JavaScript AJAX remote logger [closed]

Answer 1

I recently stumbled upon this presentation of N. Zakas, and implemented the technique explained there. It is quite simple but IMHO very effective

http://www.slideshare.net/nzakas/enterprise-javascript-error-handling-presentation

the idea is to simply issue a call to a server side component (I used a .net handler but it could be a php file as well) which takes some param, log the param values and returns a 1x1 image stream back. What I like the most is that there's no need to involve ajax calls at all.

The code from the presentation is as follows:

    function log(severity, message) {
      var img = new Image();
      img.src = "log.php?sev=" + encodeURIComponent(severity) +
      "&msg=" + encodeURIComponent(message);
    }

    log(1, "something bad happened");
