问题：如何在我单击步骤2中的提交按钮后自动关闭弹出窗口。单击“提交”按钮后，我无法自动关闭弹出窗口。如果您在弹出窗口内部，您可以简单地调用

window.close（）关闭它。把它放在哪里取决于你想什么时候关闭它。例如，如果要在服务器端处理后关闭它，可以向服务器端代码中添加以下内容：

echo "<script type='text/javascript'>window.close();</script>"

echo“window.close（）；”
我应该把echo脚本放在我的弹出窗口的什么地方？旁注，看在上帝的份上，使用
，每次你制作所有CAPS HTML标签时，上帝都会狠狠地屠杀一只小狗。
