Live Example


Type Name URL


const getmsg = {
  view: v =>
    m("input", {
      value: v.attrs.msg,
      oninput: e => v.attrs.change(

const app = () => {
  let msg = 'start'

  return {
    view: () => [
      m(getmsg, {
        change: value => {msg = value}
      m('h1', msg)

m.mount(document.body, app)

The snippet requires the latest version of Mithril.js framework. It is ideal for beginners showing some basic recipes.

In this example we can see an example of Mithril.js' m.mount API method, besides it core m() hyperscript function.
