Question

I am using javascript setInterval() to check user idle time and show a popup alert before automatic logout. But it does not work for multiple tabs (working fine for single t

Answer 1

Thank you guys, I got the solution for this.

I used a localStorage value with current time stored in it. If there is no value exists in localStorage["currentTime"], stored current time in localStorage .

var currentTime         = new Date();

if ( !(localStorage.getItem("currentTime")) || (localStorage.getItem("currentTime") == "") )
{
        idleTime        = 0;
        setTimeout(function() { localStorage.setItem("currentTime", currentTime)},5000); // current time is set to localStorage after  seconds (it is for setting in multiple tabs)
} 

All calculations to show timeout popup is done using localStorage.getItem("currentTime") value.

Then I set localStorage["currentTime"] to null if user is not idle (when user clicks somewhere)

$(this).click(function (e) 
{
    $('#timeoutWindow').modal('hide');
    localStorage.setItem("currentTime", "");
    idleTime = 0;
});
