Facility Control

Hi Dashboard Team,

I'm wondering if there is documentation floating around on opening/writing external files from a panel? I'm looking at implementing some logging functionality in to some panels we have, ideally I'd like to:

• When a button is pressed, get the current date/time
• Open a file called ddmmyyyy_dashboardLog.log
• Append a line to the end of it with the time, button that's pressed and maybe some other info
• Ideally, if it is a new day, create a new file called ddmmyyyy_dashboardLog.log 

Of course, I wouldn't expect someone to write that whole thing for me but if anyone has some example panels or documentation that can open and write to a file when a button is pressed, I can probably figure out the rest on my own (you may recognise my name from a previous life :-) )

Thanks!

The following page talks about how to get a timestamp from javascript:

https://tecadmin.net/get-current-date-time-javascript/#:~:text=Current%20Time%20in%20JavaScript,%3Ai%3As%E2%80%9D%20format.&text=2-,var%20today%20%3D%20new%20Date()%3B,)%20%2B%20%22%3A%22%20%2B%20today

Once you have the date in the format you want, then you can do something like the following:

  var fileOutput = ogscript.createFileOutput("log3.txt", true);

  var date = new Date();

  var message = date.getHours() +":" + date.getMinutes() + ":" + date.getSeconds() + "  message"

  fileOutput.writeString(message + "\n");

  fileOutput.close();

If you are writing very frequently (like a few times a second), you probably don't want to open and close the file every time.    You could open the file when the panel loads, and then close it when the panel closes.

That's great - thanks Ben!
