React Refs in Mithril.js

26 October 2021 by stephanhoyer

Level: beginner • Mithril.js Version: latest

dom m.mount oncreate react vnode

This example shows how to access dom nodes of a component, much like Reacts refs.

Live Example #

JavaScript #

function findRef(dom, ref) {
  return dom.matches(`[ref=${ref}]`) ? dom : dom.querySelector(`[ref=${ref}]`)
}

const MyComponent = {
  oncreate(vnode) {
    const title = findRef(vnode.dom, 'title')
    title.style.color = 'red'
  },
  view() {
     return m('h1', { ref: 'title' }, 'abc')
  }
}

m.mount(document.body, MyComponent)

The snippet is using the most current version of Mithril.js framework. It is aimed at beginners and shows some basic recipes.

In addition to the Mithril.js hyperscript function m(), here we can see an example of Mithril.js' m.mount API method. It also shows, how Mithril.js' lifecycle methods can be used. This can be seen here by using the oncreate hook. In this example we can also see the usecase of Vnodes (virtual DOM nodes) which is a JavaScript data structure that describes a DOM tree.
