This is an event that fires when a Cordova application is online (connected to the Internet).

document.addEventListener("online", yourCallbackFunction, false);


When the application's network connection changes to being online, the online event is fired.

Typically, you will want to attach an event listener with document.addEventListener once you receive the Cordova 'deviceready' event.

Supported Platforms

  • Android
  • BlackBerry WebWorks (OS 5.0 and higher)
  • iOS
  • Windows Phone 7

Quick Example

document.addEventListener("online", onOnline, false);

function onOnline() {
    // Handle the online event

Full Example

    <title>Cordova Online Example</title>

    <script type="text/javascript" charset="utf-8" src="cordova-1.8.0.js"></script>
    <script type="text/javascript" charset="utf-8">

    // Call onDeviceReady when Cordova is loaded.
    // At this point, the document has loaded but cordova-1.8.0.js has not.
    // When Cordova is loaded and talking with the native device,
    // it will call the event `deviceready`.
    function onLoad() {
        document.addEventListener("deviceready", onDeviceReady, false);

    // Cordova is loaded and it is now safe to make calls Cordova methods
    function onDeviceReady() {
        document.addEventListener("online", onOnline, false);

    // Handle the online event
    function onOnline() {

  <body onload="onLoad()">

iOS Quirks

During initial startup, the first online event (if applicable) will take at least a second to fire.

Windows Phone 7 Quirks

When running in the Emulator, the connection.status of the device is always unknown, and this event will NOT fire.
