Phonegap v1.1.0,如何从console.log(字符串)访问输出?

// 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 ! ");

它正在登录到调试输出窗口

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()的结果都是Debug.WriteLine(msg)方法调用。因此可能您可以将调试输出重定向到例如文件,并保留此信息以便稍后调试/查看此信息。调试问题不需要与VS的连接,有时它可能非常有用,代码示例

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

Debug.Listeners.AddRange(listeners);
