Resetting a setTimeout

Viewed 221878

I have the following:

window.setTimeout(function() {
    window.location.href = 'file.php';
}, 115000);

How can I, via a .click function, reset the counter midway through the countdown?

For NodeJS it's super simple:

const timeout = setTimeout(...);

timeout.refresh();

From the docs:

timeout.refresh()

Sets the timer's start time to the current time, and reschedules the timer to call its callback at the previously specified duration adjusted to the current time. This is useful for refreshing a timer without allocating a new JavaScript object.

But it won't work in JavaScript because in browser setTimeout() returns a number, not an object.

var redirectionDelay;
function startRedirectionDelay(){
    redirectionDelay = setTimeout(redirect, 115000);
}
function resetRedirectionDelay(){
    clearTimeout(redirectionDelay);
}

function redirect(){
    location.href = 'file.php';
}

// in your click >> fire those
resetRedirectionDelay();
startRedirectionDelay();

here is an elaborated example for what's really going on http://jsfiddle.net/ppjrnd2L/

i know this is an old thread but i came up with this today

var timer       = []; //creates a empty array called timer to store timer instances
var afterTimer = function(timerName, interval, callback){
    window.clearTimeout(timer[timerName]); //clear the named timer if exists
    timer[timerName] = window.setTimeout(function(){ //creates a new named timer 
        callback(); //executes your callback code after timer finished
    },interval); //sets the timer timer
}

and you invoke using

afterTimer('<timername>string', <interval in milliseconds>int, function(){
   your code here
});

To reset the timer, you would need to set and clear out the timer variable

$time_out_handle = 0;
window.clearTimeout($time_out_handle);
$time_out_handle = window.setTimeout( function(){---}, 60000 );
