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>
