Answer 1

Assuming that each dropdown has a unique ID specified: <select id="dropdown1"> etc:

var dd1 = document.getElementById('dropdown1');
var dd2 = document.getElementById('dropdown2');

if(dd1[dd1.selectedIndex].value == dd2[dd2.selectedIndex].value)
{
 alert("Dropdown 2 is the same value as dropdown1 !!!");
}
