document.querySelector("#enter").addEventListener("click", e => {
        e.preventDefault();
        var inputValue = searchApi.value; 
        fetch('https://wft-geo-db.p.rapidapi.com/v1/geo/cities/'  inputValue, options)
        .then(response => response.json())
        .then(response =>  {
            console.log(response);
            return response;
        })
        .then((data) => {

            var title = document.createElement("li")
            title.classList.add('list-item');
            title.innerText = JSON.stringify(data);
            var list = document.getElementById("result-list");
            list.appendChild(title);
        })
        .catch(err => console.error(err));
    
    });

HTML looks like this

<h2 >Results</h2>
<ul id="result-list">
  <li ></li>

</ul>

Because I use JSON stringify it turns out as it did, but I want the data to be displayed one by one and not all in one line. I have tried forEach, and for loop but I don't think I did it correctly, so any help is appreciated.

CodePudding user response：

Your data is not an array, it is a plain object-- as such, you cannot simply loop over it by index like you would an array or other iterable. If you want to get all key/value pair entries from this object into an array to iterate you can use Object.entries:

.then((data) => {
  const myData = data.data;

  Object.entries(myData).forEach(([key, val]) => {
    var title = document.createElement("li")
    title.classList.add("list-item");
    title.innerText = `${key}: ${val}`;
    var list = document.getElementById("result-list");
    list.appendChild(title);
  });
})

Note that this will probably come back in alphabetical order-- if you want a specific order, you would need to adjust your approach. You can also use the Object.entries approach for other solutions listed in your original question on this topic.
