1.在webuploader.js大概4880行代码左右，在动态生成的input组件的下面（也可以直接搜索input），增加webkitdirectory属性。

function FileUploader(fileLoc, mgr)

{

var _this = this;

this.id = fileLoc.id;

this.ui = { msg: null, process: null, percent: null, btn: { del: null, cancel: null,post:null,stop:null }, div: null};

this.isFolder = false; //不是文件夹

this.app = mgr.app;

this.Manager = mgr; //上传管理器指针

this.event = mgr.event;

this.Config = mgr.Config;

this.fields = jQuery.extend({}, mgr.Config.Fields, fileLoc.fields);//每一个对象自带一个fields幅本

this.State = this.Config.state.None;

this.uid = this.fields.uid;

this.fileSvr = {

pid: “”

, id: “”

, pidRoot: “”

, f_fdTask: false

, f_fdChild: false

, uid: 0

, nameLoc: “”

, nameSvr: “”

, pathLoc: “”

, pathSvr: “”

, pathRel: “”

, md5: “”

, lenLoc: “0”

, sizeLoc: “”

, FilePos: “0”

, lenSvr: “0”

, perSvr: “0%”

, complete: false

, deleted: false

};//json obj，服务器文件信息

this.fileSvr = jQuery.extend(this.fileSvr, fileLoc);

2.可以获取路径

this.open_files = function (json)

{

for (var i = 0, l = json.files.length; i < l; ++i)

{

this.addFileLoc(json.files[i]);

}

setTimeout(function () { _this.PostFirst(); },500);

};

this.open_folders = function (json)

{

for (var i = 0, l = json.folders.length; i < l; ++i) {

this.addFolderLoc(json.folders[i]);

}

setTimeout(function () { _this.PostFirst(); }, 500);

};

this.paste_files = function (json)

{

for (var i = 0, l = json.files.length; i < l; ++i)

{

this.addFileLoc(json.files[i]);

}

};

后端代码逻辑大部分是相同的，目前能够支持MySQL,Oracle,SQL。在使用前需要配置一下数据库，可以参考我写的这篇文章：http://blog.ncmem.com/wordpress/2019/08/07/java超大文件上传与下载/
