method cancel

This method cancels the timer. If a new time is set, the timer is restarted.

var timerObj;
//constructor function for our sample timer listener object
function myTimerCallBack()
{
    this.handleMyTimer = handleMyTimerFunc;
}

//timer callback method
function handleMyTimerFunc()
{
    alert("This is my timer callback.");
}

//main method
function onInitialized()
{	
    var objCallback = new myTimerCallBack;
    registerMyTimerListener(objCallback, "handleMyTimer");
}

function registerMyTimerListener(myTimerCallback, methodName)
{
    timerObj = shell.serviceManager.basics.timer;
    var dateObj = new Date();
    dateObj.setMinutes(dateObj.getMinutes() + 1);
    
    // register timer callback method to fire after 1 second from the current time
    timerObj.setForOffset(myTimerCallback, methodName, 1000);
    
    alert("Cancel timer at this point and reset with new timer");    
    //cancel before the first timer fires and reset with 3 seconds
    timerObj.cancel();
    timerObj.setForOffset(myTimerCallback, methodName, 3000);
}
