主题：[求助]获取不到值，怎么处理？

我这样测试没问题

Select Case e.Path
    Case "test.htm", ""
        Dim wb As new WeUI
        If e.PostValues.Count = 0 Then
            wb.AddForm("","form24","/test.htm")
            With wb.AddInputGroup("form24","ipg2","<a style='color: #3CB371;'>填空题回答区:</a>")
                .AddInput("xmA","第1个空","text").Placeholder = "请输入第一个答案"
                .AddInput("xmB","第2个空","text").Placeholder = "请输入第二个答案"
                .AddInput("xmC","第3个空","text").Placeholder = "请输入第三个答案"
            End With
            With wb.AddButtonGroup("form24","btngrp1", False)
                .Add("btn4", "提交", "submit") '提交
               
               
            End With
           
        Else
           
            MessageBox.Show(e.PostValues("xmA"))  '获取录入值为空白怎么处理
        End If
        e.WriteString(wb.Build) '生成网页
End Select
