为您的网站异步加载Google Translate小部件的方法？

Question

有没有办法为您的网站异步加载Google Translate小部件？

我尝试将其放在页面底部,但#google_translate_element容器仍为空.

<!-- Asynchronous Google Translate -->
<script type="text/javascript">
function googleTranslateElementInit() {
  new google.translate.TranslateElement({pageLanguage: 'en', includedLanguages: 'ar,bg,bn,de,el,eo,es,en,fr,hi,id,it,iw,ja,ko,pl,pt,ru,th,tr,vi,zh-CN', layout: google.translate.TranslateElement.InlineLayout.SIMPLE, gaTrack: true, gaId: 'UA-1234-1'}, 'google_translate_element');
}

(function() {
  var googleTranslateScript = document.createElement('script');
  googleTranslateScript.type = 'text/javascript';
  googleTranslateScript.async = true;
  googleTranslateScript.src = '//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit';
  ( document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0] ).appendChild( googleTranslateScript );
})();
</script>

您的代码中似乎有几个问题.但你的基本想法是合理的.

假设<div id="google_translate_element"></div>在脚本标记之前定义了以下内容:

<!-- Asynchronous Google Translate -->
<script type="text/javascript">
  function googleTranslateElementInit() {
    new google.translate.TranslateElement({pageLanguage: 'en',
      includedLanguages: 'ar,bg,bn,de,el,eo,es,en,fr,hi,id,it,iw,ja,ko,pl,pt,ru,th,tr,vi,zh-CN',
      layout: google.translate.TranslateElement.InlineLayout.SIMPLE,
      gaTrack: true, gaId: 'UA-37652767-1'}, 'google_translate_element');
  }

  var googleTranslateScript = document.createElement('script');
  googleTranslateScript.type = 'text/javascript';
  googleTranslateScript.async = true;
  googleTranslateScript.src = 'http://translate.google.com/translate_a/element.js?cb=googleTranslateElementInit';
  ( document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0] ).appendChild(googleTranslateScript);
</script>

当我将它全部放在HTML文件中并加载到chrome中时,至少它对我有用.

当然,可以将var声明和后续行放在$(document).ready函数中(或者如果不使用jQuery,则以其他方式放置).然后之间的顺序div和script将不再后果.
