Question

$.getJSON правильно выполняется, но теги js не обновляются (решено)

Я не эксперт по JS и хотел бы получить любую поддержку. Я пытаюсь обновлять многие теги (1 в коде здесь внизу) каждые 1000 мс.

Я использую этот код:

<script type="text/javascript">
        $(document).ready(function(){
            $.ajaxSetup({ cache: false });
                setInterval(function() {
                $.getJSON("Maj_Tag_PLC.htm", function(data){
                    $('#watchdog').text(data.watchdog);
                    });
                },1000);
        });

Кажется, что этот getjson работает, потому что я вижу "ответ" на вкладке сети (хром) с обновленными тегами:

{ "watchdog" : 29304, "count" : 29304, "Etat_Lampe_Plafond_Cuisine" : 0, "Etat_Lampe_Tetes_Murs_Cuisine" : 0, "Etat_Lampe_Plafond_Salon_Rue" : 0, "Etat_Lampe_Plafond_Salon_Jardin" : 0, "Etat_Lampe_Tetes_Murs_Salon" : 0, "Temps_Restant_Plafond_Cuisine" : T#0MS, "Temps_Restant_Tetes_Murs_Cuisine" : T#0MS, "Temps_Restant_Plafond_Salon_Rue" : T#0MS, "Temps_Restant_Plafond_Salon_Jardin" : T#0MS, "Temps_Restant_Tetes_Murs_Salon" : T#0MS, "Temps_Total_Plafond_Cuisine" : T#0MS, "Temps_Total_Tetes_Murs_Cuisine" : T#0MS, "Temps_Total_Plafond_Salon_Rue" : T#0MS, "Temps_Total_Plafond_Salon_Jardin" : T#0MS, "Temps_Total_Tetes_Murs_Salon" : T#0MS }

-> это соответствует моему "Maj_Tag_PLC.htm"

Большой!

Но, похоже, следующая часть моего кода никогда не выполняется:

$('#watchdog').text(data.watchdog)

Я говорю это, потому что поле сторожевого таймера никогда не обновляется, и скрипт никогда не останавливается на этой строке, если я поставлю на него точку останова.

Есть идеи, что случилось?

Спасибо за помощь

(Я читал некоторую информацию об "асинхронном запросе" и о том факте, что эта часть "скрипта может быть выполнена до того, как может быть возвращен ответ", но я действительно не понимаю, что это означает и как его решить.)

Я думаю, вам нужно декодировать данные в формате json следующим образом:

$.getJSON("Maj_Tag_PLC.htm", function(data){
  let result = JSON.parse(data);
  $('#watchdog').text(result.watchdog);
});
