推荐答案

您修复了代码，以使其显示正确的内容.不知道还有什么要说的.当您不发布任何代码而只告诉我们您要执行的代码时，您期望得到什么样的答案?我什至不知道如何诊断为什么您的代码为什么不看它，或者您在哪里显示邮件并想显示文本框.

You fix the code so that it shows the right thing. Not sure what else to say. What sort of answer were you expecting, when you post no code and just tell us what you wnat your code to do ? I don''t know how to even diagnose why your code is doing that without seeing it, or where you''re showing mail and want to show a textbox.
