我在我的网站上翻了一番选择箱子。 不需要这个领域。 如果用户意外地作出选择,是否容易让用户重新确定外地无效?

<option value="1" >option 1</option>
<option value="2" >option 2</option>
<option value="3" >option 3</option>
</select>
<input type="button" value="reset" id="resetbtn" />
js:
$( #resetbtn ).click(function(){
$( select#select ).prepend( <option selected="selected" value="null" class="null"></option> );
});
$( select#select ).bind( focus click mouseup ,function(){
$(this).find( option.null ).remove();
});
