首先,我是网页设计的新手,只懂HTML和CSS。

我希望能够在不离开用户所在的页面的情况下发送联系表单消息。我怎样才能做到这一点?

请非常具体,因为我对这一切都不熟悉。

HTML

<html>
<head>
</head>

<body>

<a href="#openModal">Email Us</a>



<div id="openModal" class="modalDialog">
    <div>
        <a href="#close" title="Close" class="close">X</a>
        <h2>Contact Us</h2>
        <section class="body">

    <form id="myForm" name="contactform" method="post" action="send_form_email.php">

<table width="450px">

PHP

            <?php

        // EDIT THE 2 LINES BELOW AS REQUIRED

        $email_to = "example@server.com";

        $email_subject = "New CBWC Contact Form Message";





        function died($error) {

            // your error code can go here

            echo "We are very sorry, but there were error(s) found with the form you submitted. ";

            echo "These errors appear below.<br /><br />";

            echo $error."<br /><br />";

            echo "Please go back and fix these errors.<br /><br />";

            die();

        }

        if(!isset($_POST['first_name']) ||

      }

      if(strlen($comments) < 2) {

      }

      if(strlen($error_message) > 0) {

        function clean_string($string) {

    // create email headers

    $headers = 'From: '.$email_from."\r\n".

    'Reply-To: '.$email_from."\r\n" .

    'X-Mailer: PHP/' . phpversion();

    @mail($email_to, $email_subject, $email_message, $headers);  

    ?>

    <?php

只要提供代码,我就可以使用任何类型的语言。

这是我到目前为止所做的一个例子。 (它不是成品:) http://cbwconline.com/modal%201.html

查看Ajax请求。

使用Ajax,您可以在后台发送HTTP请求,也可以异步发送(保持异步!很多人都忘记异步是Ajax的一个重要方面)

我建议你使用一个名为jQuery的库来使你的Ajax请求更容易:

假设您的PHP文件名为checker.php,您可以通过jQuery向它发送Ajax请求,如下所示:

$.ajax({
  url: "checker.php",
  type: "POST",
  data: {/*Fill in data*/},
  success: function(resp){
    // Message (error or success)
    $("#response").html(resp)
  }
});

当用户单击表单上的提交时,可能会触发此操作。您可以阻止表单使用整齐的小event.preventDefault()方法自动发出HTTP请求。因此,举例来说,让我们这样做:

$("#myForm").on("submit", function(event){
  event.preventDefault();
  // Perform Ajax request:
  $.ajax({
    url: "checker.php",
    type: "POST",
    data: {/*Fill in data*/},
    success: function(resp){
      // Message (error or success)
      $("#response").html(resp)
    }
  });
});

要记住的事情:

  1. jQuery是基于JavaScript构建的,因此jQuery中显示的任何内容都可以在无库的JavaScript中完成
  2. Ajax请求异步,让它们保持异步。
  3. 我轻松地将此代码基于您的代码。您可能需要调整一下才能适应您的设置。
