广告切换效果(缓动切换)

复制代码 代码如下:

$(document).ready(function(){
    var MyTime=false;    //定时器                
    var piclist=$("#piclist"); //图片列表
    var num=piclist.find("li").length; //自动检测图片广告个数
    var picnum=$("#picnum");
    var index=0; //起始序列
    var width=388; //广告宽度
    var movetime=600; //单次动画所用时间
    var speed=3000; //切换时间间隔    

    
//标记当前
function cur(ele){        
        ele=$(ele)? $(ele):ele;
        ele.addClass("cur").siblings().removeClass("cur");    
        }
function int(){
    piclist.css({"width":width*num+"px"});
    var nums="";
    for(i=0; i<num; i++){        
        if(i<9){            
            nums+="<span>"+0+(i+1)+"<\/span>";
            } else{                    
                nums+="<span>"+(i+1)+"<\/span>";
                }
        }
    picnum.html(nums);
    cur(picnum.find("span").eq(index));
    }
//初始化执行    
int();        

$(picnum.find("span")).mouseover(function(){
    index=$("#picnum span").index($(this)[0]);    
    //if(!piclist.is(":animated")){
        move();        
        //}        
    })

            
var move=function move(){
    piclist.animate({"left":-width*index+"px"},{queue:false,duration:movetime, easing: "easeOutQuart"});
    cur(picnum.find("span").eq(index));
    }    

    $('div.flsad').hover(function(){
             if(MyTime){
                 clearInterval(MyTime);
             }
     },function(){
             MyTime = setInterval(function(){
             move()
                index++;
                if(index==num){index=0;}
             } , speed);
     });
     //自动开始
     MyTime = setInterval(function(){
        move();
        index++;
        if(index==num){index=0;}
     } , speed);    
})
