Need to notify users that they would be logged out

Recommended Posts



Was hoping someone can help me here.


I know that the DataPage timeout  is a security feature of Caspio to prevent unauthorized access of other people when the user is AFK.

However, I would want my users to be notified if they will be logged out after a couple of minutes for them to save their work.


A support person suggested that I extend my login timeout in the Authentications. But I don't use one.

Finally,  he/she told me that it is possible to notify my users that they will be timed-out with the use of JavaScript.

Hello @TroubleShooter,


You may try to add this snippet of JavaScript Code in the footer (source) of your DataPage. Just read through the inline comments (//).


Works for me in all DataPages where you can insert a Footer.

// Edit the values here to your liking
var message = 'You will be logged out after [x] minutes. Please save your work to prevent input loss.';
var hour = 0;
var min = 0;
var sec = 3;
// It is not necessary to edit things beyond this point
//Do not edit the Hour, Min, Sec here. They are used as a Default Value!
setTimeout(function(hour=0, min=0, sec=1) {
  //Do stuff here
  //Get Time Reference
  var timeRef = new Date().toLocaleTimeString('en-US');
  //Show the timeRef and the Message
  alert('[' + timeRef + '] ' + message); 
  //You can also do other stuff below such as (displaying a div, auto-press the save button, etc...)
}, (hour*1000*60*60 + min*1000*60 + sec*1000) );
