分享javascript: alert window
以下为完整代码：
当数据库中没有所输入的login时，则alert window报错。
问题是：我只想它报错一次，而它却弹出报错两次。请问有何办法解决。

把
<a href="javascript:(0)" onclick="return getname(this.form)" class="unnamed5" >下一步
中的javascript:(0)改为javascript:null或#试试
<a href="javascript:(0)" onclick="return getname(this.form)" class="unnamed5" >下一步

如果是按“下一步”，则alert两次，如果是按浏览器上的“刷新”，则alert一次。
