HTML表单在不离开当前页面的情况下向PHP表单发送数据 - HTML Form sends data to PHP Form without leaving the current page

我有从我的HTML表单发送数据到我的PHP页面(通过JS/AJAX)，而留在我的当前页面的问题。以下是我目前的位置:

HTML部分:

<!-- Begin the Form --> 
<form id="signup-form" method="POST">
<!-- Input of E-Mail --> 
<div class="seven columns">
           <input type="email" name="email" id="email" placeholder="Your E-Mail">
</div>
<!-- Send Button -->
<div class="five columns">
            <button name="submit" type="button" class="button">Subscribe</button>
</div>
<!-- End of the Form --> 
</form>

PHP:

<?php
require_once 'MCAPI.class.php';
$apikey = 'XXXXXX';
$list_id ='XXXXXX';
$api = new MCAPI($apikey);
$email = $_POST['email'];
echo "Email: ".$email;
$merge_vars = array(' ');
// By default this sends a confirmation email - you will not see new members
// until the link contained in it is clicked!
$retval = $api->listSubscribe( $list_id, $email, $merge_vars );
if ($api->errorCode){
echo "Unable to load listSubscribe()!'n";
echo "'tCode=".$api->errorCode."'n";
echo "'tMsg=".$api->errorMessage."'n";
} else {
echo "E-Mail submitted to the pxCollective Newsletter!";
}
?>

JS:

<script type="text/javascript" >
$(function() {
$(".submit").click(function() {
    var email = $("#email").val();
if(email=='')
{
$('.success').fadeOut(200).hide();
$('.error').fadeOut(200).show();
}
else
{
    $.ajax({
    type: "POST",
    url: "subscribeEmail.php",
    data: email,
    success: function(){
    $('.success').fadeIn(200).show();
    $('.error').fadeOut(200).hide();
    }
    });
}
return false;
});
 });
 </script>

如果我不尝试使用JS/AJAX将其保留在当前页面上，它将直接指向PHP页面，并将用户订阅到邮件列表。你知道我的问题是什么吗?

谢谢!

这一行data: email,应该是data: {email: email},

try this

<script type="text/javascript" >
    $(function() {
        $(".submit").click(function() {
            var email = $("#email").val();
            if(email=='')
            {
                $('.success').fadeOut(200).hide();
                $('.error').fadeOut(200).show();
            }
            else
            {
                $.ajax({
                    type: "POST",
                    url: "subscribeEmail.php",
                    data: {email: email}, // don't data: email,
                    success: function(){
                        $('.success').fadeIn(200).show();
                        $('.error').fadeOut(200).hide();
                    }
                });
            }
            return false;
        });
    });
</script>

您正在使用$('.submit').click()，但没有submit类的元素!你的提交按钮是button类。

您应该使用$('#signup-form').submit()，并将<button>更改为<input type="submit">。

Try

$.ajax({
type: "POST",
url: "subscribeEmail.php",
data: {email:email},
success: function(){
$('.success').fadeIn(200).show();
$('.error').fadeOut(200).hide();
}
});

应该是"email="+email
