How to get dynamic yyyymm dropdown field in jsp?

[Dormilich]

btw, months in Date go from 0 to 11.

and you can decrement the month by using Date.setMonth()

You need to embed a loop in your year loop to iterate the months.

I created a code which gives me yyyymm dynamically upto current year month..

function dropdown(monthfield, yearfield){
               var monthtext=['01','02','03','04','05','06','07','08','09','10','11','12'];
               var today=new Date()
               var monthfield=document.getElementById(monthfield)
               var yearfield=document.getElementById(yearfield)
               var thisyear=today.getFullYear()
               var thismonth=today.getMonth()
               
               var id = 0;
               for (var y=0; y<=20; y++){
                   for (var m=(monthtext.length-1); m>=0; m--, id++){
                       if(m<=thismonth){
                           yearfield.options[id]=new Option(thisyear+"-"+monthtext[m], thisyear+""+monthtext[m])
                       }else{}
                   }
                   thisyear-=1
                   thismonth = 12;
               }
               yearfield.options[0]=new Option(today.getFullYear(), today.getFullYear(), true, true) //select today's year
           }
