<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>javascript</title>
<script type="text/javascript">
window.onload = writeMassage;
function writeMassage() {
document.getElementById("helloMessage").innerHTML = "hello world";
}
</script>
</head>
<body>
<h1 id="helloMessage">
</h1>
</body>
</html>
1.2 放在标签之间
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
