To refresh select box using jQuery, refer to the code below:-

// Assuming there is a select box with ID = myselectbox

// this will clear all select box item
$('#myselectbox').children().remove().end();

var s = document.getElementById('myselectbox');

// add item to select box 
s.options[s.options.length] = new Option('', '');
s.options[s.options.length] = new Option('Label 1 here', 'value 1 here');
s.options[s.options.length] = new Option('Label 2 here', 'value 2 here');
