there's syntax error, due wrong closing block.
that is, } token @ line 15 wrong (you have remove it).
to avoid kind of erros, helpful being strict on code indentation, aditionally improves code readability. way, fixed , formatted code similar this:
<html> <body> <script type="text/javascript"> var fib1=0,fib2=1,fib=0; var num = prompt("enter number"); if(num!=null && num>0) { document.write("<h1>" +num+ "fib <br/></h1>"); if(num == 1) document.write("<h1>" +fib1+ "</h1>"); else document.write("<h1>" +fib1+ " " +fib2+ "</h1>"); for(i=3;i<=num;i++) { fib=fib1+fib2; document.write("<h1>" +fib+ "</h1>"); fib1=fib2; fib2=fib; } } else alert("no proper input"); </script> </body> </html>
