html & angularJS-一個簡單的10s倒計時

html:

<!-- Countdown -->
 <div style="margin: 30px auto; width: 45px; height: 45px; border: 3px solid gray; border-radius: 30px; text-align: center; line-height: 42px; vertical-align: middle; color: blue;">
            {{countdown}}
</div>

JS:

$scope.countdown = 10;
var myTime = setInterval(function() {
                                 $scope.$apply(function() {
                                            $scope.countdown--;
                                               });
                                 }, 1000);

// 倒計時10-0秒，但算上0的話就是11s
setTimeout(function() {
                   clearInterval(myTime);
                   $scope.countdown.$destroy();
        }, 11000);    

 

其實也能夠用內置服務$timeout作，可在界面的刷新方面總弄很差，還在探索中...
