复制代码 代码如下:
//上下滚动

var textRoll=function(){

$('#notice p:last').css({'height':'0px','opacity': '0'}).insertBefore('#notice p:first').animate({'height':'35px','opacity': '1'}, 'slow', function() { $(this).removeAttr('style');});

                               }

$(function(){

//触发上下文字滚动事件

var roll=setInterval('textRoll()',4000);

$("#notice p").hover(function() {

                                clearInterval(roll);

                             }, function() {

                                 roll = setInterval('textRoll()', 4000)

                            });

            });
