AngularJS实现页面定时刷新 切换页面停止刷新

代码如下：

app.controller('businessCtrl', function($scope, $interval, $http) {$scope.shuaxin = function() {getTransCodes(i_pagenum, i_pagesize, $http, $scope);}getTransCodes(i_pagenum, i_pagesize, $http, $scope);var autoRefresh;//自动刷新autoRefresh = $interval($scope.shuaxin, 1000);//停止自动刷新$scope.stopAutoRefresh = function() {if(autoRefresh) {k = 0;$interval.cancel(autoRefresh);autoRefresh = null;}};//切换页面时停止自动刷新$scope.$on('$routeChangeStart', function(angularEvent, current, previous) {$scope.stopAutoRefresh();});});function getTransCodes(i_pagenum, i_pagesize, $http, $scope){......}
