Js 根据时间范围获取之间的日期

function get(start_time,end_time){
    var bd = new Date(start_time),be = new Date(end_time);
    var bd_time = bd.getTime(), be_time = be.getTime(),time_diff = be_time - bd_time;
    var d_arr = [];
    for(var i=0; i<= time_diff; i+=86400000){
            var ds = new Date(bd_time+i);
            d_arr.push((ds.getMonth()+1)+'月'+ds.getDate()+'日')
    }
    alert(d_arr);
}
get('2017-02-02','2017-03-28')
