js 选择本地文件夹，上传文件夹

js 选择本地文件夹，上传文件夹

适用于IE浏览器，而且需要设置安全级别，ActiveX插件前3项为启用

1.html页面代码

<input type="text" id="FolderPath" name="FolderPath" size="20"/>                            
<input type="button" id="selectFolder" value="选择文件夹" />

2.js 代码

$('#selectFolder').click(function() {
        try {  
            var Message = "\u8bf7\u9009\u62e9\u6587\u4ef6\u5939";  //选择框提示信息  
            var Shell = new ActiveXObject("Shell.Application");  
            //var Folder = Shell.BrowseForFolder(0, Message, 64, 17);//起始目录为：我的电脑  
            var Folder = Shell.BrowseForFolder(0,Message,0); //起始目录为：桌面  
            if (Folder != null) {  
                Folder = Folder.items();  // 返回 FolderItems 对象  
                Folder = Folder.item();  // 返回 Folderitem 对象  
                Folder = Folder.Path;   // 返回路径  
                if (Folder.charAt(Folder.length - 1) != "\\") {  
                    Folder = Folder + "\\";  
                }  
                document.getElementById('FolderPath').value = Folder;
                return Folder;  
            }  
        }  
        catch (e) {  
            alert(e.message);  
        }  
    });


给id="FolderPath"的input复制
var folderpath = document.getElementById("FolderPath").value;

用其他字符替换掉斜杠/
folderpath = folderpath.replace(/\\/g,'-');

提交form表单
$('#formid').submit();

java代码把路径中的斜杠/替换回来
folderpath = folderpath.replaceAll("-", "/");

List<File> list = new ArrayList<File>();
List<File> fileList = blFile(list, folderpath);
/*

        for (File f : files) {  
            if (f.isFile()) {  
                fileList.add(f);  
            } else if (f.isDirectory()) {  
                blFile(fileList,f.getAbsolutePath());  
            }  
        }  
       }
       return fileList;
   }
