选择文件要保存的具体位置

<input type=button value="选择路径" onclick="BrowseFolder()"/><script>    function BrowseFolder(){        var Message = "请选择文件夹";        var Shell = new ActiveXObject("Shell.Application");        var Folder = Shell.BrowseForFolder(0, Message, 0x0040, 0x11);        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 + "\\";            }            alert(Folder);        }    }</script>

?这样可以自己选择想要保存文件的位置。
