javascript源码：

jquery.fly.min.js 插件源码（可从网上下载）：

!function(a){a.fly=function(b,c){var d={version:"1.0.0",autoPlay:!0,vertex_Rtop:20,speed:1.2,start:{},end:{},onEnd:a.noop},e=this,f=a(b);e.init=function(a){this.setOptions(a),!!this.settings.autoPlay&&this.play()},e.setOptions=function(b){this.settings=a.extend(!0,{},d,b);var c=this.settings,e=c.start,g=c.end;f.css({marginTop:"0px",marginLeft:"0px",position:"fixed"}).appendTo("body"),null!=g.width&&null!=g.height&&a.extend(!0,e,{f.width(),height:f.height()});var h=Math.min(e.top,g.top)-Math.abs(e.left-g.left)/3;h<c.vertex_Rtop&&(h=Math.min(c.vertex_Rtop,Math.min(e.top,g.top)));var i=Math.sqrt(Math.pow(e.top-g.top,2)+Math.pow(e.left-g.left,2)),j=Math.ceil(Math.min(Math.max(Math.log(i)/.05-75,30),100)/c.speed),k=e.top==h?0:-Math.sqrt((g.top-h)/(e.top-h)),l=(k*e.left-g.left)/(k-1),m=g.left==l?0:(g.top-h)/Math.pow(g.left-l,2);a.extend(!0,c,{count:-1,steps:j,vertex_left:l,vertex_top:h,curvature:m})},e.play=function(){this.move()},e.move=function(){var b=this.settings,c=b.start,d=b.count,e=b.steps,g=b.end,h=c.left+(g.left-c.left)*d/e,i=0==b.curvature?c.top+(g.top-c.top)*d/e:b.curvature*Math.pow(h-b.vertex_left,2)+b.vertex_top;if(null!=g.width&&null!=g.height){var j=e/2,k=g.width-(g.width-c.width)*Math.cos(j>d?0:(d-j)/(e-j)*Math.PI/2),l=g.height-(g.height-c.height)*Math.cos(j>d?0:(d-j)/(e-j)*Math.PI/2);f.css({k+"px",height:l+"px","font-size":Math.min(k,l)+"px"})}f.css({left:h+"px",top:i+"px"}),b.count++;var m=window.requestAnimationFrame(a.proxy(this.move,this));d==e&&(window.cancelAnimationFrame(m),b.onEnd.apply(this))},e.destory=function(){f.remove()},e.init(c)},a.fn.fly=function(b){return this.each(function(){void 0==a(this).data("fly")&&a(this).data("fly",new a.fly(this,b))})}}(jQuery);

jquery.min.js （可从网上自行下载,以后不再重复显示）

requestAnimationFrame.js 插件源码，兼容ie（可从网上下载）：

(function () {
  var lastTime = 0;
  var vendors = ['webkit', 'moz'];
  for (var x = 0; x < vendors.length && !window.requestAnimationFrame; ++x) {
    window.requestAnimationFrame = window[vendors[x] + 'RequestAnimationFrame'];
    window.cancelAnimationFrame =
      window[vendors[x] + 'CancelAnimationFrame'] || window[vendors[x] + 'CancelRequestAnimationFrame'];
  }

  if (!window.requestAnimationFrame){
    window.requestAnimationFrame = function (callback, element) {
      var currTime = new Date().getTime();
      var timeToCall = Math.max(0, 16 - (currTime - lastTime));
      var id = window.setTimeout(function () {
          callback(currTime + timeToCall);
        },
        timeToCall);
      lastTime = currTime + timeToCall;
      return id;
    };
  }
  if (!window.cancelAnimationFrame){
    window.cancelAnimationFrame = function (id) {
      clearTimeout(id);
    };
  }
}());

调用插件，页面js：

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