Question

我之前只看到过另外一个类似的问题（this one）而且我不知道如何将它应用到我的页面。我是网络开发的新手，因此我使用this template作为联系表单。您可以在此处查看我的联系页面：http://mikeyaworski.com/contact_files/

问题是当您提交邮件时页面会重新加载（我认为）。我正在使用window.onbeforeunload功能在用户离开页面时提醒用户。但是当他们按下提交时，警报就会出现，因为他们是＃34;离开页面＆＃34;显然。那不是我想要的。我希望页面不重新加载，因此不应弹出警报。

旁注：提交后，字段会更改大小。有谁知道为什么？

这不是我的代码，因此我不确定是什么让网页重新加载以及如何修复它。

这是索引页面（我认为相关部分）：

<?PHP
require_once("./include/fgcontactform.php");
$formproc = new FGContactForm();
$formproc->AddRecipient('mail@mikeyaworski.com'); //<<---Put your email address here
$formproc->SetFormRandomKey('CnRrspl1FyEylUj');

if(isset($_POST['submitted'])) {
    if($formproc->ProcessForm()) {
        echo "<script type='text/javascript'>alert('Sent!');</script>";
    }
}

?>

我认为它与$formproc = new FGContactForm();有关。因此，如果您需要查看文件fgcontactform.php中的函数，请告诉我。

Answer 1

<强>已更新

<input type="submit" name="Submit" value="Submit" onclick="window.onbeforeunload = null;">

如果您点击提交，则将处理程序window.onbeforeunload设置为null。

Answer 2

所有表单都会重新加载页面。如果你想在没有重新加载的情况下发布数据（由于安全性而没有建议），你必须研究AJAX。

在联系表格上提交时，请勿“离开此页面”
