jquery创建的反弹小球动画特效

使用方法

function bounce(bouncingCount, speed) {
      var top = 200;
      var speedRatio = speed/top;
      var heightRatio = top / bouncingCount;
      
      for(var i=1; i<=bouncingCount; i++){
          $('#bouncing-ball').animate({'bottom':top},speed);
          $('#bouncing-ball').animate({'bottom':0},speed/2);
          top = top - (heightRatio);
          speed = speedRatio * top;
	  }
	}

	$( "#bouncing-ball").click(function() {
		bounce(10, 500);
});
