使用 Ajax 和 jQuery 发送邮件（邮件到 php Post 方法）答案

【问题标题】：send mail (mail to php Post method) using Ajax and jQuery使用 Ajax 和 jQuery 发送邮件（邮件到 php Post 方法）
【发布时间】：2016-11-25 05:22:00
【问题描述】：

我通过执行一个 PHP 函数，我的 index.html 从我的 html 页面发送邮件：

  <form method="POST" action="sendmail.php" >
 <input type="text" name="sender_name" placeholder="Name" required="">
 <input type="text" name="sender_email" placeholder="Email" required="">
 <input type="text" name="subject" placeholder="Subject" required="">
 <textarea placeholder="Message" name="message" required=""></textarea>
  <input type="submit" name="send" value="SEND">

    </form>

我的 sendmail.php：

<?php
if($_POST['send'] == 'SEND'){

$to      = 'queries@mydomain.com';
$subject = $_POST['subject']; 
$message = $_POST['message']; 
$headers = "From: ".$_POST['sender_nam‌e']." <".$_POST['sender_em‌ail‌'].">\r\n"; $headers = "Reply-To: ".$_POST['sender_ema‌il‌']."\r\n"; 
$headers = "Content-type: text/html; charset=iso-8859-1\r\n";
'X-Mailer: PHP/' . phpversion();
mail($to, $subject, $message, $headers);
}
?>

以上工作正常，但也离开当前页面

我必须使用 Ajax 和 jQuery？到目前为止，我对他们一无所知：

////in my index.html
<button type="button">send mail</button>
<p></p>
<script type="text/javascript">



    $(document).ready(function(){
        $("button").click(function(){

            $.ajax({
                type: 'POST',
                url: 'sendmail.php',
                success: function(data) {
                    alert(data)
                    $("l").text(data);

                }
            });
   });
});
</script>

我知道上面是不正确的 & 它不工作（目前它在弹出窗口中显示 sendmail.php 的文本）我怎样才能让它工作以便我可以执行 sendmail.php ???

更新：

index.html

    <form method="POST" id="myForm" action="sendmail.php">
  <input type="text" name="sender_name" placeholder="Name" required="">
  <input type="text" name="sender_email" placeholder="Email" required="">
  <input type="text" name="subject" placeholder="Subject" required="">
  <textarea placeholder="Message" name="message" required=""></textarea>
  <input type="submit" name="send" value="SEND">
</form>



</div>
<script type="text/javascript">


  $(document).ready(function(){
        $("#myForm").on('submit', function(){
            var formData = $(this).serialize();
            $.ajax({
                type: 'POST',
                url: 'sendmail.php',
                data: formData,
                success: function(response.success) {
                    alert(response.success)
                    $("l").text(response.success);

                }
            });
   });
</script>
    `

【解决方案1】：

使用.on('submit' 和.serialize()，以下内容应该适合您

HTML

<form method="POST" id="myForm" action="sendmail.php">
  <input type="text" name="sender_name" placeholder="Name" required="">
  <input type="text" name="sender_email" placeholder="Email" required="">
  <input type="text" name="subject" placeholder="Subject" required="">
  <textarea placeholder="Message" name="message" required=""></textarea>
  <input type="submit" name="send" value="SEND">
</form>

$(document).ready(function() {
    $("#myForm").on('submit', function(event) {
        event.preventDefault(); 
        var formData = $(this).serialize();
        $.ajax({
            type: 'POST',
            url: 'sendmail.php',
            dataType: "json",
            data: formData,
            success: function(response) { 
                alert(response.success); 
            },
            error: function(xhr, status, error){
                console.log(xhr); 
            }
        });
    });
});

PHP

<?php
if(isset($_POST['message'])){
    $to      = 'queries@mydomain.com';
    $subject = $_POST['subject']; 
    $message = $_POST['message']; 
    $headers = "From: ".$_POST['sender_nam‌e']." <".$_POST['sender_em‌ail‌'].">\r\n"; $headers = "Reply-To: ".$_POST['sender_ema‌il‌']."\r\n"; 
    $headers = "Content-type: text/html; charset=iso-8859-1\r\n";
    'X-Mailer: PHP/' . phpversion();
    if(mail($to, $subject, $message, $headers)) echo json_encode(['success'=>true]); 
    else echo json_encode(['success'=>false]);
    exit;
 }
?>

【讨论】：

我应该这样做吗？请检查更新的问题
@remyboys 是的，这应该适合您使用。您是否遇到问题或遇到错误？
@remyboys 确保添加function(event){event.preventDefault(); 位，如上所示，没有它，它将无法工作。我第一次添加答案时忘记了它，但之后编辑了它
在哪里添加？ function(event){event.preventDefault();@DelightedD0D
@remyboys 添加它，就像上面js 部分中显示的那样，你应该很好

【解决方案2】：

所以像下面的代码一样为你的表单标签提供和 id。

 <form method="POST" action="sendmail.php" id="sendForm">
 <input type="text" name="sender_name" placeholder="Name" required="">
 <input type="text" name="sender_email" placeholder="Email" required="">
 <input type="text" name="subject" placeholder="Subject" required="">
 <textarea placeholder="Message" name="message" required="">  
 </textarea>
 <input type="submit" name="send" value="SEND" id="submitButton">    
 </form>

然后像下面的代码一样更新你的脚本

    $(document).ready(function(){
        $("#submitButton").click(function(event){
         event.preventDefault();
        var datas = $('#sendForm').serialize();

            $.ajax({
                type: 'POST',
                url: 'sendmail.php',
                data: datas,

                success: function(data) {
                    alert(data)
                    $("l").text(data);

                }
            });
   });
});

【讨论】：

不要忘记调用event.preventDefault();，否则html表单将通过正常流程提交，页面将在调用ajax之前刷新;)
当然..谢谢你通知我

【解决方案3】：

您好，给您的表单一个 id 并使用 JS preventDefault()

<form method="POST" id="myForm" action="sendmail.php">
  <input type="text" name="sender_name" placeholder="Name" required="">
  <input type="text" name="sender_email" placeholder="Email" required="">
  <input type="text" name="subject" placeholder="Subject" required="">
  <textarea placeholder="Message" name="message" required=""></textarea>
  <input type="submit" id="sendMail" name="send" value="SEND">
</form>

发送邮件.php

<?php
    if($_POST['send'] == 'SEND'){

    $to      = 'queries@mydomain.com';
    $subject = $_POST['subject']; 
    $message = $_POST['message']; 
    $headers = "From: ".$_POST['sender_nam‌e']." <".$_POST['sender_em‌ail‌'].">\r\n"; $headers = "Reply-To: ".$_POST['sender_ema‌il‌']."\r\n"; 
    $headers = "Content-type: text/html; charset=iso-8859-1\r\n";
    'X-Mailer: PHP/' . phpversion();
    //check if the mail was sent
    if (mail($to, $subject, $message, $headers)) {
        echo json_encode(['result' => true]);
    }else {
        echo json_encode(['result' => false]);
     }
   }
?>

jQuery

$(document).ready(function () {
//send button click
$('#sendMail').on('click', function (e) {
    e.preventDefault();
    $.post('sendmail.php', $('#myForm').serialize(), function (data) {
        //show the results if the mail was sent or not
        var res = $.parseJSON(data);
        if (res.result === true) {
           $('#feedback').html('your mail was sent');
        }else {
           $('#feedback').html('your mail was not sent');
        }
    });
});
});
