AngularJS设置定时器后，再次点击按钮触发定时器，这时会出现：前一个定时器未停止，后一个定时器又启动了，导致出现多个定时器同时在运行。
2、问题源码
AngularJS之定时器无法停止 <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js">《script》 《script》 var app = angular.module("btnApp",[]); app.controller("btnCon",function($scope,$interval){ $scope.count = 0; $scope.getDayTime = function(){ var date = new Date(); var year = date.getFullYear(); var month = date.getMonth()+1; var day = date.getDate(); var hour = date.getHours(); var minute = date.getMinutes(); var second = date.getSeconds(); var thisTime = year+"-"+(month<10?"0"+month:month)+"-"+(day<10?"0"+day:day)+" "+(hour<10?"0"+hour:hour)+":"+(minute<10?"0"+minute:minute)+":"+(second<10?"0"+second:second); return thisTime; }; $scope.dayTime = $scope.getDayTime(); $scope.queryData = function(){ var timer = $interval(function(){ $scope.count++; console.log($scope.count); },4000); $scope.$on("destroy",function(){ $interval.cancel($scope.timer); }); }; }); 《script》
