Question

我有一个代码，可以确定网站上的访问者使用哪种语言，并将用户转到正确的页面。我想在转发用户之前添加3秒的延迟。这是可能的吗？

<script>
  var lang = window.navigator.language;
  var userLang = window.navigator.userLanguage;
  if(window.location.href.indexOf('/?edit') === -1) {
    if (lang == "sv-SE" || userLang == "sv-SE") {
      window.location.href = window.location.href + "se";
    } else {
      window.location.href = window.location.href + "en";
    }
  }
</script>

Answer 1

使用setTimeout在指定的超时后触发函数调用。

if (window.location.href.indexOf('/?edit') === -1) {
  const lang = window.navigator.language;
  const userLang = window.navigator.userLanguage;
  let pageLang = 'en';

  if (lang == "sv-SE" || userLang == "sv-SE") pageLang = 'se';

  window.setTimeout(() => {
    window.location.href + pageLang;
  }, 3000);
}

Answer 2

使用此setTimeout或setInterval，例如：

setTimeout(function(){ 
// any staff
},3000);

对您来说，就像：

 if (lang == "sv-SE" || userLang == "sv-SE") {
setTimeout(function(){ 
      window.location.href = window.location.href + "se";
},3000);
    } else {
setTimeout(function(){ 
      window.location.href = window.location.href + "en";
},3000);
    }

Answer 3

如果不想使用setTimeout，可以使用sleep()，

function sleep( millisecondsToWait )
{
    var now = new Date().getTime();
    while ( new Date().getTime() < now + millisecondsToWait )
    {
        /* do nothing; this will exit once it reaches the time limit */
        /* if you want you could do something and exit */
    }
}


console.log('something');
sleep(3000);
console.log('hello');

延迟确定用户的语言
