Windows應用商店 - WinJS：0x800a1391 - JavaScript運行時錯誤：'Windows'未定義

我試圖將谷歌地圖加載到Windows應用商店應用。但是，本機Windows RT功能存在問題：Windows.UI.Popups.MessageDialog。我猜測Windows命名空間超出了範圍，但我現在還不知道如何將此函數放入可以訪問Windows命名空間的範圍中。任何幫助表示讚賞。Windows應用商店 - WinJS：0x800a1391 - JavaScript運行時錯誤：'Windows'未定義

編輯：我越想這件事，就越覺得它與我加載map.html作爲iFrame的源碼有關。因此，map.html的上下文是iFrame，而不是Windows應用商店應用頁面。我猜Windows命名空間不能從iFrame中使用？

從home.html做爲：

  <iframe id="getLocationFrame" src="ms-appx-web:///pages/map/map.html" style="width:600px; height:600px;"></iframe>

例外：

map.js：那就是在網絡隔間執行

     } 
    } 
}); 
})();

碼 - 您的網址說這就是這個代碼是 - 不能訪問WinRT的組件。您將需要使用postMessage等在兩個安全上下文之間進行通信。

多米尼克 - 非常感謝你。 postMessage是關鍵。我會投你一票，但我沒有足夠的分數。 –

我使用此dZone博客的代碼來查找解決方案：http://css.dzone.com/articles/use-winjs-post-message-iframe –

從Map.js：

 function locationFail() { 
      //Can't do this due the the iFrame container 
      //var md = new Windows.UI.Popups.MessageDialog("Could not find you!", "").showAsync; 
      window.parent.postMessage("Could not find you!", "*"); 
     }

從Home.js：

(function() { 
"use strict"; 

WinJS.UI.Pages.define("/pages/home/home.html", { 
    // This function is called whenever a user navigates to this page. It 
    // populates the page elements with the app's data. 
    ready: function (element, options) { 

     window.addEventListener("message", messageReceived, false); 

     function messageReceived(e) { 
      if (e.origin === "ms-appx-web://76ad865e-25cf-485c-bc77-e18186bfd7ee") { 
       var md = new Windows.UI.Popups.MessageDialog(e.data, ""); 
       md.showAsync(); 
      } 
     }; 
    } 
}); 
})();
