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(); }); </script>
