Tinymce get image _description with file_picker_callback and image uploader

问题

TL:DR I am trying to get the value of image_description field using javascript to past it my post xhr request

Original question below

I am using file_picker_callback type image https://www.tinymce.com/docs/configure/file-image-upload/#file_picker_callback

I enabled image_description input field in my

tinymce.init({
     ....,
     image_description: true,
     ...

Everything is uploading fine but I want to pass the image_description field as well to store in the DB. But i can't grab the data

Here are my two functions, taking directly from the tinymce website

  file_picker_callback: function(cb, value, meta) {

    var input = document.createElement('input');
    input.setAttribute('type', 'file');
    input.setAttribute('accept', 'image/*');

    input.onchange = function() {
      console.log(this.files);
      var file = this.files[0];

      console.log( meta ); //I thought it might be here in the meta bt it isn't

     console.log( $('#mceu_62').val() ); //I tried to get it from its id but it returns undefined i think that field is created after this function is created.



      var id = file.name;
      var blobCache = tinymce.activeEditor.editorUpload.blobCache;
      var blobInfo = blobCache.create(id, file);
      blobCache.add(blobInfo);


      // call the callback and populate the Title field with the file name
      cb(blobInfo.blobUri(), { title: file.name });
    };

    input.click();
  },
  images_upload_handler: function (blobInfo, success, failure) {
      var xhr, formData;

      xhr = new XMLHttpRequest();
      xhr.withCredentials = false;
      xhr.open('POST', '/articles/postAcceptor');

      xhr.onload = function() {
        var json;

        if (xhr.status != 200) {
          failure('HTTP Error: ' + xhr.status);
          return;
        }

        json = JSON.parse(xhr.responseText);

        if (!json || typeof json.location != 'string') {
          failure('Invalid JSON: ' + xhr.responseText);
          return;
        }

        success(json.location);
      };

      formData = new FormData();
      formData.append('file', blobInfo.blob(), blobInfo.filename());
      formData.append('description', /*but i can't get the value*/);

      xhr.send(formData);
    }

Try this to get value:

images_upload_handler: function (blobInfo, success, failure) {
      var xhr, formData;

      xhr = new XMLHttpRequest();
      xhr.withCredentials = false;
      xhr.open('POST', '/articles/postAcceptor');

      xhr.onload = function() {
        var json;

        if (xhr.status != 200) {
          failure('HTTP Error: ' + xhr.status);
          return;
        }

        json = JSON.parse(xhr.responseText);

        if (!json || typeof json.location != 'string') {
          failure('Invalid JSON: ' + xhr.responseText);
          return;
        }

        success(json.location);
      };


      var description = '';

      jQuery(tinymce.activeEditor.dom.getRoot()).find('img').not('.loaded-before').each(
    function() {
        description = $(this).attr("alt");
        $(this).addClass('loaded-before');
    });

      formData = new FormData();
      formData.append('file', blobInfo.blob(), blobInfo.filename());
      formData.append('description', description); //found now))

      xhr.send(formData);
    }
