在做校园网视频网站的时候,首页有一个导航页面要实现滚动效果,有样例,但代码是在难弄懂,貌似网页设计这块还是只有自己的代码自己懂,索性就仿造别人的效果自己做了一个,大体上还行,看起来还是比较流畅的,不次于原作的幺。
现在先把代码拷贝到这里,以后再逐一简化修改:
实现滚动效果,脚本代码如下:
var all=0; var no=0; var s_width=0; $(document).ready(function(){ all=$('.slide').length; s_width=$('.slide').eq(0).width(); $("#slides").css('width',all*s_width); var contiar=$('.control_links'); for(var i=0;i<all;i++){ contiar.append("<li></li>"); } $('.control_links li').bind('click mouseenter',function(){ var index=$(this).index(); no=index; var no_= no%all; $("#slides").animate({left:(-1*no_*s_width)+'px'},200); $(this).css('background-color','#fff'); $(this).siblings().css('background-color','#333'); }); setInterval(function(){ var no_= no%all; $("#slides").animate({left:(-1*no_*s_width)+'px'},1000); var curr= $('.control_links li').eq(no_); curr.css('background-color','#fff') curr.siblings().css('background-color','#333'); no++; },5000); });
css 代码如下:
img{ border:none; } #daohangpic { width:1000px; margin:0 auto; padding:20px; overflow:hidden; } #daohangpic img { height:380px; width:980px; } #contiar { position:relative; width:980px; height:380px; overflow:hidden; margin:0 auto; } #slides { position:absolute; border:none; } .slide { float:left; width:980px; height:380px; overflow:hidden; border:none; } .control_links{ position:absolute; bottom:10px; right:10px; z-index:200; } .control_links,.control_links li { list-style: none; } .control_links li { float:left; width: 15px; height: 15px; margin-right: 5px; text-align: center; background:#333; border: 1px solid #666; cursor: pointer; opacity:0.5; } .caption { position:absolute; height:50px; width:100%; background-color:#000; bottom:0px; padding-left:20px; padding-top:10px; overflow:hidden; z-index:100; background:url(hdpng.png) no-repeat scroll 0 -1px; } .caption h2 { color: #FFF; font-size: 17px; font-weight: bold; line-height:25px; } .caption p{ display: block; color: #767676; font-size:12px; line-height:15px; }
要实现滚动的区域定义如下:
<div id="daohangpic"> <div id="contiar"> <div id="slides"> <div class="slide"> <a href="http://2.zutvideo.duapp.com/Detail.action?v=687474703A2F2F6D392E6E65746B75752E636F6D2F662F7A792F35356A696567656C61696D656962616E6A69616E676469616E6C692F312E6D6B76" title="格莱美获奖名单揭晓,众大腕颁奖礼现场飙歌" target="_blank"><img src="22080.jpg" alt="Slide 1"> </a> <div class="caption" > <h2>格莱美获奖名单揭</h2> <p>格莱美获奖名单揭晓,众大腕颁奖礼现场飙歌</p> </div> </div> <div class="slide" > <a href="http://2.zutvideo.duapp.com/Detail.action?v=687474703A2F2F6D392E6E65746B75752E636F6D2F662F7A792F6265696A696E67776569736869323031336368756E77616E2F312E6D6B76" title="海内外人气明星齐聚,鸟叔林志玲大跳骑马舞" target="_blank"><img src="22076.jpg" alt="Slide 1"></a> <div class="caption" > <h2>格莱美获奖名单揭</h2> <p>格莱美获奖名单揭晓,众大腕颁奖礼现场飙歌</p> </div> </div> <div class="slide" > <a href="http://2.zutvideo.duapp.com/Detail.action?v=687474703A2F2F6D392E6E65746B75752E636F6D2F662F6C786A2F78696E7869616F616F6A69616E6768752F2A2A2E6D6B76" title="令狐冲、东方不败、任盈盈三段虐恋催人泪下" target="_blank"><img src="22073.jpg" alt="Slide 1"></a> <div class="caption" > <h2>格莱美获奖名单揭</h2> <p>格莱美获奖名单揭晓,众大腕颁奖礼现场飙歌</p> 下 </div> </div> <div class="slide" > <a href="http://2.zutvideo.duapp.com/Detail.action?v=687474703A2F2F6D382E6E65746B75752E636F6D2F672F6C786A2F736F757368656E6A692F2A2A2E6D6B76" title="陈键锋恋上剩女陈紫函,人仙之恋如何收场?" target="_blank"><img src="22050.jpg" alt="Slide 1"></a> <div class="caption" > <h2>格莱美获奖名单揭</h2> <p>格莱美获奖名单揭晓,众大腕颁奖礼现场飙歌</p> 场? </div> </div> <div class="slide" > <a href="http://2.zutvideo.duapp.com/Detail.action?v=687474703A2F2F6D382E6E65746B75752E636F6D2F662F64792F7368616F6E69616E706169646571696875616E7069616F6C69752F312E6D6B76" title="感悟生命之美,沐浴信仰之光" target="_blank"><img src="22014.jpg" alt="Slide 1"></a> <div class="caption" > <h2>格莱美获奖名单揭</h2> <p>格莱美获奖名单揭晓,众大腕颁奖礼现场飙歌</p> </div> </div> </div> <ul class="control_links"> </ul> </div> <div id="back_img"> </div> </div>
