js实现获取两个日期之间筛选出指定周日制的方法

var  start =  "2017-5-25" ;
var  end =  "2017-6-5" ;
var  startTime =  new  Date(start);
var  endTime =  new  Date(end)
var  timeArr = [];
var  weekDay = [ "1" , "2" , "3" ]
while ((endTime.getTime()-startTime.getTime())>=0){
  var  year = startTime.getFullYear();
  var  month = startTime.getMonth().toString().length==1? "0" +(startTime.getMonth() + 1).toString():startTime.getMonth() + 1;
  var  day = startTime.getDate().toString().length==1? "0" +startTime.getDate():startTime.getDate();
  var  date = year+ "-" +month+ "-" +day;
  for ( var  i = 0;i < weekDay.length; i++){
    if ( new  Date(date).getDay() == weekDay[i]){
        timeArr.push(date);
    }
  }
  console.log(date);
  startTime.setDate(startTime.getDate()+1);

}
console.log(timeArr);
