如何在Angular中使用$ rootScope來存儲變量？如何使用$rootScope我想稍后在另一個控制器中訪問的控制器中存儲變量？例如：angular.module('myApp').controller('myCtrl', function($scope) {
var a = //something in the scope
//put it in the root scope});angular.module('myApp').controller('myCtrl2', function($scope) {
var b = //get var a from root scope somehow
//use var b});我該怎么做？

angular.module('myApp').controller('myCtrl', function($scope, $rootScope) {
var a = //something in the scope
//put it in the root scope
$rootScope.test = "TEST";
});angular.module('myApp').controller('myCtrl2', function($scope, $rootScope) {
var b = //get var a from root scope somehow
//use var b
$scope.value = $rootScope.test;
alert($scope.value);
// var b = $rootScope.test;
// alert(b);
