Contoh dalam artikel ini menerangkan cara jQuery melaksanakan kembali ke kesan teratas. Kongsikan dengan semua orang untuk rujukan anda. Kaedah pelaksanaan khusus adalah seperti berikut:
1. Pertama ialah gaya CSS:
/*updown*/ #shangxia{position:fixed;top:83%;right:42%;margin-right:-543px;display:block;_display:none} #shang,#comt,#xia{background:url(../images/sprite.png) no-repeat;position:relative;cursor:pointer;height:25px;width:29px;margin:10px 0 0} #shang{background-position:0 -308px}#comt{background-position:0 -338px;height:32px} #xia{background-position:0 -376px} #comt:hover{background-position:-31px -338px}#shang:hover{background-position:-31px -308px} #xia:hover{background-position:-31px -376px}
2. Seterusnya ialah kod jquery: (untuk memperkenalkan perpustakaan teras jQuery)
