Execute an Ajax request every second [duplicate]

Answer 1

Yes possible using setInterval

1) Keep your ajax within a function.

function fun() {
$.ajax({
            type: 'POST',
            url: 'increment.php',
            data: $(this).serialize(),
            dataType: 'json',
            success: function (data) {
                    $('#hidden').val(data);// first set the value     

            }
    });
}

2) Now using setInterval, you can execute it every second.

var interval = setInterval(fun, 1000);

3) To pause/clear use clearInterval

clearInterval(interval);

4) As other pointed that using setInterval for ajax is not wise, so try using

var interval;
function callAjax() {
  $.ajax({
                type: 'POST',
                url: 'increment.php',
                data: $(this).serialize(),
                dataType: 'json',
                success: function (data) {
                        $('#hidden').val(data);// first set the value 
                        interval = setTimeout(callAjax, 1000);   
                }
        });
}
callAjax();
//clearTimeout(interval);
