Live Example #

JavaScript #

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

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

  return {
    view: () => [
      m(getmsg, {
        msg,
        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.
