所以我正在为一个网络应用程序创建一个注册页面。但是,我无法通过提交按钮重定向到确认页面。注册servlet接收用户的信息,所有确认servlet只显示用户的名字并打印出来#34; Welcome(用户名)"
这是我的代码:
注册servlet
Sub Pi()
Dim enne As Variant, phi As Variant
phi = CDec(1)
enne = 100000000
For i = 0 To enne
phi = 6 + ((2 * enne + 1) * (2 * enne + 1)) / phi
enne = enne - 1
Next
phi = phi - 3
Debug.Print " 3.14159265358979323846264338327950288419716"
Debug.Print phi
End Sub
确认servlet

如果您想对post方法执行某些操作,则应将method="post"
添加到form
标记。
