Try this:

<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8" />
<title></title>
</head>
<body>
<input type="text" id="textbox1" onkeyup="previewText(this.value)" placeholder="">
<br />
<input type="text" id="textbox2" />
<script>
    function previewText(name) {
        document.getElementById("textbox2").value = name;
    }
</script>
</body>
</html>
