Question

当我选择一个图标时，只有文本显示在我的选择框中，而不是图标：

$(document).ready(function(){
  $("#social").select2({
   templateResult: formatState
  });
 });
 
 function formatState (state) {
  if (!state.id) { return state.text; }
  var $state = $(
   '<span ><i class="fa fa-'+ state.id +'"> ' + state.text + '</span>'
  );
  return $state;
 }
