Logging JScript Errors to windows event log

Writing Jscript for Dynamics CRM is a tough task, there were no errors is the data is in proper format, but somtimes i wish to log all those information & exception in some place to review/analyse. But since Jscript is not meant for this. Still there is something that you can do with Windows Event Logger. Here is a small script that uses activeXObject to write the log to eventviewer. Later you can view the log by running "eventvwer" in the cmd prompt.

Here is the script

// Creates a log object 
Log.prototype = {
    // adds functions to it
    Err:function(Error){
        var WshShell = new ActiveXObject("WScript.shell");
        WshShell.LogEvent(1,Error);
    },
    Success:function(Message){
        var WshShell = new ActiveXObject("WScript.shell");
        WshShell.LogEvent(0,Message);
    },
    Warn:function(Warning){
        var WshShell = new ActiveXObject("WScript.shell");
        WshShell.LogEvent(2,Message);
    },
    Info:function(Information){
        var WshShell = new ActiveXObject("WScript.shell");
        WshShell.LogEvent(4,Information);
    },
    AuditSuccess:function(Message){
        var WshShell = new ActiveXObject("WScript.shell");
        WshShell.LogEvent(8,Message);
    },
    AuditFailure:function(Message){
        var WshShell = new ActiveXObject("WScript.shell");
        WshShell.LogEvent(16,Message);
    }
}

// Calling the log to write error
Log.Err("error in script");
