Passing JScript value to VbScript

I have built an HTA application with JScript language and VbScript. I am trying to pass the value of JScript variable to VbScript, but I am stuck. Can you please help.  Here is the JScript code: (I need to pass the docNum [ ] and rev [ ] values, as there may be multiples.)

<script type="text/javascript">
        
            var room = 1;
            function add_fields() {
                  room++;
                  var objTo = document.getElementById('room_fileds')
                  var divtest = document.createElement("div");
                  divtest.innerHTML = '<div class="content"><span>Document Number: <input type="text" style="width:150px;" name="docNum[]" value="" /></span><span>Rev: <input type="text" style="rev:20px;" name="rev[]" value="" /></div>';
                  
                  objTo.appendChild(divtest)
                  
            }
            
      </script>

<script language="VBScript">
      Option Explicit

      Sub ProcessInfo_OnClick
      
       End Sub
</script>
Thank you
