Question

На странице есть картинка с кнопками. При нажатии на кнопку - выводиться номер забронированного места (id кнопки в текстовое поле рядом). Как при повторном нажатии на туже кнопку стереть из поля последнее выбранное место?

<script type="text/javascript">
   function Bron(event)
    {
       $id_cnopka = event.target.id;
       document.getElementById('input-bron').value=document.getElementById('input-bron').value+$id_cnopka;
    }
</script>

50 минут назад, klierik сказал:
if (document.getElementById('input-bron').value == '') {
  document.getElementById('input-bron').value = document.getElementById('input-bron').value + $id_cnopka;
} else {
  document.getElementById('input-bron').value = ''
}

 

Тогда действие отменяется при нажатии на любую кнопку, а у меня там 34 кнопки.....
