To activate the traces coming from EWC, you have to include a new JavaScript library named "logging.js" in your HTML page.

<script src="sconnect_uc.js"></script>
<script src="pcsc_uc.js"></script>

<script src="logging.js"></script>
  
<script src="enex.js"></script>

EWC register each operation performed.

In your JavaScrip file, you have to call the getTrackingInformation function to retrieve the tracking logs. The function returns an array of Objects containing for each a category (debug, info, warning, error ), a time-stamp and an associated tracking item message.

function displayTracking( ) {
  
  var e = document.getElementById( "logs" );
  e.innerHTML = "";

  var log = enex.getTrackingInformation( );
  
  if ( log ) {

    // Format the record for screen display
    var r = "";
    for( i = 0 ; i < log.length ; ++i ) {
      
      switch( log[ i ].Category ) {
        
        case "Debug":
          r = "Debug - ";
          break;
          
        case "Info":
          r = "Info - ";
          break;
          
        case "Warning":
          r = "Warning - ";
         break;
        
        case "Error":
          r = "Error - ";
          break;
        
        default:
          r = "Unknown - ";
          break;
      }

      r += log[ i ].TimeStamp;
      r += " - ";
      r += log[ i ].Message;

      e.innerHTML += r;
    }
  }
}
