網站首頁沒有一點動畫怎麼可以，我以前用過Flash As3做過圖片切換，效果非常不錯，可是麻煩，改變起來麻煩。一直都想自己做個圖片切換效果，總認為比較麻煩，今天自己實踐了一下，其實還比較簡單。不過有個小問題，IE8不兼容模式下 設置有透明效果的div 樣式添加失效了，但是我用谷歌，IE8兼容測試都ok。
反正是給自己記錄的，也不多話了，js沒有與頁面分離，也沒有做出插件。一個網站要不了幾個這種效果，先實現了再說吧。最後的效果還是很高大上的。
頁面+JS代碼
代碼如下:
<script type="text/javascript">
var picCurrent = 1;
var picTotal = 8;
var interval; //自動運行
function picChange(current) {
//停止當前動畫
if ($("#divImg").is(":animated")) { $("#divImg").stop(); }
picCurrent = current;
//為當前選擇的設置樣式
$("#divLink").find("a").removeClass("picselect")
$("#divLink").find("a[title='" + picCurrent + "']").addClass("picselect");
//設置下面的圖片說明
var remark = "<a href=\"images/pic" + picCurrent + ".jpg\">";
switch (picCurrent) {
case 1: remark += " 菊花〔拉丁學名：Dendranthema morifolium（Ramat. ）Tzvel.〕，常用chrysanthemum。菊花是菊科，菊屬多年生草本... "; break;
default: remark += picCurrent + "測試說明"; break;
}
remark += "</a>";
$("#picremark").html(remark);
//運行動畫
$("#divImg").animate({ left: -((picCurrent - 1) * 1000) + "px" }, "1000");
return false;
}
//暫不需使用
function PicPer() {
if (picCurrent > 1) {
picCurrent--;
}
else {
picCurrent = picTotal;
}
picChange(picCurrent);
}
//下一張
function PicNext() {
if (picCurrent == picTotal) {
picCurrent = 1
}
else {
picCurrent++;
}
picChange(picCurrent);
}
//自動切換圖片
function PicRun(functionName) {
picChange(1);
interval = setInterval(PicNext, "3000");
}
$(document).ready(function () {
PicRun();
});
</script>

css的實現
代碼如下:
.picMain
{
margin: auto;
overflow: hidden;
width: 1000px;
height: 400px;
position: relative;
}
.picimg
{
width: 10000px;
height: 400px;
background-color: #000000;
position: absolute;
top: 0px;
}
.picRemark
{
position: absolute;
width: 500px;
height: 50px;
bottom: 0px;
left: 0px;
color: #FFFFFF;
text-indent: 2em;
}
.picRemark a
{
color: #FFFFFF;
text-decoration: none;
}
.picRemark a:hover
{
text-decoration: underline;
}
.picaction
{
position: absolute;
width: 1000px;
height: 50px;
background-color: #000000;
filter: alpha(opacity=50);
-moz-opacity: 0.5;
opacity: 0.5;
overflow: auto;
bottom: 0px;
left: 0px;
text-align: right;
}
.picaction a
{
border: 1px solid #C0C0C0;
width: 30px;
height: 30px;
float: right;
line-height: 30px;
text-decoration: none;
text-align: center;
color: #FFFFFF;
font-weight: bold;
margin-top: 10px;
display: block;
margin-right: 10px;
}
.pic
{
width: 1000px;
height: 400px;
float: left;
}
.picselect
{
