Question

test
test


        
      

Answer 1

You can use the sort function to do it.

function arrayify(obj){
    return [].slice.call(null,obj);
}
var all = arrayify(document.querySelectorAll('div[id]'));
var max = all.sort().pop();
var min = all.sort().reverse().pop();

This is way easier that using jQuery
