联系表单将重点放在提交上

Question

我有一个 bootstrap 一页最后有一个联系表。我希望在提交时将重点放在该部分而不是页面的开头。 因此，如果消息已发送，用户将看到 OK 消息，否则他们将看到错误。

这是我的代码。 Html

<section id="contact"> 
      <div class="container">
        <div class="row">
          <div class="col-md-12">
            <h2 class="heading">Contact</h2>
            <div class="row">
              <div class="col-md-12">

                <?php
                  $to = 'mail@mail.mm';
                  $subject = 'Enquiry from the website';
                  $contact_submitted = 'Your message was submitted and will be responded to as soon as possible. Thank you for contacting us.';

                  function email_is_valid($email) {
                    return preg_match('/^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i',$email);
                  }
                  if (!email_is_valid($to)) {
                    echo '<p style="color: red;">You must set-up a valid (to) email address before this contact page will work.</p>';
                  }

在html中使用AJAX调用php。
