Answer 1

如果你使用Javascript，那就非常简单了。这样做，

var countries = {"BD": "Bangladesh", "BE": "Belgium", "BF": "Burkina Faso", "BG": "Bulgaria"};
var selectHTML='';

for (var key in countries)
 {
     selectHTML +='<option value="'+key+'">'+countries[key]+'</option>';
 }
 
 document.getElementById('countries').innerHTML = selectHTML;

<div id="select_box_wrapper">
  <select id="countries"></select>
</div>
