Please use this as reference.

This is the code I used:

<html>
   <head>
      <title>JavaScript Dates</title>
   </head>
   <body>
      <script>
         var date = new Date();
         document.write("Current Date: " + date );
         var firstDay = new Date(date.getFullYear(), date.getMonth(), 1);
         document.write("<br>"+firstDay);
         var lastDay = new Date(date.getFullYear(), date.getMonth() + 1, 0);
         document.write("<br>"+lastDay);
      </script>
   </body>
</html>

You can edit this code as suitable to your program.

var date = new Date();

var monthStart = Date.UTC(date.getFullYear(), date.getMonth())
monthStart = toIsoDateString(monthStart);
console.log(monthStart);

var nextMonthStart = Date.UTC(date.getFullYear(), date.getMonth() + 1);
nextMonthStart = toIsoDateString(nextMonthStart);
console.log(nextMonthStart);

function toIsoDateString(utcDate) {
  var date = new Date(utcDate);
  return date.toISOString().split('T')[0];
}

date input fields must be in YYYY-MM-DD format. Your code:

var firstDay = new Date(date.getFullYear(), date.getMonth(), 1);

Will give back a string, e.g. Tue Sep 01 2020 00:00:00 GMT-0400 (Eastern Daylight Time), which is not what you want.

You can combine a couple of existing StackOverflow answers to accomplish what you want:

// https://stackoverflow.com/a/23593099/378779
function formatDate(date) {
    var d = new Date(date),
        month = '' + (d.getMonth() + 1),
        day = '' + d.getDate(),
        year = d.getFullYear();

    if (month.length < 2) 
        month = '0' + month;
    if (day.length < 2) 
        day = '0' + day;

    return [year, month, day].join('-');
}

// https://stackoverflow.com/a/13572682/378779
function getFstDayOfMonFnc() {
    var date = new Date();
    return new Date(date.getFullYear(), date.getMonth(), 1)
}

Assuming fdate should be the first of the month and tdate should be today's date:

document.getElementById('fdate').value = formatDate( getFstDayOfMonFnc() );
document.getElementById('tdate').value = formatDate( new Date() );
