(JavaScript) Determine if Connected and Logged On

The IsConnected property indicates whether or not the FTP component has a valid TCP/IP connection (and is logged on) to the FTP server.

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 = "mylogin";
ftp.Password = "mypassword";

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

// ...

// At any point in an FTP session, the IsConnected property
// can be checked to determine if the component has remained
// connected to the FTP server.
if (ftp.IsConnected == true) {
    console.log("Connected!");
}
else {
    console.log("Not connected!");
}

// ...

success = ftp.Disconnect();
