Answer 1

发现差异：

<form id="<?php echo $row["id"] ?>" name="" method="post" onsubmit[..snip...]
                                                   ^^^^^^

if (isset($_GET["gcmregid"]) && isset($_GET["message"])) {
           ^^^^^                       ^^^^

另外，你的HTML被破坏了...... <p4>？从什么时候开始有不同种类的段落标签？

Answer 2

 success: function(data, textStatus, xhr) {
                          $('.txt_message').val(data);
                    },

不会做功能，只刷新
