window.onload = function() { 
 var base = 3; 
 document.getElementById('quantity').onkeyup = function() { 
   if(this.value.length == 0) { 
     document.getElementById('result').innerHTML = ''; 
     return; 
   } 
   var number = parseInt(this.value); 
   if(isNaN(number)) 
     return; 
   var result = number * base;
   result = result.toFixed(2); 
   document.getElementById('result').innerHTML = result; 
   }; 
   document.getElementById('quantity').onkeyup();
};
