[Javascript]橫跨五大瀏覽器-滑鼠滑入動態改變影像

2009/03/06

  這一篇的前身,就是[DW]產品目錄展示,經梅干想了一下,感覺用這名稱應該更貼切,其實該範例是拿DW內建滑入滑出的功能再作點小加工,讓原本滑進滑出變換影像的地方,改顯示在上方的圖片中,由於先前在加工時,忘了作瀏覽器的判斷,以至於在IE7、IE8出現圖片無法顯示的問題,好在有好友男丁格爾的幫忙下,修正了這一個bug,再經由梅干的測試下,該範例無論是在IE6.0、IE7.0、IE8.0、Firefox2、Fireox3、Google Chrome、Safari、Opera都可正常的運作,這一切都要歸功於男丁格爾 大大
