如图所示:

可以返回目录路径。

操作如下:

function BrowseFolder(){ 
try{ 
var Message = "请选择文件夹"; //选择框提示信息 
var Shell = new ActiveXObject( "Shell.Application" ); 
var Folder = Shell.BrowseForFolder(0,Message,0x0040,0x11);//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 + "\\"; 
} 
return Folder; 
} 
return null; 
}catch(e){ 
alert("请在ie设置中启用AcitveX控件相关选项。"); 
return null; 
} 
}
var Folder = BrowseFolder();
Copy after login

这里这个Folder即为选择目录确定之后返回的路径。

假设我选中的是E盘的works目录,则返回值为E:\works\

注意:有时可能会提示没有权限之类的,因为是客户端js操作,所以需要在internet选项的安全自定义里把ActiveX的一些选项给启用。
