• 网页图片的滚动效果


       有好久没来了,前段时间生病了,所以也没时间添加东西和学习,还有就是先给给我留言和回复的学友道声歉,没能及时给你们解决问题和回答,在这里深感抱歉...好了,别的就不多说了,说说最近的问题吧。

      最近有点忙,以前没接触过网页图片的滚动效果的制作,现在要实现这个了,就临时抱抱佛脚学习了点,现在整理下,以免忘了,多多积累。现在才体会到:书到用时方恨少!好了,别的就不啰嗦了,现在整理了三个模板的滚动效果。

    模板一:js动态图片滚动效果

    非常平滑的JS图片滚动特效代码,无缝循环,速度可自定义,鼠标悬停时停止。它的特点是JS和图片地址分离,这样做你就经易的从数据库动态调用每张图片的地址,方便控制,因此它非常的应用。

    61 -->
    62 </script>
    63 </body>
    64 </html>

     注:var speed = 10;数越小,滚动的速度就越快。

    <div id="demo2"></div>是必须要有的。

    模板二:常用JS图片滚动(无缝、平滑、上下左右滚动)

      本源代码收集了一些常用的网页图片滚动,无缝滚动,效果很平滑,包括上下左右四个方向的滚动,或许你现在用不上这些代码,不过先收藏起来。

    模块三:jQuery控制图片淡入淡出效果

      Query控制图片淡入淡出效果,或许见的多了就不足为奇了,淡入淡出效果不论是在WEB或是WinForm编程中都使用广泛,很经典的一款转场或图片切换特效,在此,把基于jquery实现的图片淡入淡出效果分享给大家,希望对你的编程有帮助。

    20             setInterval(function(){
    21                 if(! $("ul li").eq(n).is(":hidden")){
    22                     $("ul li").eq(n).fadeOut("slow")
    23                 }else{
    24                      $("ul li").eq(n).fadeIn("slow")
    25                 }
    26                 n--;
    27             if(n == 0){
    28                 n = 2;
    29             };
    30             },2000);
    31         });
    32 
    33     </script>
    34 </body>
    35 </html>

    就写着几个吧,其它的如果大家要用,就去网上搜吧,只是帮助自己记住这些而已,当然如果各位觉得可以就可以拿去试试。
