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p 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

代码如下:


<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 ($("#pimg").is(":animated")) { $("#pimg").stop(); }
            piccurrent = current;
            //为当前选择的设置样式
            $("#plink").find("a").removeclass("picselect")
            $("#plink").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
            $("#pimg").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>


 

代码如下:

 css的实现

代码如下:


.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
{
    background-color: #919191;
}
