jquery+easeing实现仿flash的载入动画

去年面试过一家做网站的 公司，看了一下他们的案例，看懂一个蛮有意思的 ，一个房地产的官网，是用flash做的。感觉不错。

于是，闲暇之际，简单的jquery 模仿做了一下。下面是我的效果图.脚本也没啥优化，流畅度也没有flash流畅。但是重要的是看到这个flash，想到

如何实现它效果的思路，非常适合新手。

观察上诉，首先左侧是个载入动画，

代码如下:

$('.left').find('ul').delay(90).animate({left:0},700,'easeOutSine',function(){
});

接着 回调函数  调用右侧

代码如下:

$('.left').find('ul').delay(90).animate({left:0},700,'easeOutSine',function(){//'easeOutSine' 引入easing.js 库
   rightImg();
   });
  function rightImg(){
                            $('.right').find('.liImg').first().fadeIn(90).animate({top:0,opacity:1},380,'easeOutSine',function myNext(){// myNext回调自己（递归）
         $(this).parent().next().find('.liImg').fadeIn(90).animate({top:0,opacity:1},420,'easeOutSine',myNext);  
          if($('.right').find('#lastImg').is(":animated")&&$('.right').find('#lastImg').css("top",0)){
        //if($('.right').find('#lastImg').attr("style").indexOf('top:0')){
        //alert('最后一个运动好了');
                 $('.title').animate({ left:0},"slow",function(){//Sky 动画
                  $(".right").find('li').hover(function(){  // 右侧 hover效果
            $(this).find('.liSlideDown').slideDown().show().animate({opacity:0.7},"slow");
         },function(){
         $(this).find('.liSlideDown').stop(true,false).slideUp().hide();
         });//回调结束
        });
          }     
           });
    };

最后的，点击右侧每一个，对应切换左边的上部分dear Sky 部分，观察这里的颜色，利用index 索引的实现。

下面附上源码：  不要忘记 jquery 类库和easeing类库

代码如下:
