Example – vibrate at user defined interval

edited: Jan 9, 2013, fixed issue with attached project. Note the project requires MobiOne 2.3 or greater.
Vibrate Example

The following example project demonstrates how to vibrate the device at a user defined interval using the Cordova/PhoneGap vibrate api. You must create an app from the project for the device api to function; this project will not run in the Test Center as it does not emulate the Cordova api.

The app UI consists of a SelectListMenu(spinner) for setting the frequency that the device should vibrate and a Start and Stop button. The Start and Stop buttons have attached OnClick(RunJS) actions that respectively run custom start() and stop() javascript functions that I have created (see code below). The start() function starts a javascript timer (setInterval() js function) that runs at the frequency in seconds specified in the SelectListMenu. The stop() function clears the timer using the clearInterval() function.The Start button also serves as a restart action if the timer is already running.

The mobione design file for this app is attached at the bottom.

See attachment vibrate-ss.png

The app javascript is available in the vibrate_custom.js file.

//-----------------------------------
timerId = -1;
frequency = 1; //seconds
isRunning = false;
showNoCordovaMsg = true;
VIBRATE_DURATION = 250; //milliseconds
COLOR_GREEN = '#007000';
COLOR_RED = '#E10000';

function start() {
  if (showNoCordovaMsg && !phoneui.cordovaAvailable ()) {
     alert('Vibrate feature is only available for \nHTML5 apps. ');
     showNoCordovaMsg = false;
  }
  if (isRunning) { //restart
    stop();
    start();
    return;
  }
  isRunning = true;
  showStatus('Running...',COLOR_GREEN);
  frequency = $('select[name="frequency"]').val()
  timerId = setInterval(
              function() {
                if (phoneui.cordovaAvailable ()){
                  navigator.notification.vibrate(VIBRATE_DURATION);
                }
              },
              frequency * 1000 + VIBRATE_DURATION);
}

function stop() {
  if (!isRunning) return;
  
  isRunning = false;
  clearInterval(timerId);
  showStatus('Stopped',COLOR_RED);
}

....
