Javascript building element reference node list

Question

How can i build a nodelist, which is reference to the selected node? Example document.querySelectorAll(\'tr\') returns a nodelist contains all the tr element no

Answer 1

If you don't want to move things around in the DOM, don't use the methods that move things around!

var nl = new Array();
var el = document.querySelectorAll('tr');
for ( var a = 0; a < 2 && a < el.length; a++)
{
    nl.push(el[a]);
}
