gan ane kan punya JS kek gini , fungsinya buat nampilin beberapa element form yg tadinya di hidden pake CSS

function toggle4(showHideDiv) {

  
       var ele = document.getElementById(showHideDiv + counter);
    //var x = document.forms["form1"]["cuset"+counter+1];
    
       if(ele.style.display == "block") {
    
              ele.style.display = "none";
  
     if (counter >= 0){
    
     counter--;
     
     }
     
     
       }

       else if(ele.style.display == "none"){
    
             ele.style.display = "block";    
      
       }
    
 
       if(counter == numBoxes) {
                document.getElementById("toggleButton").style.display = "none";
       }
    else{
    document.getElementById("toggleButton").style.display = "inline";
    }
    
 if(counter == 0) {
                document.getElementById("toggleButtonRemove").style.display = "none";
       }
    else{
    document.getElementById("toggleButtonRemove").style.display = "inline";
    }

  </div>
        </td>
        <td>
        </td>
  
    </tr> 


trs 2 tombol ,
tombol add buat menampilkan (onclick="counter++; toggle4('box');")
tombol remove buat menghide (onclick="toggle4('box');")

<input id="toggleButton" type="button" value="ADD">
  <input id="toggleButtonRemove" type="button" value="REMOVE"> 


itu kan tiap di klik tombol add
maka muncul element diantara
<div id="box[nomor]" style="display: none;"> 

</div> 


trs kalo ane mau nya pas klik tombol remove , input ini clear , soalnya nanti berpengaruh di post ke database nya , soalnya waktu di hide dia ga sekalian clear , jd nya ikut ke posting ke database

<input name="cuset3" id="cuset3" type="radio" value="cuci dan setrika" /> Cuci + Setrika
  
  <input name="cuset3" id="cuset3" type="radio" value="setrika" /> Setrika 


ane udh tambahin

document.getElementById("cuset"+counter+1).checked=false;

buat clear element baris terakhir yg di hide

jd gini JS nya ,

if(ele.style.display == "block") {
    
              ele.style.display = "none";
    document.getElementById("cuset"+counter+1).checked=false;
  
     if (counter >= 0){
         counter--;
     
     } 


malah fungsi nya jd ada yg error tombol remove kdg malah jd add
mohon bantuanya gan , atau agan punya metode laen buat clear ?

thanks in advance
