Inno setup 我需要inno设置自定义页面中的帮助

在Inno设置中，我创建了一个带有以下代码的自定义页面，其中有3个文本框

现在我想验证自定义表单上的文本框“下一步”按钮。如果用户在text.text='2121212'中输入了文本，则仅启用“下一步”按钮

    ; This script shows how to insert custom wizard pages into Setup and how to handle
    ; these pages. Furthermore it shows how to 'communicate' between the [Code] section
    ; and the regular Inno Setup sections using {code:...} constants. Finally it shows
    ; how to customize the settings text on the 'Ready To Install' page.

    begin
    If CurPageID = Page.ID Then
      WizardForm.NextButton.Enabled := false;
    end;

    end.

写入时，它会检查第三个文本框中的“2121212”值。如果希望在第一个或第二个框中显示，则需要为相应的编辑框添加OnChange事件处理程序
