我正在尝试在HTML/JavaScript应用程序中使用Azure访问控制服务。下面的代码示例将在选择身份提供者进行身份验证后显示令牌：

<!DOCTYPE html>
<html>
<head>
</head>

<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>
    <option value="https://login.live.com/login.srf?wa=wsignin1.0&wtrealm=https%3a%2f%2faccesscontrol.windows.net%2f&wreply=https%3a%2f%2fnamespace.accesscontrol.windows.net%3a443%2fv2%2fwsfederation&wp=MBI_FED_SSL&wctx=pr%3djavascriptnotify%26rm%3duri%253awk%253atest">Windows Live ID</option>

</select> 
<br />
<iframe id="loginFrame" height="200" width="60%" src="" />
<br />
<div id="tokenDiv"></div>
</body>
</html>
以下是需要翻译的内容：

iFrame的内容如下：

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

我遇到了一个错误：

"错误 ACS50021：未注册 windows.external.Notify。"

我该如何在 JavaScript 中注册 notify 事件处理程序？

这是在浏览器中还是在“浏览器控件”中？ - Diodeus - James MacFarlane
这是一个浏览器，可以在手机设备上通过PhoneGap包装的浏览器控件中使用。 - Glaxalg

我认为浏览器不支持这个。我认为只有.NET中的浏览器控件支持它。 - Diodeus - James MacFarlane

你是否已经启用了允许接收消息的URL，类似于这样：
            // 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 XAML 中的 webview 元素。
