莫代尔：是的，
自动打开：错误，
按钮：{
好的：函数（）{
$（此）.dialog（“关闭”）；

错误，您没有链接到帐户的电子邮件地址
您不能请求此报告
上述方法工作正常。它对我不起作用的原因是，我的sql脚本正在返回一个结果，而我希望它什么也不返回
当没有返回任何内容时，我的If语句工作正常
这是全部的

你能描述一下你遇到的问题吗？即使有电子邮件，对话框是否仍在打开？您是否从未收到电子邮件？对话框是否从未打开？我在开始时使用的代码是正确的，发现没有电子邮件地址时返回的NULL实际上是一个空格“”，我正在检查NULL。。已将所有“”电子邮件地址更新为空，并且工作正常，这让我头疼。@user3339240您好，欢迎使用SO。我很高兴你找到了你问题的答案，请你把它作为一个答案贴出来，并标记为接受（见）。这种做法是积极鼓励的，而且它意味着问题不会出现在未回答的列表中。@user3339240您也没有发布相关代码，看起来问题出在SQL上？
