@编辑2,
我认为问题源于传递参数。
<br />
<b>Warning</b>: mysqli_connect(): (HY000/2002): Connection refused in <b>/opt/lampp/htdocs/ch1/saveEmail.php</b> on line <b>12</b><br />
Failed to connect to MySQL: Connection refused<br />
<b>Warning</b>: mysqli_query() expects parameter 1 to be mysqli, bool given in <b>/opt/lampp/htdocs/ch1/saveEmail.php</b> on line <b>30</b><br />
<br />
<b>Warning</b>: mysqli_close() expects parameter 1 to be mysqli, bool given in <b>/opt/lampp/htdocs/ch1/saveEmail.php</b> on line <b>41</b><br />
@Edit，如果我禁用doRecord 方法并将随机数分配给$retVal，我可以从控制台看到它的值。我认为问题出在函数的主体上。
我正在尝试将字段输入的信息保存到 MySQL 数据库中。但是我什至看不到 exit(json_encode(array("response"=> $response))); 或 exit(json_encode(array("response"=> $response))) 的结果是什么未输入")));.我确定数据库有效，我测试过。此外，按钮 onclick 有效，但仅此而已。怎么了？

最佳答案
您的 saveEmail.php 文件中的引号似乎不正确。如果使用代码突出显示，则更容易看到。而不是:
exit(json_encode(array("response" => "not entered”)));
尝试:
exit(json_encode(array("response" => "not entered")));
编辑:
要查看哪种错误会阻止您的 AJAX 调用，请将这些调用行放在 saveEmail.php 的开头:
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
然后暂时将您的 ajax 调用更改为如下所示:
$.ajax({
url: 'saveEmail.php',
method: 'POST',
data: {
name: name.val(),
email: email.val(),
subject: subject.val(),
body: body.val(),
cron: cron.val()
}, success: function (response) {
console.log(response);
} });
