选择文件要保存的具体位置

在开发的时候，有的时候需要让用户选择文件所在路径，在这里整理一下，说不定以后还用的着

"选择路径" οnclick="BrowseFolder()"/>
  </span></li> 
     <li class="alt"><span>    </span><span class="keyword">function</span><span> BrowseFolder(){  </span></li> 
     <li><span>        </span><span class="keyword">var</span><span> Message = </span><span class="string">"请选择文件夹"</span><span>;  </span></li> 
     <li class="alt"><span>        </span><span class="keyword">var</span><span> Shell = </span><span class="keyword">new</span><span> ActiveXObject(</span><span class="string">"Shell.Application"</span><span>);  </span></li> 
     <li><span>        </span><span class="keyword">var</span><span> Folder = Shell.BrowseForFolder(0, Message, 0x0040, 0x11);  </span></li> 
     <li class="alt"><span>        </span><span class="keyword">if</span><span> (Folder != </span><span class="keyword">null</span><span>) {  </span></li> 
     <li><span>            Folder = Folder.items();</span><span class="comment">//返回FolderItems对象    </span><span> </span></li> 
     <li class="alt"><span>            Folder = Folder.item();</span><span class="comment">//返回Folderitem对象    </span><span> </span></li> 
     <li><span>            Folder = Folder.Path;</span><span class="comment">//返回路径    </span><span> </span></li> 
     <li class="alt"><span>            </span><span class="keyword">if</span><span> (Folder.charAt(Folder.length - 1) != </span><span class="string">"\\"</span><span>) {  </span></li> 
     <li><span>                Folder = Folder + </span><span class="string">"\\"</span><span>;  </span></li> 
     <li class="alt"><span>            }  </span></li> 
     <li><span>            alert(Folder);  </span></li> 
     <li class="alt"><span>        }  </span></li> 
     <li><span>    }  </span></li> 
     <li class="alt"><span>

 这样可以自己选择想要保存文件的位置。
