jquery和javaScript 清空 select下拉框里的所有选项

javaScript的写法

<select id="area">    <option>11</option>     <option>22</option>      <option>33</option></select>

<script>var area= document.getElementById("area");area.innerHTML = "";for(var i=0;i<area.childNodes.length;i++){area.removeChild(area.options[0]);area.remove(0);area.options[0] = null;}</script>

jquery的写法

$("#area").html("");$("#area").find("option").remove();或者$("#area").empty();
