cocos2d-x javascript如何用plist创建动画

Cocos2d-x
#1

新人刚开始学习cocos2d-x javascript ，请问如何用plist创建动画？

#2 
        WinSize = cc.Director.getInstance().getWinSize();
        cc.SpriteFrameCache.getInstance().addSpriteFrames(s_loading1_plist);
        var loadingRole = cc.Sprite.createWithSpriteFrameName("loading1_10.png");
        loadingRole.setPosition(cc.p(WinSize.width / 2, WinSize.height / 2));
        this.addChild(loadingRole, 0);
        var myarray = ];            for (var i = 0; i < 10; i++) {
            var t = i + 10;
            var s = t.toString();
            var frame = cc.SpriteFrameCache.getInstance().getSpriteFrame( "loading1_" + s + ".png" );
            myarray.push(frame);
            cc.log(myarray.length);
        }
        var anmation = cc.Animation.create(myarray, 0.1, 1);

这是我的代码，到var anmation = cc.Animation.create(myarray, 0.1, 1);时会报错；

这是报错内容：
Assertion failed!

Program: …cocos2d-2.1rc0-x-2.1.2Debug.win32libcocos2d.dll
File: d:cocos2dxcocos2d-2.1rc0-x-2.1.2co…ccanimation.cpp
Line: 144

Expression: dynamic_cast<CCAnimationFrame*>(*arr)

For information on how your program can cause an assertion
failure, see the Visual C++ documentation on asserts
