über "Fetch" Json Array/Object auswerten

[mat-sche]

Hallo Ulrich,

mit Deinen letzten Codevorschlägen bin ich nicht zurech gekommen. Habe jetzt etwas anderes noch ausprobiert, scheitere daran aber.

Code:

            fetch('http://192.168.188.121/cm?cmnd=status%208').then(function(response) {
                response.text().then(function(text) {
                    JSON.parse(text, function (key, name) {
                        console.log("key");
                        console.log(key);
                        console.log("name");
                        console.log(name);
                        if (key == "Position") { document.getElementById('Value_1').innerHTML = name; }
                       
                    });
                });
            });

Code:

Uncaught (in promise) TypeError: document.getElementById(...) is null
    loadDaten file:///C:/Users/admin/OneDrive/05 - Arduino - Boards - Software/Sketchbook/eigene Progs/29_-_ESP32_NRF24/Html/2024.01.26/rolladen.html:174
    loadDaten file:///C:/Users/admin/OneDrive/05 - Arduino - Boards - Software/Sketchbook/eigene Progs/29_-_ESP32_NRF24/Html/2024.01.26/rolladen.html:169
    promise callback*loadDaten/< file:///C:/Users/admin/OneDrive/05 - Arduino - Boards - Software/Sketchbook/eigene Progs/29_-_ESP32_NRF24/Html/2024.01.26/rolladen.html:168

rolladen.html:174:63

​

für den Programmteil bekommen ich dann diese Fehlermeldung im Entwicklerwerkzeug vom FireFox, warum dies?
Aber!

                        console.log("key");
                        console.log(key);
                        console.log("name");
                        console.log(name);

zeigen mir die richtigen Variablen an, die ich parsen möchte.

Ich habe gerade 3 große ?
