Alternatively you can just implement a REST POST Function in an .Net Controller an call it via AJAX in your JavaScript Code.

Example given:

.Net Controller Funktion

    private static readonly ILog log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

    // POST: LogFromJavaScript
    [AllowAnonymous]
    [HttpPost]
    [ValidateInput(false)]
    public void LogFromJavaScript(String errorMessage)
    {
        log.Error("Log from JavaScript: " + errorMessage);
    }

Java Script AJAX Implementation

function LogFromJavaScript(errorMessage) {
    $.ajax(
    {
        url: window.urlLogError,
        type: "POST",
        dataType: "text",
        cache: false,
        data: {
             errorMessage: errorMessage
        }
    });
}

And then use it in your JavaScript Code

window.LogFromJavaScript("Hello JS Log!");

There are several options.

I liked lumberjack, but can't locate it at the moment.

There's a log4javascript, which is based on log4j (as is log4net).

I simply use Console.log. It logs data to the firefox/chrome console.
