var iframe = laya.utils.Browser.window.document.createElement('iframe');
iframe.setAttribute('src', "http://www.layabox.com/";);
iframe.setAttribute('frameborder', 0);
var body = laya.utils.Browser.window.document.getElementsByTagName("body")[0];
body.appendChild(iframe);

//适配处理
var frameWidth = 720 * Laya.stage.clientScaleX;
var frameHeight = 1280 * Laya.stage.clientScaleY;

var styleStr = "position: absolute; left: {0}px; top: {1}px; z-index: 100009;";//laya 的index是100000
var str = styleStr.format((laya.utils.Browser.width - frameWidth) * 0.5, (laya.utils.Browser.height - frameHeight) * 0.5);
this.iframe.setAttribute('width', frameWidth);
this.iframe.setAttribute('height', frameHeight);
this.iframe.setAttribute('style', str);
