css&js

<script defer></script>可以不影響頁面的載入,前提是無document.write等輸出JS數組用方括弧,C#用大括弧
JS可以用delete刪除物件變數屬性等
var objectA=new Object(a:'屬性1';b:'屬性2')
構造一個函數:new Function(大寫的F,後面最後一個參數為方法體)
arguments.length可得到傳入參數數量
methodName.length可得到定義的參數數量
CSS可以使用多個class
高度自適應問題:
min-height:50px;FF
height:auto !important;FF支援,IE也設定了auto,不過被後面的覆蓋
height:50px;
