jquery多文件上传问题

如何解决jquery多文件上传问题

我有一个用于添加文件的模式，但现在我想上传多个文件，下面是我的代码

$(document).ready(function(){
   $("#uploadArtWrokAttachment_model").modal();
});

$('#uploadAttachment').click(function(){
    $('#uploadArtworkAttachment').click();
});

$('#uploadArtworkAttachment').change(function(){
    var file = $('#uploadArtworkAttachment')[0].files[0].name;
    $('#attachmentName').html(file); 
});

                            </div>
                            <br>
                            <div class="col-md-12 text-center" style="margin-top: 5%;">
                                <label for="" id="attachmentName"></label>
                            </div>
                            <br>
                            <div class="col-md-12 text-center" style="margin-top: 5%;">
                                <input type="hidden" id="attachmentOrderId" name="attachmentOrderId" value="">
                                <img id="loader" src="{{ URL::asset('image/wait.gif') }}" style="width: 8%;">&nbsp;&nbsp;
                                <button type="button" id="saveArtWorkAttachment" class="btn btn-primary">Save</button>
                                <a class="btn btn-white" onclick="$('#uploadArtWrokAttachment_model').modal('hide')" >Close</a>
                            </div>
                        </div>
                    </div>
                </form>
            </div>
        </div>
    </div>
</div>

现在我想一次上传多个文件，因为我更改了输入文件名 uploadArtworkAttachment[] 并添加了 multiple

但我的文件仍然没有上传多个文件。

有人可以帮我吗？
