I put the code first so now i can write the question. I am trying to make a slideshow. As you can see in the .sidenav, I have 4 <li> elements that are commented. They should be added with Jquery and filled with JSON. In the JSON part I am trying to make a <li> for every img ...thereby 4 elements in this case , and fill them with src and alt . But , all I get is empty . Nothing . There are no errors but when I check if something was added , I can see this :
Why is it unknown? Any thoughts ?

Answer 1

As i cannot replicate your exact code and values i made a simple snippet below.
I don't know why you use i++ because the each function has an index as argument and you can use it.
In the below snippet everything works ( i think ) as you expected.
let result = [{
"src": "./images/slide-1.png",
"alt": "Slide one"
}, {
"src": "./images/slide-2.png",
"alt": "Slide two"
}, {
"src": "./images/slide-3.png",
"alt": "Slide three"
}, {
"src": "./images/slide-4.png",
"alt": "Slide four"
}, {
"src": "./images/slide-5.png",
"alt": "Slide five"
}, {
"src": "./images/slide-6.png",
"alt": "Slide six"
}];
for (i = 0; i < result.length; i++) {
$('.image').append(`<li class="selected"><img src="${result[i].src}" alt="${result[i].alt}"></li>`);
}

</ul>
