Usage

Add go-native.js and go-native.ie8.js to your page.

<!--[if (lt IE 9)]>
  <script src="path/to/go-native.ie8.js"></script>
<![endif]-->
<script src="path/to/go-native.js"></script>

DOM.ready

gn.ready(function () {
  // do something
  // on DOM ready
});

isInViewport

var el = document.querySelector('.element');
if (gn.isInViewport(el)) {
  // when element is in viewport
  // do something
}

indexOf

var index,
    list = document.querySelectorAll('.list > li'),
    current = document.querySelector('.current');

index = gn.indexOf(list, current);

getOuterWidth

// content + padding + border + margin
var box = document.querySelector('.box'),
    boxWidth = gn.getOuterWidth(box);

getOuterHeight

// content + padding + border + margin
var box = document.querySelector('.box'),
    boxHeight = gn.getOuterHeight(box);

getOffsetLeft

var box = document.querySelector('.box'),
    boxLeft = gn.getOffsetLeft(box);

getOffsetTop

var box = document.querySelector('.box'),
    boxTop = gn.getOffsetTop(box);

getSupportedProp

var transitionDuration = gn.getSupportedProp(['transitionDuration', 'WebkitTransitionDuration', 'MozTransitionDuration', 'OTransitionDuration']);
console.log(transitionDuration);

getClosest

var element = document.querySelector('.element'),
    red = gn.getClosest(element, '.red');

getParents

var element = document.querySelector('.element'),
    red = gn.getParents(element, '.red');

getParentsUntil

getSiblings

var element = document.querySelector('.element'),
    siblings = gn.getSiblings(element);

createElement

var el = gn.createElement({
  tagName: 'div',
  id: 'foo',
  className: 'foo',
  children: [{
   tagName: 'div',
   html: '<b>Hello, creatElement</b>',
   attributes: {
     'am-button': 'primary'
   }
  }]
});

append

var container = document.querySelector('.container');
gn.append(container, '<li>Peach</li>');
gn.append(container, el);

prepend

var container = document.querySelector('.container');
gn.prepend(container, '<li>Pear</li>');
gn.prepend(container, el);

wrap

var p = doc.querySelectorAll('p'),
    div = doc.createElement('div');
gn.wrap(p, div);

wrapAll

var p = doc.querySelectorAll('p'),
    div = doc.createElement('div');
gn.wrapAll(p, div);

unwrap

var container = doc.querySelectorAll('.container');
gn.unwrap(container);
