JavaScript example showing how to get information about files and subdirectories in the current remote FTP directory.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

var ftp = new CkFtp2();

ftp.Hostname = "ftp.example.com";
ftp.Username = "login";
ftp.Password = "password";

// Connect and login to the FTP server.
success = ftp.Connect();
if (success !== true) {
    console.log(ftp.LastErrorText);
    return;
}

// The ListPattern property is our directory listing filter.
// The default value is "*", which includes everything.
console.log(ftp.ListPattern);

// To get file and sub-directory information, simply
// loop from 0 to ftp.GetDirCount() - 1
var i;
var n;
n = ftp.GetDirCount();
if (n < 0) {
    console.log(ftp.LastErrorText);
    return;

    for (i = 0; i <= n - 1; i++) {

        // Display the filename
        console.log(ftp.GetFilename(i));

        // Display the file size (in bytes)
        console.log(ftp.GetSize(i));

        // Is this a sub-directory?
        if (ftp.GetIsDirectory(i) == true) {

        }

        console.log("--");

// matching the ListPattern are returned.
