如何在AngularJS的多个模块之间共享变量 [英] How to share a variable between multiple modules in AngularJS

问题描述

我是AngularJS的新手，了解基本原理.但是，我现在遇到的情况是我还不知道如何解决该问题.

I'm new to AngularJS and understand the basic principles. However, I'm having a case now where I don't yet know how to get to the solution.

让我简要说明一下情况.假设您有一家超市网上商店，那里有一个输入框，您可以在其中输入内容以搜索食物.在输入框旁边，有一个图标，显示单击时的模式以及所有订购最多的食物.

Let me briefly explain you the case. Let's say you have a supermarket webshop where there is an input box where you can type to search for your food. Next to the input box, there is an icon that displays a modal on click with all the most ordered foods.

此模式具有其自己的控制器，而输入框所在的搜索面板具有其自己的控制器.

This modal has it's own controller and the searchpanel in which the inputbox is has it's own controller.

现在，当食物售罄时，它就会在模式中被删除.但是，当所有受欢迎的食物都卖完了时，我希望模式不会在点击时显示.

Now when a food is sold out this gets striked through in the modal. But when every popular food is sold out I want the modal not to show on click.

我以为可以为模态的范围分配一个变量，但是后来我无法在搜索栏的范围内访问它.我认为我可以使用rootScope，但是我真的很想知道是否有更好的解决方案.

I thought I could assign a variable to the scope of the modal but then I couldn't access it in the scope of the searchbar. I could work with rootScope I think, but I would really like to know if there is a better solution.

在此先感谢您，如果您需要更多信息，请告诉我.

Thanks in advance and if you need more info, please let me know.

推荐答案

看看 Angular Services .

Angular服务是可替换对象，这些对象使用依赖项注入(DI)连接在一起.您可以使用服务来组织和共享应用程序中的代码.

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.
