Javascript 检查范围是否重叠

Question

我有以下 javascript- 对象:

function checkTimeOverlapping() {

        var scheduleIntervalContainerWrappers = [];

        var scheduleIntervalContainerWrapper1 = {};
        scheduleIntervalContainerWrapper1.start = '08:00';
        scheduleIntervalContainerWrapper1.end = '10:00';
        scheduleIntervalContainerWrappers.push(scheduleIntervalContainerWrapper1);

        var scheduleIntervalContainerWrapper2 = {};
        scheduleIntervalContainerWrapper2.start = '09:00';
        scheduleIntervalContainerWrapper2.end = '14:00';
        scheduleIntervalContainerWrappers.push(scheduleIntervalContainerWrapper2);

         ...

        alert(scheduleIntervalContainerWrappers);   
    }

我将检查scheduleIntervalContainerWrapper是否与开始时间和结束时间重叠。是否有可能在纯js中做到这一点？

带有一些测试用例的提案。转换为分钟。

function overlapping(a, b) {
    function getMinutes(s) {
        var p = s.split(':').map(Number);
        return p[0] * 60 + p[1];
    }
    return getMinutes(a.end) > getMinutes(b.start) && getMinutes(b.end) > getMinutes(a.start);
}

document.write(overlapping({ start: '00:00', end: '00:00' }, { start: '00:00', end: '00:00' }) + '<br>');
document.write(overlapping({ start: '00:00', end: '02:00' }, { start: '00:00', end: '02:00' }) + '<br>');
document.write(overlapping({ start: '00:00', end: '10:00' }, { start: '02:00', end: '10:00' }) + '<br>');
document.write(overlapping({ start: '20:00', end: '22:00' }, { start: '20:00', end: '21:00' }) + '<br>');
document.write(overlapping({ start: '20:00', end: '21:00' }, { start: '20:00', end: '22:00' }) + '<br>');
document.write(overlapping({ start: '02:00', end: '03:00' }, { start: '01:00', end: '02:30' }) + '<br>');
document.write(overlapping({ start: '00:00', end: '05:00' }, { start: '05:00', end: '10:00' }) + '<br>');
document.write(overlapping({ start: '10:00', end: '15:00' }, { start: '00:00', end: '08:00' }) + '<br>');
