我使用以下代码作为暂停定时器:

在angularjs中使用$timeout时如何实现暂停和恢复功能

$scope.pause = function(){
             window.clearTimeout(t);
        }
timedcounter = function () {
       time = time + 1;
       localStorage.autotimertime = time;
       t = $timeout(timedcounter, 1000);
       display(time);
}

在这个代码片段中，我显示了时间，并使用了一个按钮来停止/重新启动超时。

您应该在onTimeout函数中添加您的逻辑

var app = angular.module('myapp', []);
app.controller('myCtrl', function($scope, $timeout) {
  $scope.time = 0;
  $scope.stopped = false;
  $scope.onTimeout = function() {
    $scope.time = $scope.time + 1;
    //Your logic here
    //localStorage.autotimertime = time;
    //display(time);
    mytimeout = $timeout($scope.onTimeout, 1000);
  }
  var mytimeout = $timeout($scope.onTimeout, 1000);
  $scope.stopTimeout = function() {
    $scope.stopped = true;
    $timeout.cancel(mytimeout);
  }
  $scope.restatTimeout = function() {
    $scope.stopped = false;
    mytimeout = $timeout($scope.onTimeout, 1000);
  }
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myapp" ng-controller="myCtrl">
  <p ng-bind="time"></p>
  <button ng-click="stopTimeout()" ng-show="!stopped">STOP ME !</button>
  <button ng-click="restatTimeout()" ng-show="stopped">RESUME ME!</button>
</div>

要取消一个超时请求，调用$timeout.cancel(promise).
