javascript - 我可以获得该向量时间的天数吗？

Question

我得到了这段代码，可以让我以小时为单位生成 future 五天的预测

我想获取矢量输出的 5 天名称，我遇到了一些问题，因为它与 GetHours 一起工作，并且当时会发生变化，所以有点困难。

var d = new Date();
var time = [];
var horas = (d.getHours());
var num = 0;
for (i = 1; i < 40; i++) {
  if (horas >= 24) {
    horas === 0;
  } else {
    horas = horas + 3;
    if (horas >= 24) {
      horas = 0;
    }
  }
  time.push((horas + ':00'));

}
console.log(time);

输出如下:

(39) ["3:00" ,"6:00" ,"9:00" ,"12:00" ,"15:00" ,"18:00" ,"21:00" ,"0:00" ,"3:00" ,"6:00" ,"9:00" ,"12:00" ,"15:00" ,"18:00" ,"21:00" ,"0:00" ,"3:00" ,"6:00" ,"9:00" ,"12:00" ,"15:00" ,"18:00" ,"21:00" ,"0:00" ,"3:00" ,"6:00" ,"9:00" ,"12:00" ,"15:00" ,"18:00" ,"21:00" ,"0:00" ,"3:00" ,"6:00" ,"9:00" ,"12:00" ,"15:00" ,"18:00" ,"21:00"]

预期结果时间向量和天向量

(5)["Monday","Tuesday","Wednesday","Thursday","Friday"];

Answer 1

如果您正在查找当前日期中的 5 天名称，那么您可以通过维护一个 weekDays 数组来实现，如下所示:

var d = new Date();
    var time = [];
    var expectedDays = [];
    var weekDays = ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"];
    var horas = (d.getHours());
    var num = 0;
    for (i = 1; i < 40; i++) {
    	
      if (horas >= 24) {
        horas === 0;
        expectedDays.push(weekDays[(d.getDay()+(num++))%7]);
      } else {
        horas = horas + 3;
        if (horas >= 24) {
          horas = 0;
          expectedDays.push(weekDays[(d.getDay()+(num++))%7]);
        }
      }
      time.push((horas + ':00'));
    
    }
    console.log(time);
    console.log(expectedDays);
