JavaScript：读取文件夹中的文件 [英] JavaScript: Read files in folder

问题描述

编辑：我正在尝试读取特定文件夹中的所有文件并列出其中的文件，而不是读取特定文件的内容。我只是尝试简单地创建一个FileSystemObject，它也没有做任何事情。我显示一个警告（弹出）beforfe制作FileSystemObject，然后一个警告（未显示）。所以问题在于简单地创建对象。

I'm trying to read all the files in a specific folder and list the files in there, not read the content of a specific file. I just tried to simply create an FileSystemObject and it doesn't do anything either. I show an alert (which pops up) beforfe making the FileSystemObject, and one after it (which isn't shown). So the problem is in simply creating the object.

原文：

我正在尝试读取文件夹中的所有文件使用JavaScript。

I am trying to read all the files in a folder by using JavaScript.

这是一个本地HTML文件，它不会在服务器上，所以我不能使用PHP。

It is a local HTML file, and it will not be on a server, so I can't use PHP I guess.

现在我正在尝试读取特定给定文件夹中的所有文件，但它没有做任何关于我做 FileSystemObject

Now I'm trying to read all the files in a specific given folder, but it doesn't do anything on the point I make a FileSystemObject

这是我使用的代码，警报显示为2，然后停止。

Here is the code I use, The alert shows until 2, then it stops.

    alert('1');
    var myObject, afolder, date;
    alert('2');
    myObject = new ActiveXObject("Scripting.FileSystemObject");
    alert('3');
    afolder = myObject.GetFolder("c:\\tmp");
    alert('4');
    date = afolder.DateLastAccessed;
    alert("The folder"+name+" is a temporary folder.");

我这样做是否正确？

谢谢！

推荐答案

此解决方案仅适用于IE11或更早，因为它是基于MS的

<script type="text/javascript"> 
    var fso = new ActiveXObject("Scripting.FileSystemObject"); 

    function showFolderFileList(folderspec) {    
        var s = "";
        var f = fso.GetFolder(folderspec);

        // recurse subfolders
        var subfolders = new Enumerator(f.SubFolders);
        for(; !subfolders.atEnd(); subfolders.moveNext()) {
            s += ShowFolderFileList((subfolders.item()).path);
        }  

        // display all file path names.
        var fc = new Enumerator(f.files);
        for (; !fc.atEnd(); fc.moveNext()) {
            s += fc.item() + "<br>";
        }
        return s; 
    }

    function listFiles() {
        document.getElementById('files').innerHTML = showFolderFileList('C:');
    }
</script>

<input type='button' onclick='listFiles()' value='List Files' />
<div id="files" />
