
  for(var i=0; i < selectField.children.length; i++){
    var option = selectField.children[i];
    // find desired langauge and change the former language of the hidden selection-field 
    if(option.value==language){
       selectField.selectedIndex = i;
       // trigger change event afterwards to make google-lib translate this side
       selectField.dispatchEvent(new Event('change'));
       break;
    }
  }
}
</script>

<script type="text/javascript" src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>

</html>
