這是我的網頁
如果我點on sale這個連結 怎麼只顯示sale item = y的資料

------解決方案--------------------
Authorization Required

This server could not verify that you are authorized to access the document requested. Either you supplied the wrong credentials (e.g., bad password), or your browser doesn't understand how to supply the credentials required.

如果是連結,那麼你可以在 連結自己加上傳遞嘛

http://xxxx.com/?item=y

傳遞過去了愛幹啥不就幹啥
------解決方案--------------------
GET參數走進去。
