1.Include Dependencies:
<script type="text/javascript" charset="utf-8"
        src="http://yui.yahooapis.com/3.1.1/build/yui/yui-min.js">
</script>

2.The YUI Instance:
YUI().use('node', function(Y) {
 
    // Node available, and ready for use.
 
});

3.Getting a Node:
YUI().use('node', function(Y) {
    var node1 = Y.one('#main');
    var node2 = Y.one(document.body);
});

4.Using Node:
  4.1Accessing Node Properties:
  YUI().use('node', function(Y) {
    var node = Y.one('#foo');
    var parent = node.get('parentNode'); // Node instance
 
    var html = 'I am "' + node.get('id') + '".';
    html += 'My parent is "' + parent.get('id') + '"';
 
    node.set('innerHTML', html);
});

  4.2DOM Events
  YUI().use('node', function(Y) {
    Y.one('#demo').on('click', function(e) {
        e.preventDefault();
        alert('event: ' + e.type + ' target: ' + e.target.get('tagName')); 
    });
}); 

  4.3DOM Methods
  YUI().use('node', function(Y) {
    var node = Y.one('#demo');
    var node2 = node.appendChild(Y.one('#foo p'));
    node2.addClass('bar');
});

  4.4Using NodeList
  YUI().use('node', function(Y) {
    Y.all('#demo li').addClass('bar');
});

  YUI().use('node', function(Y) {
    Y.one('#demo').get('children').addClass('bar');
});

  4.5Node Queries
  YUI().use('node', function(Y) {
    var node = Y.one('#demo');
 
    var node2 = node.one('p');
    if (node2) { // might be null
        node2.addClass('bar'); // adds "bar" to the first paragraph descendant of #demo
    }
 
    node.all('p').addClass('bar'); // adds "bar" to all paragraph descendants of #demo
 
    if (node.test('.foo.bar')) { // "if node has both foo and bar classNames"
        node.removeClass('bar');
    }
}); 

   4.6ARIA Support
   YUI().use('node', function(Y) {
    var node = Y.one('#toolbar').set('role', 'toolbar');
});

YUI().use('node', function(Y) {
	Y.one('#rootmenu').set('role', 'menubar').all('.menu').setAttrs({ role: 'menu', 'aria-hidden': true });
});
