用jQuery File Upload实现简单的文件上传

FORM中的代码：

{# file_path #}
                        <div class="form-group">
                            <label class="control-label col-md-3">
                                {{ form.file_path.label_tag }}
                                {% for error in form.file_path.errors %}
                                    <span class="label label-danger">{{ error }}</span>
                                {% endfor %}
                            </label>
                            <div id="upload-drop " class="col-md-6">

                                <span class="btn btn-success fileinput-button">

                                <i class="glyphicon glyphicon-plus"></i>

                                <span>选择上传文件</span>
                                    <input id="fileupload"  name="files[]" type="file" multiple="multiple" data-url="/version/file_upload/">
                                </span>
                                <input type="text" class="form-control" id="file_path" name="file_path"  value="" hidden readonly/>
                                <div class="progress progress-striped active">
                                    <div class="bar progress-bar-success" role="progressbar" style="width: 0%;">0%</div>
                                </div>
                            </div>
                        </div>

　　js实现：

$(document).ready(function(){

            $('#fileupload').fileupload({
                dataType: 'json',
                progressall: function (e, data) {
                    var progress = parseInt(data.loaded / data.total * 100, 10);
                    $('.progress .bar').css(
                        'width',
                        progress + '%'
                    );
                    $('.progress .bar').text(progress + '%');
                },

                done: function(e, data) {
                    uploadfilename = data.files[0].name
                    console.log(uploadfilename)
                    $('.progress .bar').text("上传完成");
                    $("#file_path").attr("value", uploadfilename);
                    $("#file_path").attr("hidden", false);
                }
            });


})
