How to upload an image to ImgBB API using Javascript in a firefox addon

问题

Info on the API can be found here. It does not give any details for using with Javascript, only with curl.

Have tried numerous different methods from old posts on here but this is the closest I have got so far.

function main() {
    var ul = document.querySelector('.redactor_toolbar')

    if(ul != null)
    {
        var new_li = document.createElement('li')
        var new_a = document.createElement('a')
        new_li.appendChild(new_a)
        ul.appendChild(new_li)

        new_a.addEventListener('click', function() {
            var input = document.createElement('input');
            input.type = 'file';

            input.onchange = e => {
                uploadImage(e.target.files[0])
            }

            input.click();
        })
    }
 }

 async function uploadImage(img)
 {
    var form = new FormData();
    form.append('image', img)

    var url = 'https://api.imgbb.com/1/upload?key=8d5867a9512390fb5e5dc97839aa36f6' 

    const config = {
        method: 'POST',
        headers: {
            'Accept': 'application/json',
            'Access-Control-Allow-Origin': '*',
            'Connection': 'keep-alive',
            'Content-Type': 'application/json',
        },
        body: form
    }

    const response = await fetch(url, config)
    const json = await response.json()

    console.log(response)
 }

The JSON response:

is the same problem for mi application.

Create

<input type="file" id="input_img" onchange="fileChange()" accept="image/*">

The code javascript

function fileChange(){
var file = document.getElementById('input_img');
var form = new FormData();
form.append("image", file.files[0])

var settings = {
  "url": "https://api.imgbb.com/1/upload?key=8d5867a9512390fb5e5dc97839aa36f6",
  "method": "POST",
  "timeout": 0,
  "processData": false,
  "mimeType": "multipart/form-data",
  "contentType": false,
  "data": form
};


$.ajax(settings).done(function (response) {
  console.log(response);
  var jx = JSON.parse(response);
  console.log(jx.data.url);


});

}

This work for me
