$timeout&$interval對原生Javascript中的setTimeout和?setInterval進行封裝 ??
var app = angular.module('app',[]); ?????
app.controlle('xmgController'，['$scope','$timeout','$interval',function ($scope,$timeout,$interva l) {
$scope.name = 'xmg'; ??????
$timeout(function () { $scope.name="xmg123"; },1000); ?????????
var timer = $interval(function () { $scope.dateTime = new Date(); },1000); ??????????
$scope.stop = function () { alert('aaa'); ???????? $interval.cancel(timer); } }]); <p>{{name}}</p> <p>{{dateTime | date:'yyyy-MM-dd h:m:s'}}</p> <button ng-click="stop()">??</button>
記住是$timeout&$interval第一個延時第二個循環(huán)
停止循環(huán)調(diào)用$interval.cancel
angular中：的面試題
1/如何停止一個定時器; 調(diào)用cancel方法
2/如何取消數(shù)據(jù)監(jiān)聽（watch）
