var myForm = document.getElementById('formAjax');  // Our HTML form's ID
var myFile = document.getElementById('fileAjax');  // Our HTML files' ID
var statusP = document.getElementById('status');
 
myForm.onsubmit = function(event) {
    event.preventDefault();
 
    statusP.innerHTML = 'Uploading...';
 
    // Get the files from the form input
    var files = myFile.files;
 
    // Create a FormData object
    var formData = new FormData();
 
    // Select only the first file from the input array
    var file = files[0]; 
 
    // Check the file type
    if (!file.type.match('image.*')) {
        statusP.innerHTML = 'The file selected is not an image.';
        return;
    }
 
    // Add the file to the AJAX request
    formData.append('fileAjax', file, file.name);
 
    // Set up the request
    var xhr = new XMLHttpRequest();
 
    // Open the connection
    xhr.open('POST', '/uploadHandling.php', true);
 
    // Set up a handler for when the task for the request is complete
    xhr.onload = function () {
      if (xhr.status == 200) {
        statusP.innerHTML = 'Upload complete!';
      } else {
        statusP.innerHTML = 'Upload error. Try again.';
      }
    };
 
    // Send the data.
    xhr.send(formData);
}

j'ai essayé de contacter son concepteur, malheureusement sans réponse.
J'ai essayé de mettre toutes les autorisations du repertoire "./uploads/"
j'ai systématiquement le message "Upload error. Try again."

Si vous avez du courage et désirez m'aider : merci
