?//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(path).value = Folder;
?return Folder;

?}
