问题
我会尝试尽可能多地包含尽可能多的信息而不会使事情变得复杂，但我有一个问题，即当我提交表单时，页面会刷新，从而关闭带有表单的选项卡。然后，用户需要再次单击选项卡以查看反馈。
背景信息。
我有一个使用JavaScript打开和关闭“标签”（div）的网页，在其中一个标签上我有一个表格，用户将数据输入到php脚本，然后将数据发送到电子邮件地址然后重定向回原始页面。但是，当脚本重定向回页面时，选项卡将关闭，从而使用户重新单击选项卡以再次打开它以查看脚本的自动反馈。
我检查了什么
我已经检查过，并不是导致刷新的重定向，因为当表单POST自身时它仍然会发生。
有没有人有任何想法？
以下是表单的HTML，位于查询“标签”中。
<div class='content one'>
<div id="contact-form" class="clearfix">

提交表单时，您正在发出POST请求。默认情况下，POST请求通过浏览器发送到服务器的HTTP请求，因此浏览器需要加载导致站点刷新的新数据。
如果您希望浏览器不刷新，那么您需要在客户端使用Javascript执行AJAX请求。您可以使用jQuery来完成此任务。

试试这个
$('form').submit(function(e)
{
e.preventDefault();
})

谢谢@saman和@gpopoteur，
你的答案很棒并且有效，只是没有在我的测试服务器上工作。
这最终会起作用。
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js" type="text/javascript"></script><script>
$('#form1').submit(function(e)
{
event.preventDefault();
$.ajax({
type : 'POST',
url : 'process.php',
data : $(this).serialize(),
success : function(response) {
}
});
});
我找到的是虽然脚本没有返回任何内容。 E.我是否有任何验证信息或返回的数据？没有太大的问题，我会创造一个解决方案。再次感谢
