我想显示给定startTime，endTime和interval的持续时间数组。
let value = {
interval: '00:30:00',
startTime: '03:00:00',
endTime: '20:00:00'
};
样本输出必须是具有给定间隔的持续时间数组
-startTime减去时间间隔，因此新 startTime = 02:30:00
[0] => '02:30 am - 03:00 am'
[1] => '03:00 am - 03:30 am'
[2] => '03:30 am - 04:00 am'
[3] => '04:00 am - 04:30 am'
......
[n] => '07:30 pm - 08:00 pm'
这是我的职能
function showTimeIntervals(value) {
let result = value.interval.split(",");
let start = "";
let timeNotation = '';
let time = '';
for(let i in result) {
let hr = moment(result[i], 'HH:mm').format('HH');
let min = moment(result[i], 'HH:mm').format('mm');
hr = (hr != 0) ? parseInt(hr, 10) : '';
min = (min != 0) ? parseInt(min, 10) : '';
if(hr != 0) {
time = hr;
timeNotation = 'hour';
start = moment(value.startTime, 'hh:mm a').subtract(hr, 'hour');
} else {
time = min;
timeNotation = 'minutes';
start = moment(value.startTime, 'hh:mm a').subtract(min, 'minutes');
}
}
var end = moment(value.endTime, 'hh:mm a');
if(end < start)
end = end.add(1, 'd');
var finalResult = [];
var current = moment(start);
while (current <= end) {
finalResult.push(current.format('hh:mm a'));
current.add(time, timeNotation);
}
return finalResult;
}
但这给了个人时间而不是持续时间
[0] => '02:30 am'
[1] => '03:00 am'
[2] => '03:30 am'
[3] => '04:00 am'
......
[n] => '08:00 pm'

js可以立即做到这一点的最简单方法吗？
这是另一个使用moment.js生成间隔的选项。
let value = {
interval: '00:30:00',
startTime: '03:00:00',
endTime: '20:00:00'
};
var inputDataFormat = "HH:mm:ss";
var outputFormat = "HH:mm a";
var tmp = moment(value.interval, inputDataFormat);
var dif = tmp - moment().startOf("day");
var startIntervalTime = moment(value.startTime, inputDataFormat).add(-dif, "ms");
var endIntervalTime = moment(value.startTime, inputDataFormat);
var finishTime = moment(value.endTime, inputDataFormat);
function prepareIntervals() {
var intervals = [];
while(startIntervalTime < finishTime) {
var format = startIntervalTime.format(outputFormat) + " - " + endIntervalTime.format(outputFormat);
intervals.push(format);
startIntervalTime.add(dif, "ms");
endIntervalTime.add(dif, "ms");
}
return intervals;
}
console.dir(prepareIntervals());<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.19.1/moment.js"></script>本文收集自互联网，转载请注明来源。
