用select控件怎么触发不了onserverchange事件?
<select name= "ss " id= "ss " runat= "server " onserverchange= "ss_change ">
<option value= "1 "> 1 </option>
<option value= "2 "> 2 </option>
</select>
这么写对吗?怎么就是触发不了后台代码呢?
------解决方案--------------------不对.
------解决方案--------------------还设置postback为true
------解决方案-------------------- <asp:DropDownList ID= "DropDownList1 " OnSelectedIndexChanged= "chg " runat= "server " AutoPostBack= "true ">
<asp:ListItem Value= "1 "> 1 </asp:ListItem>
<asp:ListItem Value= "2 "> 2 </asp:ListItem>
</asp:DropDownList>
------解决方案--------------------嗯,楼上的都说完了
------解决方案--------------------要用服务器控制,HTML控件不行的, 用asp:DropDownList 楼上的说的很~~~清楚啦
