//$apply传播Model的变化，Angularjs外部的控制器（Dom事件，外部回调函数）必须调用$apply，需要命令angulrjs刷新自己，applay方法就是做这个事的，把要执行的函数交给$apply去执行。
app.controller(‘firstController‘,function($scope,$timeout){
$scope.name = ‘hello‘;
setTimeout(function(){
//$scope.name = ‘hi‘; 没有反映
$scope.$apply(function(){
$scope.name = ‘hi‘;
});
},2000);
//内置timeout
/*$timeout(function(){
$scope.name = ‘hi‘;
},2000);*/
$scope.show = function(){
alert(‘adssdg‘);
$scope.name = ‘hi点击事件发生了‘;
};
});
