Answer 1

if I understand you correctly then

$("#target-file").bind("change", function (event) {
    var formData = new FormData($('#file-form')[0]);
    $.ajax({
            type: 'POST',
            url: '/file/processingFile',
            dataType: 'json',
            enctype: 'multipart/form-data',
            data: formData,
            contentType: false,
            processData: false,
            cache: false,
            'success': function (data) {
               
            }, 'error': function (request) {
                
            }}
    );
});
