我有这个 php，它可以将一些图像从数据库加载到前端。我现在想做的是，当我将鼠标悬停在(鼠标悬停)图像上时，我想使用 AJAX 将 $item->job_id 传递给另一个 php 脚本，以便我可以使用该 job_id 从另一个图像中查找该图像的名称数据库中的表。

其他 php 脚本可能看起来像这样

    <?php require_once("../includes/site_init.php");
require_once("../includes/site_init.php");

if(isset($_POST['jobId']) && $_POST['jobId'] !==NULL && $_POST['jobId'] !==0){
  $job_id = $_POST['jobId'];

  $portfolio_item_name = Job::find_by_sql('SELECT name FROM '.'job'." WHERE id = '" . $job_id . "' LIMIT 1");
  echo $portfolio_item_name[0]->name;
}else {
  echo 'result failed';
}
?>

因此 job_id 将来自调用此 php 文件的 AJAX 请求，而 AJAX 本身将从上面的前一个 php 获取 job_id。对于这样的事情，AJAX 会是什么样子？ PHP 脚本需要进行哪些更改？

最佳答案

您可以使用 jQuery和 AJAX异步发送 $item->job_id到 PHP 页面。解决方案是，

  • 将下面的 jQuery 代码放在结尾 </body> 的正上方标签，像这样:

    <!--YOUR CODE-->                

    <script src="http://code.jquery.com/jquery-1.11.0.min.js"></script> 
    <script>
        $(document).ready(function(){
            $(document).on('mouseover', '.grid-img-hover', function(){
                // job id
                var jobId = $(this).parent().find('.title-wrap').text();

                // AJAX request
                $.ajax({
                    url: 'yourpage.php',
                    type: 'POST',
                    data: {jobId: jobId},
                    success: function(data) {
                        // success
                        alert(data);
                    },
                    error: function(jqXHR, textStatus, errorThrown){
                        // error
                        alert(errorThrown);
                    }
                });
            });
        });
    </script>
    </body>
    </html>

    注意:不要忘记更改 url 中的 yourpage.php AJAX 请求的设置。

  • 在 yourpage.php 页面上，按以下方式处理您的 AJAX 请求，

    require_once("../includes/site_init.php");

    if(isset($_POST['jobId'])){
        $job_id = $_POST['jobId'];

        $portfolio_item_name = Job::find_by_sql('SELECT name FROM '.static::$table_name." WHERE id = '" . $job_id . "' LIMIT 1");
        echo $portfolio_item_name->name;
    }
