<!DOCTYPE html>
<html lang="en-US">
<body>
<h1>My Web Page</h1>
<p>Hello everybody!</p>
<p>Translate this page:</p>
<div id="google_translate_element"></div>
<script type="text/javascript">
function googleTranslateElementInit() {
new google.translate.TranslateElement({pageLanguage: 'en'}, 'google_translate_element');
}
</script>
<script type="text/javascript" src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>
</body>
</html>
但我遇到的情况是，用户在一个英文文本框中输入文本，点击"翻译"按钮，另一个文本框就会获得西班牙语翻译文本。我尝试将"google_translate_element"替换为"es"或"Spanish"，但没有成功。有什么建议吗？
从谷歌支持中找到了解决方案，因此可以为可能需要它的人共享。您可以使用includedLanguages并列出要在下拉列表中显示的逗号分隔语言：
<!DOCTYPE html>
<html lang="en-US">
<body>
<h1>My Web Page</h1>
<p>Hello everybody!</p>
<p>Translate this page:</p>
<div id="google_translate_element"></div>
<script type="text/javascript">
function googleTranslateElementInit() {
new google.translate.TranslateElement({pageLanguage: 'en', includedLanguages: 'es', layout: google.translate.TranslateElement.InlineLayout.SIMPLE, autoDisplay: false}, 'google_translate_element');
}
</script>
<script type="text/javascript" src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>
<p>You can translate the content of this page by selecting a language in the select box.</p>
