h1 tag not working properly in javascript
Question
I am a novice in JavaScript and need some help. I have to display name[i] in an h1 header, so say for instance I write in "John" it would be displayed as
nhoJ
but when I try to put the h1 header around name[i] as it is now, it is displayed like this:
n
h
o
J
Can anyone help me put an h1 header around name[i] and make it display properly?
<html>
<body>
<script>
var namIn = window.prompt("Enter Name, separated by space:" );
var namAr = namIn.split("");
var namArLen = namAr.length;
document.write(namAr + "<br /> Length: " + namArLen + "<br />");
var name = namIn;
for(var i = name.length - 1; i >= 0; i--) {
document.write( "<h1>" + name[i] + "</h1>" );
}
</script>
</body>
</html>

Open the <h1> tag before the loop and close it after the loop:
document.write("<h1>");
for(var i = name.length - 1; i >= 0; i--) {
document.write(name[i]);
}
document.write("</h1>");

alternative instead of the loop:
document.write("<h1>" + name.reverse() + "</h1>");

you are giving h1 in every loop, to solve your problem, do this step
pseudo code:
open h1
loop
name[i]
close h1
thats it

You are creating a new node for each letter, you need to concatenate the characters then write the html node, try something like this:
var newName = "";
for(var i = name.length - 1; i >= 0; i--) {
//reverse.push(name[i]);
newName += name[i];
}
document.write( "<h1>" + newName + "</h1>" );

You are writing too many <h1> tags. Each of these tags write one line in the document.
Hence each character appears on a seperate line.
You should enclose the whole name in a single <h1> tag.
You can do this by:
document.write("<h1>");
for(var i = name.length - 1; i >= 0; i--) {
document.write(name[i]);
}
document.write("</h1>");
