Here is my script in html template

'''function yesnoCheck() {

  if (document.getElementById('yesCheck').checked) {
      siv=document.getElementById('ifYes').style.display = 'block';
      // siv = document.getElementById("yesCheck").value;
      document.getElementById('ifNo').style.display = 'none';
      alert(siv);

  }
  if (document.getElementById('noCheck').checked) {
      document.getElementById('ifYes').style.display = 'none';
      srv=document.getElementById('ifNo').style.display = 'block';
      alert(srv);

           elif request.POST.get('basis2')=='here i need the data from alert(srv)':
         
                    messages.success(request,'Record Saved Successfully...!')
                    return render(request,'stockissue2.html')
           else:
                 messages.info(request,'Material Not Available or Transaction No. wrong')
