CSS We use CSS to first arrange the products and beautify them, and then set the style of the shopping cart on the right. Please see the code for details:

Copy code The code is as follows:

.box{float:left; width:198px; height:320px; margin-left:5px; border:1px solid #e0e0e0; text-align:center} 

.box p{line-height:20px; padding:4px 4px 10px 4px; text-align:left} 

.box:hover{border:1px solid #f90} 

.box h4{line-height:32px; font-size:14px; color:#f30;font-weight:500} 

.box h4 span{font-size:20px} 

.u-flyer{display: block;width: 50px;height: 50px;border-radius: 50px;position: fixed;z-index: 9999;} 

.m-sidebar{position: fixed;top: 0;right: 0;background: #000;z-index: 2000;width: 35px;height: 100%;font-size: 12px;color: #fff;}

.cart i{width:35px;height:35px;display:block; background:url(car.png) no-repeat;} 

#msg{position:fixed; top:300px; right:35px; z-index:10000; width:1px; height:52px; line-height:52px; font-size:20px; text-align:center; color:#fff; background:#360; display:none}

jQuery

我们要实现的效果是，当用户点击“加入购物车”按钮时，当前商品图片会变成一个缩小的圆球，以按钮为起点，向右侧以抛物线的形式飞出，最后落入页面右侧的购物车里，并提示操作成功。在飞出之前，我们要获取当前商品的图片，然后调用fly插件，之后的抛物线轨迹都是由fly插件完成，我们只需定义起点和终点等参数即可。

复制代码代码如下:

<script> <br>
$(function() { <br>
    var offset = $("#end").offset(); <br>
    $(".addcar").click(function(event){ <br>
        var addcar = $(this); <br>
        var img = addcar.parent().find('img').attr('src'); <br>
        var flyer = $('<img class="u-flyer" src="' img '">'); <br>
        flyer.fly({ <br>
            start: { <br>
                left: event.pageX, //开始位置（必填）#fly元素会被设置成position: fixed <br>
                top: event.pageY //开始位置（必填） <br>
            }, <br>
            end: { <br>
                left: offset.left 10, //结束位置（必填） <br>
                top: offset.top 10, //结束位置（必填） <br>
                width: 0, //结束时宽度 <br>
                height: 0 //结束时高度 <br>
            }, <br>
            onEnd: function(){ //结束回调 <br>
                $("#msg").show().animate({width: '250px'}, 200).fadeOut(1000); //提示信息 <br>
                addcar.css("cursor","default").removeClass('orange').unbind('click'); <br>
                this.destory(); //移除dom <br>
            } <br>
        }); <br>
    }); <br>
}); <br>
</script> 

复制上面的代码，保存并运行即可看到效果，Fly插件的项目官网地址是：https://github.com/amibug/fly，值得一提的是，IE10以下需要添加以下js：
