如何动态添加select控件内容，并绑定相应的value值
现在有select控件，id为pid：
<td noWrap><select id="pid" style="WIDTH: 100px" runat="server"
<option selected></option>
</select> </td>
想动态的将一个数组的内容添加到其中作为下拉项
var a=new Array("中国","美国","英国","朝鲜","韩国");
var b=new Array("0","1","2","3","4");
怎样将这些值插入其中，并且使b数组中的值作为它的各项的value值？
用javascript

如果第二次执行如何清除第一次的结果，就是将pid中的所有项删除然后在重新绑定？Top
