如何在Javascript中註冊window.external.notify事件處理程序

我試圖在HTML/JavaScript應用程序中使用Azure訪問控制服務。下面的代碼示例會針對選擇的身份提供商的認證後顯示令牌：如何在Javascript中註冊window.external.notify事件處理程序

<!DOCTYPE html>

<body> 
<script type="text/javascript"> 
    function handleData (data){ 

     document.getElementById('tokenDiv').innerHTML = "Token = " + data; 
    } 
    function chooseIdentityProvider (url){ 

     document.getElementById('loginFrame').src = url;    
    } 
    // HOW TO register notify event handler?  
    window.external.notify = handleData;   
</script> 
<select name="AvailableProviders" onchange="if (this.selectedIndex) chooseIdentityProvider (this.value)"> 
    <option value="-1">Select Identity Provider</option>

</select> 
<br /> 
<iframe id="loginFrame" height="200" width="60%" src="" /> 
<br /> 
<div id="tokenDiv"></div> 
</body> 
</html>

iframe的內容是這樣的：

<script type="text/javascript"> 
    try{ 
     window.external.notify(...token...); 
    } 
    catch(err){ 
     alert("Error ACS50021: windows.external.Notify is not registered."); 
    } 
    </script>

我得到錯誤：「錯誤ACS50021：窗口。外部。通知未註冊。「

這是在瀏覽器或「瀏覽器控制」中？ – 2012-02-14 20:57:20

這是瀏覽器，並且可以用於通過手機封裝的移動設備上的瀏覽器控件 – Glaxalg 2012-02-14 22:35:59

我不認爲瀏覽器支持此功能。我認爲這只是.NET中的瀏覽器控件。 – 2012-02-15 14:18:47

你有沒有啓用允許的URL收到消息，是這樣的：

  // code needed -> allowed parameter to check all URL 
     var unloadFunc = "(function(){ function navigating(){ window.external.notify('%%' + location.href);} window.onbeforeunload=navigating;return location.href;})();"; 
     var host = wv.InvokeScript("eval", new string[] { unloadFunc }); 
     wv.AllowedScriptNotifyUris = new[] { new Uri(host) };

WV是在XAML

web視圖元素，如果你正在使用的iframe你將需要使用postMessage API。 http://msdn.microsoft.com/en-us/library/ie/cc197015(v=vs.85).aspx

window.external.notify是一個只能在XAML WebView控件或HTML x-ms-webview控件中工作的API。
