使用如下代码实现中英文网页切换。

<script>

<!--

if (navigator.appName == 'Netscape')

var language = navigator.language;

else

var language = navigator.browserLanguage;

if (language.indexOf('zh-cn') > -1) document.location.href = 'https://www.williamlong.info/';

else if (language.indexOf('en') > -1) document.location.href = 'https://www.williamlong.info/index.htm';

else

document.location.href = 'https://www.williamlong.info/';

//-->

</script>
