  • jquery幻灯片、跑马灯,JS文件14KB

    今天公司要对网站首页的幻灯片做优化,原来的老版本是在是太大了,找了下参考资料
    http://www.gcmingati.net/wordpress/wp-content/lab/jquery/imagestrip/imageslide-plugin.html
    发现没有自动播放功能,只能自己动手补充他的jquery.slideviewer.1.2插件实现自动播放功能了
    幻灯片业务需求:
    1、无缝隙横向切换。
    2、切换按钮根据图片的数量动态加载。
    3、每隔n秒自动切换图片,切换按钮也随之切换。
    4、当鼠标停留在图片上时停止播放,鼠标移开继续播放。
    5、能记录用户点击的切换按钮,下一次直接切换到用户点击切换按钮的下一张(如图:现在是2,当我点4了以后下一次的自动切换就到1了)。6、图片要有链接,因为公司的是幻灯片广告。
    话不多说,直接上代码

    ============================js结束===================================

    如何使用:
    放在<head>之间
    <script type="text/javascript">
            $(window).bind("load", function() {
                $("div#mygalone").slideView()
            });
    </script>
