获取时间区间数据

原数据：

结果：

var arr = [        {            "label": "00:00-00:15",            "count": 3        },        {            "label": "00:15-00:30",            "count": 3        },        {            "label": "12:00-12:15",            "count": 3        },        {            "label": "12:15-12:30",            "count": 3        },        {            "label": "12:30-12:45",            "count": 3        }]/** * arr 原数据 * startDate 开始时间 默认传 00:00:00 * endDate 结束时间 默认传 00:30:00 * */ const getEchoTime = (arr,startDate,endDate) =>{    let newArr  = [];    let start = startDate.substring(0,5);    let end = endDate.substring(0,5);     newArr = arr.filter(({label}) => {    const times = label.split('-');     return times[0] >= start && times[1] <= end;       })    return newArr; } console.log( getEchoTime(arr,'00:00:00','00:30:00'))
