我有一个包含不同日期的数组:
let days = ["2018-09-02", "2018-10-06", "2018-10-12", "2018-10-24", "2018-11-02", "2018-11-04"];
如何检测哪一天是 future 距离今天最近的一天？
我当前的状态可以检测明天是否在数组中，但我不知道当明天不存在时如何获取 future 最近的一天。
let nextDay = day.add(1, 'days').format('YYYY-MM-DD');
for (let i = 0; i < days.length; i++) {
if (day[i] === nextDay) {
// next day is part of the array
console.log(nextDay);
}
}
最佳答案
一种可能是从当前日期中减去每个日期，看看哪个日期是距离正天数最少的日期。
示例:
let days = ["2018-09-02", "2018-10-06", "2018-10-12", "2018-10-30", "2018-11-02", "2018-11-04", "2019-01-01"];
let curDay = moment().format('YYYY-MM-DD');
let closestDay;
let closestDiff;
for (let i = 0; i < days.length; i++) {
let diff = moment(days[i]).diff(curDay, 'days');
if(diff > 0){
if(closestDiff === undefined) {
closestDay = days[i];
closestDiff = diff;
} else if(diff < closestDiff) {
closestDay = days[i];
closestDiff = diff;
}
}
}
if(closestDay === undefined) closestDay = "no days found in the future";
document.getElementById("closest-future").innerHTML = closestDay;<!DOCTYPE html>
