  2.   

    可以改变元素的innerHTML属性的值来实现这种效果:
    <script>
      //spanType 为一span标签的ID
        spanType.innerHTML="<Select><option>...</option></Select>"  
    </script>
      

  3.   

    把地名改为车名就行。

    先对,三位表示感谢,可是我的意思是两个下拉列表框的值,全部是从数据库里取出来的。
    当第一个下拉列表框onchange 时,第二个下拉列表框的值,也进行改变(也是从数据库里进行取值).期待中......................
      

  5.   

    把第二个下拉框放在iframe里面,每次第一个下拉列表onchange的时候,将选择的值作为参数传递给这个iframe里的文件,然后加载此文件即可:)

    楼上的兄弟,请教在javascript 里可以直接用asp 的东西吗?
    如你写的<% %>
