windows-phone-7 - Phonegap WP7 Visual Studio 2010 console.log

Question

Phonegap v1.1.0，如何访问 console.log(string) 的输出？

// provide our own console if it does not exist, huge dev aid!
if(typeof window.console == "undefined")
{
window.console = {log:function(str){window.external.Notify(str);}};
}

// output any errors to console log, created above.
window.onerror=function(e){console.log("Error ::" + e);};

console.log("Installed console ! ");

它正在记录到调试输出窗口

console.log 定义如下

if(typeof window.console == "undefined")
{
    window.console = {
        log:function(str){
            if(navigator.debugConsole){
                navigator.debugConsole.log(str);
            }
            else
            {// In case log messages are received before device ready
                window.external.Notify("Info:" + str);
            }
        }
    };
}

debugConsole.log() 和 window.external.Notify() 的结果是 Debug.WriteLine(msg) 方法调用。所以可能 您可以重定向调试输出 例如，文件并保留此信息，以便稍后调试/查看此信息。不需要连接到 VS 来调试问题，有时它可能非常有帮助，代码示例

TextWriterTraceListener[] listeners = new TextWriterTraceListener[] 
{
    new TextWriterTraceListener("debug.log"),
    new TextWriterTraceListener(Console.Out)
};

Debug.Listeners.AddRange(listeners);
