Find files with JavaScript

• Download source and demo files - 2 Kb

Introduction

Maybe you want to have list of  server or client files in your web page to uploading or downloading or changing . JScript allow you to do this. You can capture all files type , size , properties in all directories and use them easily. In this sample I use this technique for searching files in local hard drive.

Necessary Attention: your browser should have access to run ActiveX objects. If receive a error message telling "Automatic Server Can't Create Object" you most go to Internet Option and in security tab select custom level in Local part and change options to get effect.

ActiveX Objects

For working with Files and directory you should make a server object as Scripting.FileSystemObject then with GetDirectory() method can get a directory object. If you want know the directory is use FolderExists().

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

Enumerator

Enumerators are an array of Directory or File objects such that you can use methods to get special file or sub directory that are in defined path. Enumerator have some methods I have called like atEnd() and moveNext() in my sample.

function FindFile(FOo)
{
    //Get array of files including in FOo directory object

    var FSo = new Enumerator(FOo.Files);
    
    // Getting all files in FSo object

    for (i=0;!FSo.atEnd();FSo.moveNext())

    ...
}

Files Object Properties

For getting a object that is in Enumerator object you must use item() and it returns a file or directory object that are in current place of Enumerator. Then you can use Files properties that are listed.
