Hello I am trying to do a simple program. But the basics of this program must have buttons like a calculator. So I was just testing my array and for loop and I can't seem to get anything to show up whatsoever I've tried document.write, alert and so forth. and I can't seem to find my error in the for loop or any syntactic errors. Or even logic errors. I have looked in several books that I have and it seems that everything that I have is fine according to my books. So idk what I am missing, or doing wrong. Could someone please help me figure this out. Here is my code:
<html>
<head>
<meta charset = "utf-8">
<title>Flash Math</title>
<script type = "text/javascript">
var button = new Array (9);
var buttonString = "";
for (var i = 0; i < button.lentgh; i++)
{
buttonString += button[i] + " ";
document.write("Calculator" + i);
}
</script>
</head>
