jquery不发送post数据

Question

我在使用jQuery将数据从1页上传到另一页时遇到了困难。这篇文章根本没有提交。我已经使用Network来检查post数据，并且我可以看到没有发送任何表单数据。但我不知道为什么。我尝试了evt.preventDefault();，如建议的here。但结果是一样的。

这是怎么回事。index.php将数据发布到referrer-Rational.php，后者更改div并运行新的查询，并在div中显示新数据。#backref是一个back按钮，它从index.php加载相同的代码，但在referrer-company.php中。目前，referrer Rational.php并没有将数据发布到referrer company.php。但是同样的代码在将数据从index.php发布到Referator-Rational.php时也是有效的。

它将返回200 OK，但在post数据中没有实际内容，如下所示。

我对jQuery相当陌生，所以这是我试图保持它简单，而我学习它错综复杂。

还有什么我可以尝试的建议吗？

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);
    });
});     
});

将数据从index.php发布到Referator-Rational.php。

推荐人守则-理由

$(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);
    });
});     
});

将数据从referrer-Receign.php发布到referrer company.php。

编辑:请求额外详细信息：

收集邮件后：

$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

此外，第二次发布的数据有：

Content-Length:0

要替换的referrer Rational.php中的代码：

            <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

我不正确地映射我的div，这就是为什么没有日志返回。
