There's nothing "built-in" to do that, but you can use the each() method to
perform some logic on each match found:
$("option:selected", oSelect).each(
function (i){
// "this" is a reference to the DOM element, not jQuery
object
// "i" is the current array position
// if the value attribute of the tag is empty, remove the
item
if( this.value.length == 0 ) $(this).remove();
}
);
Now the above example would remove any value selected who's <option />
element's "value" attribute was empty. You need to build in additional
checking to see if it was the first child of the parent <select /> element.
