JS rolling link - using linkify - how to target a specific class?

Question

I'm using this code in my website http://jsfiddle.net/hakim/Ht6Ym/

var supports3DTransforms =  document.body.style['webkitPerspective'] !== undefined || 
                            document.body.style['MozPerspective'] !== undefined;

function linkify( selector ) {
  if( supports3DTransforms ) {

    var nodes = document.querySelectorAll( selector );

    for( var i = 0, len = nodes.length; i < len; i++ ) {
        var node = nodes[i];

        if( !node.className || !node.className.match( /roll/g ) ) {
            node.className += ' roll';
            node.innerHTML = '<span data-title="'+ node.text +'">' + node.innerHTML + '</span>';
        }
    };
  }
}

linkify( 'a' );

I'm not very good at JS (fairly new) but at the end it targets all <'a'> tags:

linkify( 'a' );

However this is changing all links to this rollover effect. Is there anyway that I can target a specific class - lets call it .rolling - so that only the header is affected and not the other links?

Answer 1

You can do this

linkify( 'h1 a' );

DEMO

if you want to select by class you can use .selector

linkify('a.myClass');
