how to skip non selected select option

[takeAction]

I am using FormDataJson.toJson("#searchForm", {skipEmpty: true}), but I found that for select option:

<select name="gender">
	<option value="" selected></option>
	<option value="0" >Male</option>
	<option value="1" >Female</option>
</select>

if there is no valid option selected(that is Male or Female in this case), FormDataJson.toJson("#searchForm", {skipEmpty: true}) still return gender with null, what I suppose is to skip gender. I tried to change <option value="" selected></option> to <option ></option>, still not work.

how can I skip non selected select element?
