今天把博客的公告栏做了一个小效果,如果有2条公告或以上就有个滚动效果,实例请移目前端组公告栏。在此感谢Newton同学的耐心指导,不多说了,上代码!或者你可以直接前往DEMO看实例
jQuery代码
- //第二版:Newton改造
- (function (win){
- var callboarTimer;
- var callboard = $('#callboard');
- var callboardUl = callboard.find('ul');
- var callboardLi = callboard.find('li');
- var liLen = callboard.find('li').length;
- var initHeight = callboardLi.first().outerHeight(true);
- win.autoAnimation = function (){
- if (liLen <= 1) return;
- var self = arguments.callee;
- var callboardLiFirst = callboard.find('li').first();
- callboardLiFirst.animate({
- marginTop:-initHeight
- }, 500, function (){
- clearTimeout(callboarTimer);
- callboardLiFirst.appendTo(callboardUl).css({marginTop:0});
- callboarTimer = setTimeout(self, 5000);
- });
- }
- callboard.mouseenter(
- function (){
- clearTimeout(callboarTimer);
- }).mouseleave(function (){
- callboarTimer = setTimeout(win.autoAnimation, 5000);
- });
- }(window));
- setTimeout(window.autoAnimation, 5000);
HTML代码:
- <div id="callboard">
- <ul>
- <li>
- <a href="http://www.qianduanzu.com/2012042036.html">公告:前端组主题正在整理中..有需要用的朋友请留个言,以方便及时通知!</a>
- </li>
- <li>
- <span style="color:red;">公告:前端组上线一个月零八天,PR升为3,BD权重1</span>
- </li>
- </ul>
CSS代码:(可根据需求另设)
- #callboard { height:24px; line-height:24px; overflow:hidden;}
- #callboard ul { padding:0;}
- #callboard li { padding:0;}
