瀏覽網(wǎng)頁(yè)時(shí)不小心會(huì)碰到這樣的一個(gè)網(wǎng)站有幻燈片而且每個(gè)數(shù)字上面都帶有進(jìn)度條閑的無(wú)聊,自己用jquery實(shí)現(xiàn)了一個(gè),因?yàn)橛幸粋€(gè)進(jìn)度條的播放過(guò)程暫不支持ie6，熱愛(ài)特效的你可不要錯(cuò)過(guò)了哈

記得亞馬遜沒(méi)改版之前，首頁(yè)的幻燈片我很喜歡，每個(gè)數(shù)字上面都帶有進(jìn)度條。
閑的無(wú)聊，自己實(shí)現(xiàn)了一個(gè)。用的jquery。
主要用到animate（）方法，
因?yàn)橛幸粋€(gè)進(jìn)度條的播放過(guò)程。
不支持ie6，當(dāng)然，改改還是可以的。
