Layui原生upload模块不支持文件上传进度条显示，百度，谷歌找了一下不太适用。后面找到一个别人修改好的JS，替换上去，修改一下页面显示即可使用，一下是部分代码

HTML:

<div class="layui-upload">

        <button type="button" class="layui-btn layui-btn-normal" id="fileList">选择多文件</button>

        <div class="layui-upload-list">

            <table class="layui-table">

                <thead>

                <tr><th>文件名</th>

                    <th>大小</th>

                    <th>上传进度</th>

                    <th>状态</th>

                    <th>操作</th>

                </tr></thead>

                <tbody id="demoList"></tbody>

            </table>

        </div>

        <button type="button" class="layui-btn" id="fileListAction">开始上传</button>

    </div>

JS部分：

var files;

    //多文件列表示例

    var demoListView = $('#demoList')

        , uploadListIns = upload.render({

            elem: '#fileList'

            , size: 102400 //限制文件大小，单位 KB

            , exts: 'zip|rar|7z|doc|docx|pdf|txt|xls|ppt|xlsx|pptx|img|jpg|png|gif|bmp|jpeg' //只允许上传压缩文件

            , url: webroot + "/guarantee/upload/uploadFile?userid=123456"

            , accept: 'file'

            , multiple: true

            , auto: false

            , bindAction: '#fileListAction'

            , xhr: xhrOnProgress

            , progress: function (value) {//上传进度回调 value进度值

                element.progress('demoList', value + '%')//设置页面进度条

            }, xhr: function (index, e) {

                var percent = e.loaded / e.total;//计算百分比

                percent = parseFloat(percent.toFixed(2));

                element.progress('progress_' + index + '', percent * 100 + '%');

                console.log("-----" + percent);

            }

            // , data: JSON.stringify(Param)

            , choose: function (obj) {

                var files = this.files = obj.pushFile(); //将每次选择的文件追加到文件队列

                //读取本地文件

                obj.preview(function (index, file, result) {

                    var tr = $(['<tr id="upload-' + index + '">'

                        , '<td>' + file.name + '</td>'

                        , '<td>' + (file.size / 1014).toFixed(1) + 'kb</td>'

                        , '<td><div class="layui-progress layui-progress-big" lay-filter="progress_'+index+'" lay-showPercent="true"><div class="layui-progress-bar" lay-percent="0%"></div></div></td>'

                        , '<td>等待上传</td>'

                        , '<td>'

                        , '<button class="layui-btn layui-btn-xs demo-reload layui-hide">重传</button>'

                        , '<button class="layui-btn layui-btn-xs layui-btn-danger demo-delete">删除</button>'

                        , '</td>'

                        , '</tr>'].join(''));

                    //单个重传

                    tr.find('.demo-reload').on('click', function () {

                        obj.upload(index, file);

                    });

                    //删除

                    tr.find('.demo-delete').on('click', function () {

                        delete files[index]; //删除对应的文件

                        tr.remove();

                        uploadListIns.config.elem.next()[0].value = ''; //清空 input file 值，以免删除后出现同名文件不可选

                    });

                    demoListView.append(tr);

                });

            }

            ,

            before: function (obj) {

                this.data = {

                    "BUSINESS_ID": BUSINESS_ID,

                    "FLOW_ID": FLOW_ID,

                    "FLOW_NODE_ID": FLOW_NODE_ID,

                    "FILE_TYPE": FILE_TYPE

                }///携带额外的数据

            }

            ,

            done: function (res, index, upload) {

                if (res.code == 0) { //上传成功

                    var tr = demoListView.find('tr#upload-' + index)

                        , tds = tr.children();

                    tds.eq(3).html('<span style="color: #5FB878;">上传成功</span>');

                    tds.eq(4).html(''); //清空操作

                    var url = webroot + "/guarantee/itemFile/getItemFileByFlow?FLOW_ID=" + FLOW_ID + "&BUSINESS_ID=" + BUSINESS_ID + "&FLOW_NODE_ID=" + FLOW_NODE_ID + "&FILE_TYPE=" + FILE_TYPE

                    //刷新表格

                    table.reload('itemFileList', {

                        url: url

                        , where: {} //设定异步数据接口的额外参数

                        //,height: 300

                    });

                    return delete this.files[index]; //删除文件队列已经上传成功的文件

                } else if (res.code == -1) {

                    layer.msg(res.msg);

                }

                this.error(index, upload);

            }

            ,

            error: function (index, upload) {

                var tr = demoListView.find('tr#upload-' + index)

                    , tds = tr.children();

                tds.eq(2).html('<span style="color: #FF5722;">上传失败</span>');

                tds.eq(3).find('.demo-reload').removeClass('layui-hide'); //显示重传

            }

        })

    ;

注：还需替换layui的upload模块的upload.js文件
