I have found this code for a countdown timer and tweaked it a little.
angular.module('app').directive('countdown', [
'Util', '$interval', function (Util, $interval) {
return {
restrict: 'A',
scope: {
date: '@'
},
link: function (scope, element) {
var future;
future = new Date(scope.date);
$interval(function () {
var diff;
diff = Math.floor((future.getTime() - new Date().getTime()) / 1000);
var d = Util.dhms(diff);
var el = "<div class='time_division_container'><div class='digits_container'>"+d[0]+"</div><div class='label_container'>DAYS</div></div><div class='time_division_container'><div class='digits_container'>"+d[1]+"</div><div class='label_container'>HOURS</div></div><div class='time_division_container'><div class='digits_container'>"+d[2]+"</div><div class='label_container'>MINUTES</div></div><div class='time_division_container'><div class='digits_container'>"+d[3]+"</div><div class='label_container'>SECONDS</div></div>";
return element.replaceWith(el);
}, 1000);
}
};
}
]).factory('Util', [
function () {
return {
dhms: function (t) {
var days, hours, minutes, seconds;
days = Math.floor(t / 86400);
t -= days * 86400;
hours = Math.floor(t / 3600) % 24;
t -= hours * 3600;
minutes = Math.floor(t / 60) % 60;
t -= minutes * 60;
seconds = t % 60;
return [days, hours, minutes, seconds];
}
};
}
]);
Basically all I wanted to happen is to put the days, hours, minutes and seconds in this template:
<div class='time_division_container'>
<div class='digits_container'>{{ days }}</div>
<div class='label_container'>DAYS</div>
</div>
<div class='time_division_container'>
<div class='digits_container'>{{ hours }}</div>
<div class='label_container'>HOURS</div>
</div>
<div class='time_division_container'>
<div class='digits_container'>{{ minutes }}</div>
<div class='label_container'>MINUTES</div>
</div>
<div class='time_division_container'>
<div class='digits_container'>{{ seconds }}</div>
<div class='label_container'>SECONDS</div>
</div>
Using the directive I placed it like this:
<div countdown='' date='January 1, 2018 12:00:00'> </div>
It was displaying the template but the timer is not moving. What could be causing this? Please help. Thanks.
Alright, I know I am new to angular. Just found out by trying
return element.html(el);
instead of
return element.replaceWith(el);
and now it works.
@
is for a one-way databinding. This means that if you change your value in your controller/directive, the view won't be updated.
Use =
for a two-way databinding and reflect changes on view.
scope: {
date: '='
