button component m.mount

This is an example showing a generic button component, that can be used to render buttons in different types, colors, floats, and more. It shows also, that implementing a custom compononent in Mithril.js is really simple.

Live Example #

JavaScript #

const Button = {
  view: ({attrs: {type, text, onclick, color, disabled, left}}) =>
    m('button', {
      class: color || 'grey',
      type:  type  || 'button',
      disabled,
      onclick,
      style: 'float: ' + (left ? 'none' : 'right')
    }, text)
}

const app = {
  view: () =>
    m('div',
      m(Button, {text: 'bye',   color: 'blue', left: true}),
      m(Button, {text: 'hello', color: 'red',  left: true, onclick: () => p('click!')}),
      m(Button, {text: 'error', color: 'green'}),
      m(Button, {text: 'test'})
    )
}

m.mount(document.body, app)

CSS #

button {
   height: 36px;
   margin-left: 10px;
   padding: 0 16px;
   border: 0;
   border-radius: 4px;
   text-transform: uppercase;
   font-weight: 500px;
   font-size: 14px;
   min-width: 64dp;
   cursor: pointer;
   outline: none
}

.grey {
  background-color: #f1f1f1;
  color: #616161
}

.grey:hover {
  background-color: #ccc
}

.blue {
  background-color: #349cfb;
  color: #fff
}

.blue:hover {
  background-color: #2c83d4
}

.red {
  background-color: #eb2024;
  color: #fff
}

.red:hover {
  background-color: #b6191c
}

.green {
  background-color: #33b679;
  color: #fff
}

.green:hover {
  background-color: #2a9928
}

As a prerequisite for this snippet, the latest version of Mithril.js framework is required. Beginners should have no problems following this example, that simply shows some basic recipies.

In this code sample Mithril.js' m.mount API method is use, besides the basic hyperscript function m().
