FileUpload上傳後，圖片檔名存進DB #3-- jQuery的 fancyBox特效（展示圖片）－MIS2000 Lab -- ASP.NET專題實務 / WebForm + MVC線上教學影片

本系列有多篇文章，延續上一篇

http://mis2000lab.pixnet.net/blog/post/34543487

之前完成的範例 ListView + FileUpload

做出類似 PChome首頁的效果 -- 棋盤式的資料展示，還有產品圖片

原本的範例，加上jQuery的「fancyBox套件」，讓圖片展示的時候，更有效果。

（您可以到fancyBox的網站上面，自己試玩看看。有Demo可以展示）

即使不懂 jQuery與 JavaScript語法，一樣可以把這個套件給加入 ASP.NET網頁裡面。

但是......

*********************************************************************************************

如果您連「基本的HTML標籤」都不懂，以及

「網站的URL路徑、您放在Web Server硬碟裡面的圖片路徑，兩者寫法略有不同」也不懂的話

*********************************************************************************************

這個範例就進行不下去了

倘若這種基本觀念都不懂，那麼連上面的範例應該也作不出來吧？？

執行成果：

這個範例容易出錯的地方，就是「URL路徑」寫錯了。

不管是「看不見圖片？」、或是「jQuery效果出不來？」.....通常都是這個錯誤引起

因為我不在您身邊，這種設定上的小缺失，您得多實驗幾次

並不難解決。

很多常見的網站效果，都是引用人家現成的 jQuery套件

我也沒學過 jQuery

但我理解一些基本的網頁設定、圖片呈現的路徑...等等，一樣可以在短時間內完成。

很多人都會說：學習 ASP.NET，還是得把 HTML、JavaScript學一下

或許在這個範例裡面，初學者可以瞭解：

在程式碼以外，有哪些「網頁的基礎觀念」您還是懸空、不穩的.....

趕緊找機會補強

因為電影「追殺比爾」的經典台詞說：出來混，總是要還的！

FileUpload_DB這個資料表，請看書本裡面附的資料庫，裡面就有。
或是參閱本文一開始的文章，有教您自己建立此資料表。
