Hi Friend,

Try the following code:

<script>
document.write("<center>"); 
var p=5,q=1;
for(var i=1;i<=5;i++){
for(var k=p; k>=1;k--){
document.write(" ");
}
for(var j=1;j<=i;j++){
document.write(" ");
document.write(j);
}
document.write("<br>");
p--;
}
for(var i=4;i>=1;i--){
    document.write(" ");
for(var k=q; k>=1;k--){
document.write(" ");
}
for(var j=1;j<=i;j++){
document.write(" ");
document.write(j);
}
document.write("<br>");
q++;
}
document.write("</center>"); 
</script>

Thanks
