在JS中如何实现动作

在JS中如何实现动作，举例如下：
例如，跳跃的函数底层源码：
cc.jumpBy = function (duration, position, y, height, jumps) {
return new cc.JumpBy(duration, position, y, height, jumps);
};
example
* var actionBy = cc.jumpBy(2, cc.p(300, 0), 50, 4);
* var actionBy = cc.jumpBy(2, 300, 0, 50, 4);
加载一个图片的代码
加载图片资源this.spritee2 = new cc.Sprite(res.xiaobing);
设置坐标 this.spritee2.attr({
x: size.width / 2,
y: size.height / 2-200
})
图片缩放 this.spritee2.setScale(0.3);
x轴翻转this.spritee2.setScaleX(-0.1);
实现跳跃动作 this.spritee2.runAction(cc.jumpBy(2, cc.p(0, 0), 50, 20))
添加图片到场景中 this.addChild(this.spritee2, 0);
jumpTo:

var actionTo = cc.jumpTo(2, cc.p(300, 300), 50, 4);

var actionTo = cc.jumpTo(2, 300, 300, 50, 4);

cc.jumpTo = function (duration, position, y, height, jumps) {

return new cc.JumpTo(duration, position, y, height, jumps);

};
