[导读] jQuery实现列表自动滚动循环滚动展示新闻,鼠标悬停时停止滚动并提示,离开后,继续滚动,实现的代码如下,需要的朋友可以看看...
需要在页面中一个小的区域循环滚动展示新闻(公告、活动、图片等等),并且,鼠标悬停时停止滚动并提示,离开后,继续滚动。 效果图: html: 复制代码 代码如下: <div id="news"> <ul> <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title="aaaaaaaaaaaaaaa">aaaaaaaaaaaaaaa</a></li> <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title="bbbbbbbbbbbbbbb">bbbbbbbbbbbbbbb</a></li> <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title="ccccccccccccccc">ccccccccccccccc</a></li> <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title="ddddddddddddddd">ddddddddddddddd</a></li> <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title="eeeeeeeeeeeeeee">eeeeeeeeeeeeeee</a></li> <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title="fffffffffffffff">fffffffffffffff</a></li> <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title="ggggggggggggggg">ggggggggggggggg</a></li> </ul> </div> css: 复制代码 代码如下: ui,li { list-style: none; } #news{ height: 75px; overflow: hidden; } 关键是js文件: 复制代码 代码如下: $(function() { var $this = $("#news"); var scrollTimer; $this.hover(function() { clearInterval(scrollTimer); }, function() { scrollTimer = setInterval(function() { scrollNews($this); }, 2000); }).trigger("mouseleave"); function scrollNews(obj) { 主要就是对hover、setInterval、clearInterval、animate这些方法以及marginTop属性(marginLeft、top、left等等)的理解和运用,需要注意的是,如果不加.trigger("mouseleave"),在网页初始化的时候列表不会滚动,还有appendTo能直接移动元素,就这些了。 |
