Removing A Option From Dropdownlist Item With Jquery

I have a situation where in some cases a dropdownlist can contain a default value that is not selectable, once another value is changed, the default value should no longer be an op

Solution 1:

Assuming your HTML is like this

<select id="dd"class="valueSkippedHyperSwap"> 
    <option value="^">None</option>
    <option value="1">One</option>
    <option value="2">Two</option>    
</select>

The below script should remove item with value ^ if any other options are selected

$(function(){

    $('.valueSkippedHyperSwap').change(function () {
       var item=$(this);
      if(item.val()!="^")
      {
        item.find("option[value='^']").remove();
      }
    });            

});
