使用javascript掃描目錄

我知道在Web應用程序中執行此操作時存在一些問題，但是我只是爲我自己的PC編寫自己的腳本，並且正在使用JavaScript編寫腳本。我知道，你可以通過調用獲取文件系統對象：使用javascript掃描目錄

var Fo = new ActiveXObject("Scripting.FileSystemObject")

有沒有可以讓我瀏覽，我希望有一個特定的文件夾的方法？我以前沒有使用JavaScript，所以我不確定要查找什麼。

謝謝

編輯：我錯過了。顯然就是我使用是的JScript這是不完全一樣的東西，如JavaScript

我想通了。一旦我知道我正在尋找JScript ...

var objShell = new ActiveXObject("Shell.Application"); 
var lib; 
lib = objShell.BrowseForFolder(0,"Select Library Folder",0);

作爲JavaScript的新手，請記住，您必須調整您的代碼到不同的瀏覽器！ – clamchoda 2011-04-19 18:24:09

沒有在瀏覽器中運行它，只需雙擊JScript文件在我的電腦上運行它 – JPC 2011-04-19 18:42:37

尷尬，但我甚至不知道你可以做到這一點。誰是JavaScript新手現在哈哈！ - 所以如果你把警報（「你好世界」）;到一個.js文件，你可以雙擊文件，它會提醒你好世界？ – clamchoda 2011-04-19 18:45:52

代碼來調用文件夾對話框：

<script language="JavaScript"> 
function getFolder(){ 
    return showModalDialog("folderDialog.html","","width:400px;height:400px;resizeable:yes;"); 
} 
</SCRIPT> 
<body> 
<form> 
<input type="text" name="yourFieldName"><input type="button" value="Browse..." onclick="this.form.yourFieldName.value=getFolder()">
