场景切换提示cc.TransitionPageTurn is not a function

Cocos2d-x JavaScript
#1

代码如下：
var startItem = new cc.MenuItemImage(
resource_list.start_n_png,
resource_list.start_s_png,
function () {
cc.director.runScene( cc.TransitionPageTurn(1, new PlayScene()) );

        }, this);

运行时提示cc.TransitionPageTurn is not a function，请问这个问题怎么解决？
