1、问题背景

设置一个定时器，给定两个变量startData和endData，计时开始后分别减去5和50；单击停止暂停定时器，重置后数据恢复到原来的数据。

2、实现源码

<!DOCTYPE html><html><head><meta charset="UTF-8"><title>AngularJS停止定时器</title><script src="http://cdn.static.runoob.com/libs/angular.js/1.4.6/angular.min.js"></script><script>var app = angular.module("intervalApp",[]);app.controller("intervalController",["$scope","$interval",function($scope,$interval){$scope.startData = 100;$scope.endData = 1000;var stopEvent;$scope.startEvent = function(){if(angular.isDefined(stopEvent)) return;stopEvent = $interval(function(){if($scope.startData > 50 && $scope.endData > 500){$scope.startData = $scope.startData - 5;$scope.endData = $scope.endData - 50;}else{$scope.stopClick();}},1000)};$scope.stopClick = function(){if(angular.isDefined(stopEvent)){$interval.cancel(stopEvent);stopEvent = undefined;}};$scope.resetEvent = function(){$scope.startData = 100;$scope.endData = 1000;};$scope.$on("$destory",function(){$scope.stopClick();});}]);</script></head><body ng-app="intervalApp"><div ng-controller="intervalController"><button data-ng-click="startEvent()">开始</button><button data-ng-click="stopClick()">停止</button><button data-ng-click="resetEvent()">重置</button><br><div>开始数据：{{startData}}</div><br><div>结束数据：{{endData}}</div><br></div></body></html>

3、实现结果

（1）初始化

（2）点击开始

（3）点击停止

（4）点击重置
