I have been struggling with the this output from which hangs my browser. When I run the following code it runs fine.
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
</head>
<body>
<script type="text/javascript">
var input = 5;
for(var i=1;i< 5;i++){
input = i*input;
}
document.write(input);
</script>
</body>
</html>
But this hangs the browser and I have to stop it finally. I cant't find any bug or error in this code.
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
</head>
<body>
<script type="text/javascript">
var input = prompt("Enter the number to get factorial of: ");
var result = input;
for(var i=1;i < input;i++){
result = i * result;
}
document.write(result);
</script>
</body>
</html>

Reset to default 3input = i*input;
increases input
so i < input
is always false
. Try smth like
var input = parseInt(prompt("Enter the number to get factorial of: "));
var result = input;
for(var i=1;i < input;i++){
result = i * result;
}
document.write(result);
<html>
<head>
<title> New Document </title>
<script type="text/javascript">
function fact(num)
{
var x=parseInt(num);
if(x>0)
x=x* fact(x-1);
alert(x);
}</script>
</head>
<body>
<form name="f1">
Enter the Number :<input type="text" length="8" name="txt1"><br>
<input type="button" value="Find factiorial" onclick="fact(txt1.value)">
</form>
</body>
var y = prompt("type number ");
var x = input;
function fact(x) {
if(x==0) {
return 1;
}
return x * fact(x-1);
}
function run(number) {
alert(fact(parseInt(number, 10)));
}
run(x);
