如何在不使用rootScope或URL参数的情况下在AngularJS中的两个状态之间发送对象？

When I navigate between one state to another, I want to pass an object to be used in the new state. How can I do this without using global object solutions such as $rootScope? Also I don't want to use the state url parameters.

当我在一个状态到另一个状态之间导航时,我想传递一个要在新状态下使用的对象。如何在不使用全局对象解决方案(如$ rootScope)的情况下执行此操作?另外我不想使用状态url参数。

Basically, I want to do $state.go('myState', {some: 'thing'}) and inside the controller for "myState" I want to be able to reach the passed object somehow.

基本上,我想做$ state.go('myState',{some:'thing'})并在控制器内部为“myState”我希望能够以某种方式到达传递的对象。

3 个解决方案

#1

I assume that by "two states" you mean two different controllers, each of them accessible through different routes.

我假设“两个状态”是指两个不同的控制器,每个控制器可以通过不同的路径访问。

Angular would recommend to use a service for that as the doc says :

Angular建议使用服务,因为文档说:

Angular services are substitutable objects that are wired together using dependency injection (DI). You can use services to organize and share code across your app.

角度服务是使用依赖注入(DI)连接在一起的可替换对象。您可以使用服务在整个应用中组织和共享代码。

What do you mean between states? If you mean between controllers, then you could use a shared service to hold the data. Services are singletons, so live for the lifetime of the page.

国家之间是什么意思?如果您的意思是控制器之间,那么您可以使用共享服务来保存数据。服务是单身,所以在页面的生命周期中都是如此。

#3

you can access state parameters in your

你可以访问你的状态参数

.controller('ctrl',['$scope','$stateParams',function($scope , $stateParams ) {    

          $scope.getParams = function() {
              console.log( $stateParams.some ); 
          }

    }
