存在空白是補間「開」和「提交」。去掉它。 – Bergi

你把'div's放在'head'裏面了嗎？沒有'body'，你也沒有關閉'html'或'head'標籤？或者這是一個「部分」混合代碼？ –

在＆提交之間有空格。試試這行表單標籤...

有onsubmit事件

<form id="data" name="data" action="connection.php" method="POST" onsubmit="return validate_f()">

之間沒有空格之間存在上&提交空間。試試這個線形態標記......

<form id="data" name="data" action="connection.php" method="POST" onsubmit="return validate_f()">

也

你div's宜<form>標籤內。
關閉</script>標記，在<form>開始之前。
在開始<form>標記之前關閉</head>標記。
關閉html頁面末尾的</html>標籤。

有一個拼寫錯誤 -

document.getElemenetById('password').value 
var username=document.getElemenetById('username').value;

應該

document.getElementById('password').value 
var username=document.getElementById('username').value;

編號：https://developer.mozilla.org/en/DOM/document.getElementById
