Help with loop


Recommended Posts

Hello! I'm very new with Javascript and I'm working to modify some demo files that I found. 

I'm trying to display JSON data in a div on an HTML page. It's working, but only for two pieces of data:

The web page:


The script:

            .then(function (response) {
                return response.json();
            .then(function (data) {
            .catch(function (err) {
                console.log('error: ' + err);
        function appendData(data) {
            var mainContainer = document.getElementById("myData");
            for (var i = 0; i < data.length; i++) {
                var div = document.createElement("div");
                div.innerHTML = 'EOS IP ' + data[i].eosIP + "<br>" + "EOS OSC Tx Port " + data[i].eosTxPort; + "<br>" + "EOS OSC Rx Port " + data[i].eosRxPort;

The raw data:



So as you can see, I can only seem to display the first two lines of data. I feel like this is something in the loop, but I just don't have the experience to understand what's wrong. I would appreciate any guidance. Thanks!
