我有返回给我的JSON数据，我试图在两个日期之间过滤数据，结果不是很好。 代码在这里，您看到的注释掉的内容是我已经尝试过但没有效果的（日期格式是dd-MM-yyyy，如果您想知道的话）。
let data = [
{ date : "06-06-2020", toll:1, Province: "Ontario" },
{ date : "06-06-2020", toll:10, Province: "Alberta" },
{ date : "07-06-2020", toll:2, Province: "Ontario" },
{ date : "08-06-2020", toll:2, Province: "Alberta" },
{ date : "09-06-2020", toll:15, Province: "Alberta" },
{ date : "08-06-2020", toll:18, Province: "Ontario" },
{ date : "07-06-2020", toll:11, Province: "Nova Scotia" },
{ date : "07-06-2020", toll:1, Province: "Ontario" },
{ date : "10-06-2020", toll:10, Province: "Manitoba" },
{ date : "11-06-2020", toll:9, Province: "Manitoba" },
{ date : "11-06-2020", toll:3, Province: "Ontario" },
{ date : "07-06-2020", toll:89, Province: "Manitoba" },
{ date : "06-06-2020", toll:90, Province: "Ontario" },
{ date : "06-06-2020", toll:45, Province: "Nova Scotia" },
{ date : "13-06-2020", toll:55, Province: "Ontario" },
{ date : "13-06-2020", toll:1, Province: "Ontario" },
{ date : "13-06-2020", toll:17, Province: "Ontario" },
{ date : "12-06-2020", toll:2, Province: "Nova Scotia" },
{ date : "08-06-2020", toll:8, Province: "Ontario" },
{ date : "08-06-2020", toll:9, Province: "Newfoundland " },
{ date : "06-06-2020", toll:11, Province: "Newfoundland " },
{ date : "12-06-2020", toll:100, Province: "Ontario" },
{ date : "06-06-2020", toll:13, Province: "Ontario" }
];
function GetData(){
let startDate, endDate;
startDate = new Date("03-06-2020");
endDate = new Date("13-06-2020");
console.log(data.filter(f => f.Province == "Ontario"));
//let betweenDate = data.filter(f => {
// let date = new Date(f.date);
// return (f.date >= startDate && f.date <= endDate && f.Province == "Ontario");
//});
//
//let betweenDate = data.filter(f => {
// return (f.date >= startDate && f.date <= endDate && f.Province == "Ontario");
//});
//console.log(betweenDate);
}
GetData();
“日期格式是dd-MM-yyyy，如果你想知道”这就是问题所在。 新日期不知道您正在使用该格式。 下面，我添加了一个方法，将其转换为yy-MM-dd。
您还需要比较您创建的date变量，而不是f.date:
null
// Minified, but same data as yours
let data = [{date:"06-06-2020",toll:1,Province:"Ontario"},{date:"06-06-2020",toll:10,Province:"Alberta"},{date:"07-06-2020",toll:2,Province:"Ontario"},{date:"08-06-2020",toll:2,Province:"Alberta"},{date:"09-06-2020",toll:15,Province:"Alberta"},{date:"08-06-2020",toll:18,Province:"Ontario"},{date:"07-06-2020",toll:11,Province:"Nova Scotia"},{date:"07-06-2020",toll:1,Province:"Ontario"},{date:"10-06-2020",toll:10,Province:"Manitoba"},{date:"11-06-2020",toll:9,Province:"Manitoba"},{date:"11-06-2020",toll:3,Province:"Ontario"},{date:"07-06-2020",toll:89,Province:"Manitoba"},{date:"06-06-2020",toll:90,Province:"Ontario"},{date:"06-06-2020",toll:45,Province:"Nova Scotia"},{date:"13-06-2020",toll:55,Province:"Ontario"},{date:"13-06-2020",toll:1,Province:"Ontario"},{date:"13-06-2020",toll:17,Province:"Ontario"},{date:"12-06-2020",toll:2,Province:"Nova Scotia"},{date:"08-06-2020",toll:8,Province:"Ontario"},{date:"08-06-2020",toll:9,Province:"Newfoundland "},{date:"06-06-2020",toll:11,Province:"Newfoundland "},{date:"12-06-2020",toll:100,Province:"Ontario"},{date:"06-06-2020",toll:13,Province:"Ontario"}];
