How to stop setTimeInterval function manually in smartface? - smartface.io

Question

I create a setInterval method like below, I want to stop it anytime from anywhere. By the way, that function is in a if-else statement, so I cannot access the stop function.
How can it be possible?
var intervalID = setInterval(function () {
if (flag) {
stopTimer();
Pages.Page1.Label1.text = "";
}
if (time == 0) {
stopTimer();
Pages.Page1.Label1.text = "";
Device.makeCall(callNumber.rows[0][0]);
} else
updateTime();
}, 1000);
function updateTime() {
time = time - 1;
Pages.Page1.Label1.text = time;
}
function stopTimer() {
clearInterval(intervalID);
}

Answer 1

Just set the flag variable to true.
flag = true;
Alternatively, i would suggest to declare your functions outside of the if / else scope .
For instance, create a timer instance with start / stop methods as such :
timer = function() {};
timer.prototype.start = function ()
{
this.timerId = setInterval(function () {
/* ... */
/* call to doWork here or simply your code */
}, 1000);
}
timer.prototype.doWork = function ()
{
// override here if you want and wall doWork in setInterval
}
timer.prototype.stop = function ()
{
clearInterval(this.timerId);
}
var t = new timer();
// start the timer
t.start();
// stop the timer
t.stop();
This way you can handle your timer as you want.
