所以在我使用了新的 JavaScript 之后。这是所有的代码。请记住，他们仍然缺少顶部身体。没有把它放进去，因为它可能与我的问题无关。

       <script type="text/javascript">
        function Confirm(form){
        alert("Thank you for your feedback.");
        form.submit();
        window.location.href = "/index.php";
        }
       </script>

由于某种原因，它不想在添加这种 JavaScript (window.location.href = "/index.php";) 时将我的数据加载到 MySQL 中。

Answer 1

当您执行form.submit() 时，您告诉表单执行表单操作属性中所述的操作。因此它将自动重定向到那里设置的任何内容。

例子：

<form action="submit.php" method="POST">

在用户关闭警报消息后，您的代码会将用户重定向到submit.php。当重定向到submit.php 时，您必须从那里处理重定向。

当然，除非您使用 AJAX 发布表单或类似的东西。

然后你可以添加：

window.location.href = "/index.html"; 

虽然在这种情况下，最好将它放在 AJAX 调用的成功函数中：

function Confirm(form){alert("Thank you for your feedback.");form.submit(); window.location.href = "/index.html";}

Answer 2

如果你想在 JavaScript 中进行重定向，它会是：

window.location.replace("yourwebsite.com/index.php");

如果你想用 PHP 来做，那就是：

header('Location:index.php');

Answer 3

你可以简单地使用

function Confirm(form){alert("Thank you for your feedback.");form.submit();
window.location = "location";
}
