How to upload a file from local path?

Question

Here is my problem, I would like to upload a file from a local path but i can't change input file value because it is impossible

The classical code of simple file upload :

HTML-code:

<input id="file" type="file" />
<progress id="progress"></progress>

JavaScript-code:

var fileInput = document.querySelector('#file'),
    progress = document.querySelector('#progress');

fileInput.addEventListener('change', function() {

    var xhr = new XMLHttpRequest();

    xhr.open('POST', 'upload.html');

    xhr.upload.addEventListener('progress', function(e) {
        progress.value = e.loaded;
        progress.max = e.total;
    }, false);

    xhr.addEventListener('load', function() {
        alert('Upload terminé !');
    }, false);

    var form = new FormData();
    form.append('file',         fileInput.files[0]);

    xhr.send(form);

  }, false);

How can we change it?

I'm confused, do you mean you want to know how to handle the upload request via AJAX? — Halfpint

On @PM77-1 question: It is forbidden to retrieve the full path to a file due to security policies by modern browsers. A malicious coder could use this to retrieve information about your machine. — Mouser

You can't do it with pure JS. Modern browsers prevent you from direct work with the user's filesystem due to obvious insecurity. However, you can try to do it using Flash, ActiveX, Silverlight and so on.
