我正在Firefox上调试Silverlight2。我在firebug中发现一个未处理的错误：

指向Silverlight.js第26行

control = new ActiveXObject('AgControl.AgControl');
我的html是

为什么它不能在JS中处理并显示在errorLocation中？
也很抱歉我的格式设置很糟糕。

想出了一个解决方案
转到App.xaml.cs文件并重新处理了未处理的_异常函数

有了这个，再加上一点对这个JS的称呼，一切都很简单

private void Application_UnhandledException(object sender, ApplicationUnhandledExceptionEventArgs e)
    {
        // If the app is running outside of the debugger then report the exception using
        // the browser's exception mechanism. On IE this will display it a yellow alert 
        // icon in the status bar and Firefox will display a script error.


        // NOTE: This will allow the application to continue running after an exception has been thrown
        // but not handled. 
        // For production applications this error handling should be replaced with something that will 
        // report the error to the website and stop the application.
        e.Handled = true;

        try
        {
            ThrowRightError(e.ExceptionObject);
            //System.Windows.Browser.HtmlPage.Window.Eval("throw new Error(\"Unhandled Error in Silverlight  a 2 Application " + errorMsg + "\");");
        }
        catch
        {
        }

    }
    private void ReportErrorToDOM(ApplicationUnhandledExceptionEventArgs e)
    {
        try
        {
            ThrowRightError(e.ExceptionObject);
            //System.Windows.Browser.HtmlPage.Window.Eval("throw new Error(\"Unhandled Error in Silverlight 2 Application " + errorMsg + "\");");
        }
        catch (Exception)
        {
        }
    }

    private void ThrowRightError(Exception e)
    {
        string errorMsg = "";
        var exLayer = -1;
        //errorMsg += String.Format("<br>Layer {0}<hr>", exLayer);
        Exception ex2 = e;
        while (ex2 != null)
        {
            errorMsg += "Message : <br />" + ex2.Message + "<br />Data :<br />" + ex2.Data + "<br />StackTrace :<br />" + ex2.StackTrace;
            exLayer++;
            errorMsg += String.Format("<br>Layer {0}<hr>", exLayer);
            ex2 = ex2.InnerException;
        }
        errorMsg = errorMsg.Replace('"', '\'').Replace("\r\n", @"<br />");

        HtmlPage.Window.CreateInstance("foo2", new[] { errorMsg });
    }
我还弄清楚了最初的错误是什么

ClientIdTextBlock.SetBinding(TextBox.TextProperty, ClientIdBinding);
文本块的文本框绑定…愚蠢的错误。

它在IE和/或从Visual Studio或Blend运行时有效吗？ 
function foo2(theAlert) {
     $("#errorLocation").html(theAlert);
}

ClientIdTextBlock.SetBinding(TextBox.TextProperty, ClientIdBinding);
