app.controller('firstController',function($scope,$rootScope){
$scope.name='张三';
$rootScope.age='30';
});
app.controller('secondController',function($scope,$rootScope){
// $scope.name='张三';
$rootScope.age='30';
}); second
1:$rootScope 全局变量
2: secondController会继承到first中的name
3:依赖注入中代码压缩的问题
app.controller("firstController",["$scope",function($scope){
$scope.name="heqiang";
}])
4:run()
方法初始化全局的数据 ,只对全局作用域起作用 如$rootScope
var m1 = angular.module('myApp',[]);
m1.run(['$rootScope',function($rootScope){
$rootScope.name = 'hello';}]);
