弗尤部落格（五）

這一篇中，我實現了，登入和遊客環境下，在首頁中單擊博文標題跳轉到該篇博文，點選博文作者跳轉到該作者部落格首頁，在我的部落格中點選博文標題跳轉到該篇博文。
這些跳轉都是在同一個頁面中實現的，我用母版頁放個人部落格的導航和公告。web頁面放datalist實現博文的，由於不會後臺呼叫datalist中的控制元件，更改不了textbox的大小，我把資料庫更改了，資料庫中有個單獨存放博文摘要的，準備以後實現下自動選取摘要，所以我用了2個datalist來顯示全博文，和詳細博文，寫到這我有個想法，把它換成兩張表是不是可以更好的實現。

我通過3條if判斷登入下和非登入下的情況的。
後面還用之前的方法跳轉到釋出和管理頁面，但是這個在後臺程式碼中要判斷是否登入，沒有登入的話需要登入。
