JS 获取时间字符串区间

function getDiffDate(start, end) {
 
    var startTime = getDate(start);
 
    var endTime = getDate(end);
 
    var dateArr = [];
 
    while ((endTime.getTime() - startTime.getTime()) > 0) {
 
        var year = startTime.getFullYear();
 
        var month = startTime.getMonth().toString().length === 1 ? "0" + (parseInt(startTime.getMonth().toString(),10) + 1) : (startTime.getMonth() + 1);
 
        var day = startTime.getDate().toString().length === 1 ? "0" + startTime.getDate() : startTime.getDate();
 
        dateArr.push(year + "-" + month + "-" + day);
 
        startTime.setDate(startTime.getDate() + 1);
 
    }
 
    return dateArr;
 
}

 

function getDate (datestr) {
 
    var temp = datestr.split("-");
 
    if (temp[1] === '01') {
 
        temp[0] = parseInt(temp[0],10) - 1;
 
        temp[1] = '12';
 
    } else {
 
        temp[1] = parseInt(temp[1],10) - 1;
 
    }
 
    //new Date()的月份入参实际都是当前值-1
 
    var date = new Date(temp[0], temp[1], temp[2]);
 
    return date;
 
}

 

 

console.info(getDiffDate('2018-05-27', '2018-06-31'));
