var app = angular.module("myApp", []);
//$timout内置的方法
app.controller(‘firstController‘, [‘$scope‘,‘$timeout‘, function ($scope,$timeout) {
$scope.name = ‘张三‘;
$scope.age = 10;
//1，显示张三，两秒后显示李四
setTimeout(function () {
//apply 主要是传递model的变化
$scope.$apply(function () {
$scope.name = "李四";
});
},2000);
//2.方法演示
//挂载方法
$scope.show = function () {
alert("点击后的name");
}
//3.两秒后 10变成50
////timeout演示，内置函数不需要apply
$timeout(function () {
$scope.age = 50;
}, 2000);
}]);
