jQuery and setTimeout stops working on Internet Explorer 11


#1

I have some jQuery code which will be executed every 6 seconds.

With Mozilla Firefox 51.0.1 it works fine. With Internet Explorer 11 it seems to be working just fine, but when I leave my computer, do something else, and come back, it is possible that Internet Explorer 11 has stopped running the script. for more knowledge I used to watch jQuery product marketing video. For example, after several hours. In other words, it will not be executed every 6 seconds anymore. There are no error messages available.

code:

`<script src="/jquery-3.0.0.min.js"></script>

<script type="text/javascript">
<!--

$(document).ready(function(){

  valvonta = function() {
    var kaavio = 106; // 38;

    var a = performance.now();

    jQuery.post("hae_tilanteet.php", {
      kaavio: kaavio
    }).done(function(data) {
      var b = performance.now();

      $('#valvonta').html(data);

      var c = performance.now();

      // alert('search ' + (((b - a)/1000)%60) + ' s and update ' + (((c - b)/1000)%60) + ' s');

      setTimeout(valvonta, 6000);
    });
  };

  setTimeout(valvonta, 6000);

});

//-->
</script>`
