vdom-query

Traverses and manipulates virtual-dom trees.

Implements a subset of the jQuery API.

Example

var h = require('virtual-dom/h');
var $ = require('vdom-query');

function render() {
  return h('.top', h('.banana'));
}

var vdom = render();
$(vdom).find('.banana').first().attr('class') //-> banana

API

Finding elements in a virtual dom

var $ = require('vdom-query');
$(vdom).find('your-selector')

• vdom - a virtual DOM fragment.

The resulting vdom-query object represents a set of elements, which can be manipulated to produce new sets. Every set can extract data or interact with its matching elements.

Traversing the dom to find elements is deferred until it is required, rather than as the query is being constructed. The dom is re-rendered before any traversal.
