Here is log4javascript , which is based on log4j (like log4net).

Answer 2

There are several options.

• log4javascript
• log4js
• blackbirdjs (current favorite)

I liked the lumberjack, but I can not find it at the moment.

I just use Console.log. It logs data in firefox / chrome console.

Answer 4

Alternatively, you can simply implement the REST POST function in the .Net controller, call it via AJAX in your JavaScript code.

Example:

.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!");
