javascript - 过滤两个日期之间的日期数组

问题描述

我有一系列日期。我正在尝试删除不在两个日期之间的日期。但是我得到了一些甚至早于“开始”日期的日期。我究竟做错了什么？

$scope.filterUpcomingEvents = function() {

    $scope.arrayOfEventData = JSON.parse(JSON.stringify($scope.tempArray));

    console.log($scope.tempArray, "arrayofeve");
    for (let d = 0; d < $scope.arrayOfEventData.length; d++) {
        debugger;
        console.log(d);
        console.log(new Date($scope.tempArray[d].event_date), "from", $scope.upcomingEventFrom);
        console.log(new Date($scope.tempArray[d].event_date) < $scope.upcomingEventFrom);
        console.log(new Date($scope.tempArray[d].event_date), "to", $scope.upcomingEventTo);
        console.log(new Date($scope.tempArray[d].event_date) > $scope.upcomingEventTo);
        console.log("---");
        if (new Date($scope.arrayOfEventData[d].event_date) < $scope.upcomingEventFrom || new Date($scope.arrayOfEventData[d].event_date) > $scope.upcomingEventTo) {
            $scope.arrayOfEventData.splice(d, 1);
        }
    }
    console.log($scope.arrayOfEventData, "after splice");
}

在控制台中，虽然我得到了一些比较，但它并没有被拼接。当我看到 finaly 数组时，它仍然具有应该被拼接的值，尽管它是 true 并且进入if.

解决方案

当您从递增循环的同一个数组拼接时，数组会修改并且项目会移动。因此，您可能会错过一次迭代。

你可以做的一件事是使用while循环向后循环，这样你就不会循环你拼接的方向。

let i = $scope.arrayOfEventData.length;
while(i--){
  // your code
}
