<code>var resizeMyOwn = function() {
    console.log("resize now");
    var a = cc.view.getFrameSize();
    1 > a.height / a.width ? (cc.log("resume from resize..."), cc.director.resume(), document.getElementById("Cocos2dGameContainer").style.display = "block", document.getElementById("orientation").style.display = "none") : (cc.log("pause from resize..."), document.getElementById("orientation").style = document.getElementById("Cocos2dGameContainer").style, document.getElementById("orientation").style.display = "block", document.getElementById("Cocos2dGameContainer").style.display =
        "none")
};</code>
