网站首页没有一点动画怎么可以，我以前用过Flash As3做过图片切换，效果非常不错，可是麻烦，改变起来麻烦。一直都想自己做个图片切换效果，总认为比较麻烦，今天自己实践了一下，其实还比较简单。不过有个小问题，IE8不兼容模式下 设置有透明效果的div 样式添加失效了，但是我用谷歌，IE8兼容测试都ok。
反正是给自己记录的，也不多话了，js没有与页面分离，也没有做出插件。一个网站要不了几个这种效果，先实现了再说吧。最后的效果还是很高大上的。
页面+JS代码
<script type="text/javascript">
var picCurrent = 1;
var picTotal = 8;
var interval; //自动运行
function picChange(current) {
//停止当前动画
if ($("#divImg").is(":animated")) { $("#divImg").stop(); }
picCurrent = current;
//为当前选择的设置样式
$("#divLink").find("a").removeClass("picselect")
$("#divLink").find("a[title='" + picCurrent + "']").addClass("picselect");
//设置下面的图片说明
var remark = "<a href=\"images/pic" + picCurrent + ".jpg\">";
switch (picCurrent) {
case 1: remark += " 菊花〔拉丁学名：Dendranthema morifolium（Ramat. ）Tzvel.〕，常用chrysanthemum。菊花是菊科，菊属多年生草本... "; break;
default: remark += picCurrent + "测试说明"; break;
}
remark += "</a>";
$("#picremark").html(remark);
//运行动画
$("#divImg").animate({ left: -((picCurrent - 1) * 1000) + "px" }, "1000");
return false;
}
//暂不需使用
function PicPer() {
if (picCurrent > 1) {
picCurrent--;
}
else {
picCurrent = picTotal;
}
picChange(picCurrent);
}
//下一张
function PicNext() {
if (picCurrent == picTotal) {
picCurrent = 1
}
else {
picCurrent++;
}
picChange(picCurrent);
}
//自动切换图片
function PicRun(functionName) {
picChange(1);
interval = setInterval(PicNext, "3000");
}
$(document).ready(function () {
PicRun();
});
