You need to encode and decode with JSON

var link = document.getElementsByTagName('a')[0];
link.addEventListener('click', function(){
    // this could also be done with location.hash = JSON.stringify(...);
    var param = JSON.stringify(['your', 'array']),
        href = '#'+this.getAttribute('href');
    href += param;
    location.href = href;
}, false);


// make string an object/array again
var obj = JSON.parse(window.location.hash.substr(1));
