Why redirect on my website only works for once?
Question
On my website, I made a redirect page to redirect people according to their languages and browsers. But it only works once, when I visit my website again, it won't redirect.
HTML:
<html lang="zh-CN">
<head>
<script>
function redirect(){
// redirect according to browsers
var temp = window.navigator.userAgent.toUpperCase();
var charHead = temp.indexOf('MSIE');
var charLast = temp.indexOf(";", charHead);
var ieVersion = temp.substring(charHead, charLast);
ieVersion = ieVersion.split(' ')[1];
if (ieVersion <= 8) {
window.location.href="https://compat.windowsme.xyz:914";
}
if (localStorage.getItem("visit") == null)
{
// redirect according to user language
console.log("redirecting...")
var language = navigator.language || navigator.browserLanguage; //for IE
if (language == 'zh-CN'){
document.location.href = 'zh-index.html';
}
else if (language == 'zh-HK' || language == 'zh-TW'){
document.location.href = 'hant-index.html';
}
else {
document.location.href = 'en-index.html';
}
}
localStorage.setItem("visit", new Date());
redirect()
}
</script>

</html>

It's because on the second visit the item in LocalStorage is not null anymore. Why do you store this information? If you remove the if handler, it will work on every site visit.
