javascript - AJAX 联系表单重新加载页面但不发送电子邮件

Question

嗨，就像标题所说，我的代码似乎在点击发送按钮时重新加载页面，但从未真正发送电子邮件。我已经尝试并阅读了我能阅读的所有内容，但没有任何内容可以让它正常工作。我衷心感谢您的帮助。

<div class="row half">

</div>

<div class="row">
    <div class="12u">
        <ul class="actions">
            <li><input type="submit" class="button" value="Send Message" /></li>

        </ul>
    </div>

</div>

</form>

PHP:

<?php
    // Email Submit
    // Note: filter_var() requires PHP >= 5.2.0
    if ( isset($_POST['email']) && isset($_POST['name']) && isset($_POST['message']) &&      filter_var($_POST['email'], FILTER_VALIDATE_EMAIL) ) {
        // detect & prevent header injections
        $test = "/(content-type|bcc:|cc:|to:)/i";
        foreach ( $_POST as $key => $val ) {
            if (preg_match( $test, $val ))
            exit;
        }

        //send email
        mail( "test@gmail.com", "Contact Form: ".$_POST['name'], $_POST['text'], "From:" .      $_POST['email'] );
    }
?>

JS:

$('#contact').submit(function(e) {
e.preventDefault();
var name = $("#name").val();
var email = $("#email").val();
var message = $("#message").val();
//var dataString = 'name=' + name + '&email=' + email + '&message=' + message;

$.ajax({
    type : "POST",
    url : "mail.php",
    data : {name:name,email:email,message:message},
    cache : false,
    success : function() {              
        $("#contact").fadeOut(300);
        $("#notice").fadeIn(400);
    }
});
return false;

});

感谢您的宝贵时间。

假设您的电子邮件功能在AJAX部分运行良好，您需要使用event.preventDefault()

还注意到 mail.php 中有这个

if ( isset($_POST['email']) 
&& isset($_POST['name']) && 
**isset($_POST['text'])** && 
filter_var($_POST['email'], FILTER_VALIDATE_EMAIL) ) {
}

这将失败 isset($_POST['text']) 因为没有 post 元素，我想它应该是 isset($_POST['message']) >

此外，您的表单元素缺少 id，请将其添加为

<!-- Contact Form-->
<div class="content style4 featured">
<div class="container small">
    <form id="contact" form method="post">

    <div class="row half">
        <div class="6u"><input type="text" class="text" name="name" id ="name" placeholder="Name" /></div>
        <div class="6u"><input type="text" class="text" placeholder="Email" name="email" id="email"/></div>
    </div>

    <div class="row half">
        <div class="12u"><textarea name="text" placeholder="Message" id="message"></textarea></div>
    </div>

    <div class="row">
        <div class="12u">
            <ul class="actions">
                <li><input type="submit" class="button" value="Send Message" /></li>
                <li><input type="reset" class="button alt" value="Clear Form" /></li>
<p class="success" style="display:none">Your message has been sent successfully.</p>
                <p class="error" style="display:none">E-mail must be valid and message must be longer than 100 characters.</p>
            </ul>
        </div>

    </div>

    </form>
</div>
</div>


<script>
    $('#contact').submit(function(e) {
        e.preventDefault();
        var name = $("#name").val();
        var email = $("#email").val();
        var message = $("#message").val();
        //var dataString = 'name=' + name + '&email=' + email + '&message=' + message;

        $.ajax({
            type : "POST",
            url : "mail.php",
            data : {name:name,email:email,message:message},
            cache : false,
            success : function() {              
                $("#contact").fadeOut(300);
                $("#notice").fadeIn(400);
            }
        });
        return false;
    });

    </script>

我刚刚测试过，它对我有用。
