:0:too much recursion错误

还是有这个错误，和缩放无关，回调也没打日志，直接报的那个错误
cc.loader.load(picUrls[i].pic,function (err, texture) {
console.log('pic url:',picUrls[i].pic);
console.log('err:',err);
if(texture!=null){
console.log('ad:',texture,texture.width,texture.height);
picUrls[i]['texture']=texture;
var frame=new cc.SpriteFrame(texture);
sprite.spriteFrame=frame;
var scalex=300/texture.width;
var scaley=50/texture.height;
console.log('scalex:',scalex,'scaley:',scaley);
//sprite.node.scaleX=scalex;
//sprite.node.scaleY=scaley;
}
})
