How to remove options from select using jQuery

We  can sort an array using this method:

1. This is the select (HTML):

   <select name="selectBox" id="selectBox">
       <option value="option1">option1</option>
       <option value="option2">option2</option>
       <option value="option3">option3</option>
       <option value="option4">option4</option>	
   </select>

2. How to remove the items. Just do:

   //Deleting all the items with value equals to 'X':
   $("#selectBox option[value='X']").each(function() {
       $(this).remove();
   });

   //Or:
   $("#selectBox option[value='X']").remove();
