javascript - window.navigator.systemLanguage 字符串问题

Question

我有这个脚本来获取浏览器的语言并打开本地化的特定索引

       var language = window.navigator.systemLanguage;

if (language == "it-IT" || language == "it-it" || language == "ita-IT" || language == "it-ITA" || language == "it" ||language == "IT" ||language == "ita" ||language == "italiano" || language == "italian")
{
    location.href = "index_it.html";
}
else{
    location.href = "index_esp.html";
}

不幸的是，它只适用于 Internet Explore，但在 Firefox 和 Chrome 中始终打开 index_esp.html 也适用于意大利语浏览器

如何获取正确的语言String ID？ (如果这是问题的原因)

Answer 1

您可以同时尝试“systemLanguage”和“language”:

var language = window.navigator.systemLanguage || window.navigator.language;

将它转换为小写也会让你的生活更轻松:

language = language.toLowerCase();
