接着，作4个商品进行演示，每个商品中有图片、价格、名称以及加入购物车按钮等信息。

jQuery
我们要实现的效果是：当点击“加入购物车”按钮后，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到右侧的购物车里。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左边以及结束后销毁之前的动画。
$(function() {   var offset = $(http://www.shancun.net/skin/default/image/nopic.gif#icon-carthttp://www.shancun.net/skin/default/image/nopic.gif).offset();   $(http://www.shancun.net/skin/default/image/nopic.gif.addcarthttp://www.shancun.net/skin/default/image/nopic.gif).click(function(event) {     var img = $(this).parent().children('img').attr('src'); //获取当前点击图片链接     var flyer = $('<img class=http://www.shancun.net/skin/default/image/nopic.gifflyer-imghttp://www.shancun.net/skin/default/image/nopic.gif src=http://www.shancun.net/skin/default/image/nopic.gif' + img + 'http://www.shancun.net/skin/default/image/nopic.gif>'); //抛物体对象     flyer.fly({       start: {         left: event.pageX,//抛物体起点横坐标         top: event.pageY //抛物体起点纵坐标       },       end: {         left: offset.left + 10,//抛物体终点横坐标         top: offset.top + 10, //抛物体终点纵坐标       },       onEnd: function() {         $(http://www.shancun.net/skin/default/image/nopic.gif#tiphttp://www.shancun.net/skin/default/image/nopic.gif).show().animate({width: '200px'},300).fadeOut(500);////成功加入购物车动画效果         this.destory(); //销毁抛物体       }     });   }); });
以上代码即可完成加入购物车效果，是不是很棒啊！Fly插件官网：https://github.com/amibug/fly，另外兼容IE10以下需要添加以下js文件：
