对于普通DOM元素，findDOMNode vs getElementById [英] findDOMNode vs getElementById for plain DOM elements

问题描述

我不太确定这个问题有一个真正的答案，但我想知道在React应用程序中使用

I'm not quite sure there's a real answer to this question but I was wondering if it's better to find regular DOM elements in a React app by using

a找到常规DOM元素是否更好。 refs和ReactDOM.findDOMNode

a. refs and ReactDOM.findDOMNode

或

b。 plain old document.getElementById

b. plain old document.getElementById

推荐答案

我更喜欢refs的模式，因为它会鼓励你不要为元素添加ID，因此允许您在单个页面上使用react组件的多个实例。 react中的ref特性将为您提供由该组件的特定实例呈现的元素，而不是来自其任何重复渲染的元素。

I would prefer the pattern of refs because it would encourage you not to add IDs to elements and therefore allow you to use multiple instances of a react component on a single page. The ref feature in react will get you the element rendered by that specific instance of the component, and not an element from any duplicate renderings of it.
