[英]pass the value from one page to another using rootscope in angularJS
[英]pass value from one different app module controller to another app module service using $rootScope in angularjs
我正在用angularjs做項目,我的需求是需要使用$ rootScope將值從一個不同的應用程序模塊控制器傳遞給另一個應用程序模塊服務
Here my part of code
登錄模塊和控制器
var loginApp = angular.module('loginApp', [ 'ngCookies' ]);
loginApp.controller('loginCtrl', function($scope, $cookies, $cookieStore,
$rootScope) {
$scope.redirect = function() {
if ($scope.name == 'admin' && $scope.password == 'admin') {
$rootScope.loggedInUser = $scope.name;
window.location = "pages/index.html";
} else
alert('User / Password Invalid');
}
});
這是我的app.js文件
我將登錄模塊注入了另一個模塊
var smartCities = angular.module('smartCities', [ 'ngRoute', 'ngAnimate',
'ui.bootstrap', 'ngTouch', 'ui.grid.exporter', 'ui.grid',
'ui.grid.selection', 'ui.grid.autoResize', 'ngCookies', 'loginApp' ]);
下面我在這里訪問loggedInuser
smartCities.run(function($rootScope, $location, $cookies, $cookies,
$cookieStore) {
$rootScope.$on("$routeChangeStart", function(event, next, current) {
console.log($rootScope.loggedInUser);
$location.path(next.$$route.originalPath);
});
});
但在控制台中,我收到類似
undifined
請告訴我我做錯了什么
您可以為此目的使用本地存儲或會話存儲。
登錄控制器:
loginApp.controller('loginCtrl', function($scope, $cookies, $cookieStore,
$rootScope) {
$scope.redirect = function() {
if ($scope.name == 'admin' && $scope.password == 'admin') {
localStorage.loggedInUser = $scope.name;
window.location = "pages/index.html";
} else
alert('User / Password Invalid');
}
登錄用戶:
smartCities.run(function($rootScope, $location, $cookies, $cookies,
$cookieStore) {
$rootScope.$on("$routeChangeStart", function(event, next, current) {
console.log(localStorage.loggedInUser);
$location.path(next.$$route.originalPath);
});
這是文檔鏈接: https : //docs.angularjs.org/api/ng/type/angular.Module#value
//this is one module
var myUtilModule = angular.module("myUtilModule", []);
// this is value to be shared among modules, it can be any value
myUtilModule.value ("myValue" , "12345");
//this is another module
var myOtherModule = angular.module("myOtherModule", ['myUtilModule']);
myOtherModule.controller("MyController", function($scope, myValue) {
// myValue of first module is available here
}
myOtherModule.factory("myFactory", function(myValue) {
return "a value: " + myValue;
});
