CountDown app cannot convert string to integer using AngularJS
0
I am trying to make a countdown app. At the below code, I defined an integer variable. Then seperated it into two parts: minutes and seconds
When
$scope.remainingTime = 120;
var interval = $interval(function () {
if ($scope.remainingTime === 1) {
$interval.cancel(interval);
}
$scope.remainingTime--;
var min = Math.floor($scope.remainingTime % 3600 / 60);
var sec = Math.floor($scope.remainingTime % 3600 % 60);
var time = (min = min < 10 ? "0" + min : min) + " : " + (sec = sec < 10 ? "0" + sec : sec);
parseInt(time, 10);
$scope.remainingTime = time;
}, 1000);
For the first iteration it decriments. But then when I try to decriment it, it gives NaN error because of the time variable and when I try to parse it, it doesn't work. Any idea?

parseIntdoens't work by reference, you need to assign the result:time = parseInt(time, 10);. developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/…

another simplest solution would be to keepremainingTimeas it is, and use another variable as text for your display, so you don't need to keep parsing it back

@SafaElmalı define "doesn't work". If the issue is that it can't convert string to integer, the problem relies on the fact that you're assigning toremainingTimea string. If the script doesn't work for any other reason, that's another story.
