如何更改背景以匹配用户的天气条件和一天中的时间？

Question

到目前为止，我的代码正在运行，但仅适用于白天的照片。我忘了为用户的位置放入夜间照片。因此，当它说晚安并且天气状况说晴朗的天空时，背景应该变成晴朗的天空和夜间照片，而不是像我已经拍过的晴天照片。如何按位置和一天中的时间将背景更改为用户的天气？这是我的 codepen 的链接，以防您希望看到它的实际效果。 https://codepen.io/Brown95/pen/MvvBLK

var weatherImage = "";

  var imagePhoto = {

    }

    $('body').css('background-image', 'url(' + weatherImage + ')');

这是获取当前日期时间的方法：

console.log(new Date());

在 w3c 上，您会发现许多函数可以从日期中检索特定数据：
