Vue.js $children 按组件名称 [英] Vue.js $children by component name

问题描述

我正在尝试按名称访问特定的孩子.此刻，因为孩子在哪里，我这样称呼孩子:

I'm trying to access a specific child by name. At the moment, because of where the child is, I'm calling the child by this:

this.$root.$children[0]

只要那个孩子总是 [0] 就可以了，但是如果有办法做这样的事情就好了:

Which is ok as long as that child is always [0] but it would be great if there’s a way to do something like:

this.$root.$children['detail']

我一直认为 $refs 可能是我问题的答案，但永远找不到对我有帮助的方法.

I keep thinking $refs might be the answer to my problem but can never find a way that it helps me.

有什么想法吗?

推荐答案

您所说的这个孩子真的是您想要访问它的组件的孩子吗?在这种情况下，v-ref 确实是答案:

Is this child you are talking about really a child of the component that you want to access it from? In this case, v-ref is indeed the answer:

// in the code of the parent component, access the referenced child component like this:

this.$refs.detailsChild

<!-- Template of the parent component, assuming your child Component is called Details -->
<details v-ref:details-child></details>
