How to get DOM element of current Vue component?
提问by Kamil Kie?czewski
When I'm inside some method in vue commponent and want to use some dom manipulation (by jquery) I need to get DOM element coresponnding to my component (especially in case when I have many instances of my component on page - I need to 'work' separately on each of them - so I cannot detect DOM element using only jquery selector without tricks...)
当我在 vue 组件中的某个方法中并想要使用一些 dom 操作(通过 jquery)时,我需要让 DOM 元素与我的组件关联(尤其是在页面上有很多组件实例的情况下 - 我需要' '分别对它们中的每一个进行工作 - 所以我无法仅使用 jquery 选择器来检测 DOM 元素而没有技巧......)

Just by this (in any method in "methods"):
就这样(在“方法”中的任何方法中):
let domElement = this.$el;
:)
:)
But remember this is valid as long as your component is not a Fragment Instancei.e. it has a single root HTML tag
但请记住,只要您的组件不是Fragment 实例,即它具有单个根 HTML 标记,这就是有效的
