Question

在我的网站上使用HTML，Bootstrap，Php我创建了一个联系我们表单。表单工作正常，我能够得到消息。但问题是，在点击提交按钮后，会打开一个新页面，以及＃34;感谢您的消息＆＃34;。您能否指导我如何在提交按钮下方显示感谢信息。我的代码如下所述。

Answer 1

您需要阻止提交

表单的默认操作

<强>的jQuery

$('#contact-form').submit(function (event) {
   //prevent the default action, which is to submit the form
   event.preventDefault();
   //post your from below using ajax
})

Answer 2

您的通知消息显示在此部分代码中：

<div class="messages"></div>

您只需将此部分代码移至底部即可。像这样：
