我正在尝试在angularJS中实现一个简单的计时器。但是，尽管每个人都建议超时功能不起作用。
<!doctype html>
<html lang="en">
<head>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.2.15/angular.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.2.15/angular-sanitize.min.js"></script>
</head>
<body>
<div ng-app="ss" ng-controller="mainCtrl">
{{timeInMs}}
</div>
<script>
var myApp = angular.module("ss", ['ngSanitize']);
myApp.controller('mainCtrl', function ($sce, $scope) {
$scope.timeInMs = 10;
var countUp = function() {
$scope.timeInMs+= 500;
$timeout(countUp, 500);
}
$timeout(countUp, 500);
});
</script>
</body>
</html>
当我注释掉“ $ timeout（countUp，500）;”时行，代码可以正常工作，但计时器不起作用。我还需要添加其他JavaScript文件吗？
提前致谢。
最佳答案
您必须将$timeout服务注入控制器
var myApp = angular.module("ss", []);
myApp.controller('mainCtrl', function ($sce, $scope, $timeout) {
$scope.timeInMs = 10;
var countUp = function () {
$scope.timeInMs += 500;
$timeout(countUp, 500);
}
$timeout(countUp, 500);
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="ss" ng-controller="mainCtrl">
{{timeInMs}}
</div>
