在Meteor中访问来自父级的子模板助手/变量

Question

Making a user picker controller and am having trouble getting the users out from parent. 制作用户选择器控制器并且无法将用户从父级中取出。

Parent template has 父模板有

{{> userPicker}}

Child updates reactive vars, stored as this.someVar = new ReactiveVar(...) . 子更新反应变量，存储为this.someVar = new ReactiveVar(...) 。

How do I get a ref to this of userPicker from parent template? 我如何获得一个裁判this的userPicker从父模板？

Answer 1

I ended up passing a dictionary by reference from the parent and had the child put stuff into it. 我最后通过父母的参考传递了一本字典，让孩子把东西放进去。

In parent html 在父html中

{{> userPicker userContext }}

In parent js 在父母js

const users = {};

And as helper 作为帮手

userContext() {
  return users;
}
