volumedownbutton

This is an event that fires when the user presses the volume down button.

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

Details

If you need to override the default volume down behaviour you can register an event listener for the 'volumedownbutton' event.

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

Supported Platforms

  • BlackBerry WebWorks (OS 5.0 and higher)

Quick Example

document.addEventListener("volumedownbutton", onVolumeDownKeyDown, false);

    // Handle the volume down button
}

    // 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() {
        // Register the event listener
