我不确定这是否是您想要的，但您可以实现这一点，例如，像这样。

＆＃13;

＆＃13;

//get current date
var date = new Date ()

//array with week-day names
var week_days = [
  'Sunday',
  'Monday',
  'Tuesday',
  'Wednesday',
  'Thursday',
  'Friday',
  'Saturday'
];

//your initial variables
var consultations = ['Wednesday', 'Friday'];
var X     = 5;

//loop through X + 1 weeks to find dates and count results
var count = 0
for (var i = 0; i < (X + 1) * 7; i++) {
   
  //get name of date-day
  var week_day = week_days[date.getDay ()];
   
  //check if wanted
  if (consultations.indexOf (week_day) != -1) {
    
    //construct date and output
    var day   = date.getDate ();
    var month = date.getMonth ();
    var year  = date.getFullYear ();
    
    document.write (day + '.' + month + '.' + year);
    document.write ('<br/>');
    
    //increment count
    count++;
    
    //stop if count == X
    if (count == X)
      break;
  
  }

  //increment date
  date.setDate (date.getDate () + 1);
  
}
