HyperScript

Create HyperText with JavaScript.

Example

var h = require('hyperscript')
h('div#page',
  h('div#header',
    h('h1.classy', 'h', { style: {'background-color': '#22f'} })),
  h('div#menu', { style: {'background-color': '#2f2'} },
    h('ul',
      h('li', 'one'),
      h('li', 'two'),
      h('li', 'three'))),
    h('h2', 'content title',  { style: {'background-color': '#f22'} }),
    h('p', 
      "so it's just like a templating engine,\n",
      "but easy to use inline with javascript\n"),
    h('p', 
      "the intension is for this to be used to create\n",
      "reusable, interactive html widgets. "))

h (tag, attrs, [text?, Elements?,...])

Create an HTMLElement. first argument must be the tag name.

classes & id

If the tag name is of form name.class1.class2#id that is a short cut for setting the class and id.

attributes

If an {} object is passed in, it's values will be used to set attributes.

var h = require('hyperscript')
h('a', {href: 'https://npm.im/hyperscript'}, 'hyperscript')

events

If an attribute is a function, then it will be registered as an event listener.

var h = require('hyperscript')
h('a', {href: '#', 
  onclick: function (e) {
    alert('you are 1,000,000th visitor!')
    e.preventDefault()
  }
}, 'click here to win a prize')

styles

If an attribute has a style property, then that will be handled specially.

var h = require('hyperscript')
h('h1.fun', {style: {'font-family': 'Comic Sans MS'}}, 'Happy Birthday!')

You may pass in attributes in multiple positions, it's no problem!

children - string

If an argument is a string, a TextNode is created in that position.

children - HTMLElement

If a argument is a Node (or HTMLElement), for example, the return value of a call to h thats cool too.

children - null.

This is just ignored.

children - Array

Each item in the array is treated like a ordinary child. (string or HTMLElement) this is uesful when you want to iterate over an object:

var h = require('hyperscript')
var obj = {
  a: 'Apple',
  b: 'Banana',
  c: 'Cherry',
  d: 'Durian',
  e: 'Elder Berry'
}
h('table',
  h('tr', h('th', 'letter'), h('th', 'fruit')),
  Object.keys(obj).map(function (k) {
    return h('tr', 
      h('th', k),
      h('td', obj[k])
    )
  })
)
