博客提到在传参时，需要传参的参数要在before对应相应的参数名，涉及信息技术中传参相关内容。

layui.use('upload', function () {

            var $ = layui.jquery

                , upload = layui.upload;



            //普通图片上传

            var uploadInst = upload.render({

                elem: '#avatar'

                ,url: '{$webname}/personal/uploadimg'

                ,accept: 'images'

                ,auto: true

                ,before: function (obj) {

                    this.data = { 'id': '445' };

                    //预读本地文件示例，不支持ie8

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

                        $('#img').attr('src', result); //图片链接（base64）

                    });

                }

                ,done: function (res) {

                    if (res.code == 0) {

                        layer.msg(res.msg);

                    } else {

                        layer.msg(res.msg);

                    }

                }

            });

        })

需要传参的参数就在before在对应的参数名
