我想转换showtimesData为showtimesByLocationByDate

任何想法,如何不使用任何第三方库,只使用纯JavaScript？否则,我可以使用哪个第三方库？

    var showtimesData = [
        {"location":"location1", "date":"31-12-2016", "time":"1:00"},
        {"location":"location1", "date":"31-12-2016", "time":"2:00"},
        {"location":"location1", "date":"01-01-2017", "time":"3:00"},
        {"location":"location1", "date":"01-01-2017", "time":"4:00"},
        {"location":"location2", "date":"31-12-2016", "time":"1:00"},
        {"location":"location2", "date":"31-12-2016", "time":"2:00"},
        {"location":"location2", "date":"01-01-2017", "time":"3:00"},
        {"location":"location2", "date":"01-01-2017", "time":"4:00"},
    ];
    var showtimesByLocationByDate = [
        {
            "location":"location1",
            "dates":[
                {
                    "date":"31-12-2016",
                    "times":["1:00","2:00"]
                },
                {
                    "date":"01-01-2017",
                    "times":["3:00","4:00"]
                }
            ]
        },
        {
            "location":"location2",
            "dates":[
                {
                    "date":"31-12-2016",
                    "times":["1:00","2:00"]
                },
                {
                    "date":"01-01-2017",
                    "times":["3:00","4:00"]
                }
            ]
        },
    ];

我正在尝试使用进度条创建范围输入。我找到了这个解决方案

input {
  -webkit-box-align: center;
  -ms-flex-align: center;
  align-items: center;
  -webkit-appearance: none;
  -moz-appearance: none;
  appearance: none;
  background: none;
  cursor: pointer;
  display: -webkit-box;
  display: -ms-flexbox;
  display: flex;
  height: 100%;
  min-height: 50px;
  overflow: hidden;
  width: 240px;
}

input:focus {
  box-shadow: none;
  outline: none;
}

input::-webkit-slider-runnable-track {
  background: #e33d44;
  content: '';
  height: 2px;
  pointer-events: none;
}

input::-webkit-slider-thumb {
  height: 18px;
  width: 28px;
  -webkit-appearance: none;
  appearance: none;
  background: #fff;
  border-radius: 8px;
  box-shadow: 5px 0 0 -8px #c7c7c7, 6px 0 0 -8px #c7c7c7, 7px 0 0 …

我想获取没有文件扩展名的文件列表。考虑我的目录的内容是：

folder
file1
file2.mp4

我的目标是file1只获得。

运行Get-ChildItem -Exclude *.* -File没有返回任何结果。

运行Get-ChildItem -Exclude *.*返回folder并file1。

运行Get-ChildItem -File返回file1并file2.mp4。

知道是否有任何方法可以使用 Get-ChildItem 仅返回file1？

我有一个带有对象键的hashmap和另一个对象的arraylist作为值:

HashMap<Object1, ArrayList<Object2>> map;

Object2可以属于多个Object1.我想扭转它,使它成为:

HashMap<Object2, ArrayList<Object1>> reversed;

我怎样才能做到这一点？

我已经看到了具有对象键和对象值的哈希映射的解决方案,但不同的是,我的问题围绕一个arraylist作为值.
