问题描述

JavaScript 代码:
function AlbumCtrl($scope,$timeout) {$scope.counter = 0;$scope.onTimeout = function(){$scope.counter++;mytimeout = $timeout($scope.onTimeout,1000);}var mytimeout = $timeout($scope.onTimeout,1000);$scope.stop = function(){$timeout.cancel(mytimeout);}}
HTML 标记:
<头><script src="http://code.angularjs.org/angular-1.0.0rc11.min.js"></script><script src="http://documentcloud.github.com/underscore/underscore-min.js"></script><身体><div ng-controller="AlbumCtrl">{{柜台}}<button ng-click="stop()">停止</button>
</html>
I would like make a countDown with Angular js. this is my code:
Html File
<div ng-app ng-controller = "countController"> {{countDown}} <div>
js File
function countController($scope){
$scope.countDown = 10;
var timer = setInterval(function(){$scope.countDown--; console.log($scope.countDown)},1000);
}
in console.log it works I have a countdown but in {{countdown}} refresh it doesn't
could you help me please? thanks!
解决方案 Please take a look at this example here. It is a simple example of a count up! Which I think you could easily modify to create a count down.
http://jsfiddle.net/ganarajpr/LQGE2/
JavaScript code:
function AlbumCtrl($scope,$timeout) {
$scope.counter = 0;
$scope.onTimeout = function(){
$scope.counter++;
mytimeout = $timeout($scope.onTimeout,1000);
}
var mytimeout = $timeout($scope.onTimeout,1000);
$scope.stop = function(){
$timeout.cancel(mytimeout);
}
}
HTML markup:
<!doctype html>
<html ng-app>
<head>
<script src="http://code.angularjs.org/angular-1.0.0rc11.min.js"></script>
<script src="http://documentcloud.github.com/underscore/underscore-min.js"></script>
</head>
<body>
<div ng-controller="AlbumCtrl">
{{counter}}
<button ng-click="stop()">Stop</button>
</div>
</body>
</html>
