The js file code is as follows: 


/**

 */
var ran = 0;
var range = 0;
var myNumber;
/* Encapsulate methods that generate random numbers */
function sjs(range) {
 ran = Math.random() * range;//[0,range) Random number of 
 var result = parseInt(ran);// Convert Numbers to Integers 
 return result;
}
/* Encapsulate methods for displaying random numbers */
function showRandomNum() {
 var figure = sjs(range);
 $("#first").html(figure);
 var figure2 = sjs(range);
 $("#second").html(figure2);
 var figure3 = sjs(range);
 $("#third").html(figure3);
}
$(function () {
 /* Click the Start button , Events generated */
 $("#start").click(function () {
  
  range = prompt(" Please enter the Random Number Range: ", "168");

  if (range == null)//http://hovertree.com/h/bjaf/3siyd3x7.htm
  {
   return; 
  }

  if (range == 0)
  {
   return;
  }

  if (isNaN(range))//http://hovertree.com/h/bjaf/9vhm2l4f.htm
  {
   alert(" please enter a number ");
   return ;
  }
  /* Start tag disabled, stop tag enabled */
  $("#start")[0].disabled = true;
  $("#stop")[0].disabled = false;
  if (range > 9999 || range<-999)
  {
   // by  Why ask 
   $("#bigDiv div").css("font-size", "60px");//http://hovertree.com/h/bjaf/omgdn4mu.htm
   //return;
  }
  myNumber = setInterval(showRandomNum, 50);// How long to run 1 Seconds, in milliseconds 
 });
 /* Click the End button */
 $("#stop").click(function () {
  /* Start tag enabled, stop tag disabled */
  $("#start")[0].disabled = false;
  $("#stop")[0].disabled = true;
  clearInterval(myNumber);
 });
});
