jquery 没有发送 post 数据

Question

我在使用 jQuery 从一页到另一页 post 处理数据时遇到问题。 post 根本没有提交。我使用网络选项卡检查了 post 数据，我可以看到没有发送任何表单数据。但我不知道为什么。我按照建议 here 尝试了 evt.preventDefault();。但是结果是一样的

那么这是如何工作的。 index.php posts 数据到 referrer-reason.php 更改 div 并运行新查询并在 div 中显示新数据。 #backref 是一个后退按钮，它从 index.php 但在 referrer-company.php 中加载相同的代码。目前 referrer-reason.php 没有 post 向 referrer-company.php 发送数据。但是当 post 将数据从 index.php 发送到 referrer-reason.php.

时，相同的代码可以工作

它返回 200 OK 但 post 数据中没有实际内容，如下所示。

我对 jQuery 还很陌生，所以这是我在努力学习的同时尽量保持简单。

关于我还可以尝试什么的任何建议？

index.php 上的代码：

$(document).ready(function () {
$('.clickthrough2').click(function () {
    companyId = $(this).attr('id'); 

    $.post('./ajax/referrer-reason.php', {
        clickthrough: $('#company-'+companyId+' .clickthrough').val(),
        ref_date_from2: $('#company-'+companyId+' .ref_date_from2').val(),
        ref_date_to2: $('#company-'+companyId+' .ref_date_to2').val()
    },
    function (data) {
        $('#declined2').html(data);
    });
});     
});

POST 数据从 index.php 到 referrer-reason.php.

引荐原因代码

$(document).ready(function () {
$('#backref').click(function () {
    companyId = $(this).attr('id'); 
    $.post('./ajax/referrer-company.php', {
        clickthrough: $('#company-'+companyId+' .clickthrough').val(),
        ref_date_from2: $('#company-'+companyId+' .ref_date_from2').val(),
        ref_date_to2: $('#company-'+companyId+' .ref_date_to2').val()
    },
    function (data) {
        $('#declined2').html(data);
    });
});     
});

编辑： 要求的额外细节：

收集 POST:

$selected = $_POST['clickthrough'];
$date_from = $_POST['ref_date_from2'];
$date_to = $_POST['ref_date_to2'];

我得到：

PHP Notice:  Undefined index: clickthrough in /var/www/clients/client1/web51/web/sections/dash/ajax/referrer-company.php on line 35, referer: http://www.domain.com/sections/dash/index.php
PHP Notice:  Undefined index: ref_date_from2 in /var/www/clients/client1/web51/web/sections/dash/ajax/referrer-company.php on line 36, referer: http://www.domain.com/sections/dash/index.php
PHP Notice:  Undefined index: ref_date_to2 in /var/www/clients/client1/web51/web/sections/dash/ajax/referrer-company.php on line 37, referer: http://www.domain.com/sections/dash/index.php

另外第二个post数据有：

Content-Length:0

被替换的来自 referrer-reason.php 的代码：

            <div id="declined2" class="declined4">
                <h4>Declined Quote <br />Reasons</h4>
                <div class="statgrid">
<?php
    $result = $mysqli->query($quotes_q);    
    while ($row = $result->fetch_array()) {
?>
                <div id="company-<?php echo $row['company_id'];?>">
                    <input type="hidden" class="ref_date_from2" value="<?php echo $date_from; ?>" />
                    <input type="hidden" class="ref_date_to2" value="<?php echo $date_to; ?>" />
                    <input type="hidden" class="clickthrough" value="<?php echo $row['company_id'] ?>" />
                        <a><div id="<?php echo $row['company_id'];?>" class="clickthrough2 col-5-6"><?php echo $row['decline_reason']; ?></div></a>
                    <div class="col-1-6"><?php echo $row['company_id_count']; ?></div>  
                </div>
<?php
    }

Answer 1

我错误地映射了我的 div，这就是没有返回日志的原因。

jquery 没有发送 post 数据

jquery no sending post data

jquery
