使用WindowDialog弹出页面，弹出页消失不了

fdsczk

主页布局代码如下：
<?xml version="1.0" encoding="UTF-8"?>
<div xmlns="http://www.w3.org/1999/xhtml" xid="window" class="window" component="$UI/system/components/justep/window/window" design="device:m;">  
  <div component="$UI/system/components/justep/model/model" xid="model" style="height:auto;left:390px;top:161px;" onLoad="modelLoad"/>  
  <span component="$UI/system/components/justep/windowDialog/windowDialog"
  src="mainActivity.w" title="对话框" showTitle="false" xid="xxwindowDialog"/>
  <div component="$UI/system/components/justep/contents/contents" class="x-contents x-full" active="0" xid="pages" swipe="false" >
  </div>
</div>
主页js文件：
Model.prototype.modelLoad = function(event){
                this.comp("xxwindowDialog").open();
        };
然后再弹出页的onload里让弹出页消失，
弹出页布局：
<?xml version="1.0" encoding="UTF-8"?>
<div xmlns="http://www.w3.org/1999/xhtml" xid="window" class="window" component="$UI/system/components/justep/window/window" design="device:m;">  
  <div component="$UI/system/components/justep/model/model" xid="model" onLoad="modelLoad"/>
<img src="$UI/MobileWebServiceUI/keepcar/common/icon/display_loading_img/bg_index.png" alt="ss" xid="image1"></img></div>
弹出页js：
  Model.prototype.modelLoad = function(event){
        setTimeout("this.close();",5000);
        };
结果五秒后弹出页不消失，提示“scripts my close only the windows that were opened by it”
求教怎样解决，感谢

var me = this;
setTimeout(function(){
me.close();
},5000);回调中this 用法注意
