Explanation / Answer
Hi,
Based on the comment am giving answer only for 2 point i.e for random number.
A javascript loads on body load function, then it calculates the random number. it will show the count of random no as alert and in the text box in the html page. PFB. calculateRandom() is javascript function. save the below code as ahtml file and open it in browser, you can see the result. Hope it helps.
<html>
<head>
<script>
function calculateRandom()
{
var sum =0;
var count = 0;
while(sum<=1000)
{
var randomnumber= Math.floor(Math.random()*11);
sum= sum +randomnumber;
count = count +1;
}
alert("no of time random no generated" + count);
document.getElementById("txtCount").value=count;
}
</script>
</head>
<body>Random number count:
<input type="text" id="txtCount"/>
<br/>
</body>
</html>
the line in the above script var randomnumber= Math.floor(Math.random()*11); will generate a no from 0 to 10. You can also give var randomnumber= Math.floor(Math.random()*1001); to take any no from 0 to 1000.
PFB the modified program.
<html>
<head>
<script>
function calculateRandom()
{
var sum =0;
var count = 0;
while(sum<=1000)
{
var randomnumber= Math.floor(Math.random()*1001);
sum= sum +randomnumber;
count = count +1;
}
alert("no of time random no generated" + count);
document.getElementById("txtCount").value=count;
}
</script>
</head>
<body>Random number count:
<input type="text" id="txtCount"/>
<br/>
</body>
</html>
Thanks,
Sri
