完全动态的数据表 PHP

Question

我正在尝试在模式中创建一个完全动态的数据表打开。起初它给了我正确的结果，但是当我打开一个新的模式时，它给了我这个错误：

DataTables 警告：table id=tableDetails - 无法重新初始化 DataTable。有关此错误的更多信息，请参阅http://datatables.net/tn/3

希望您能提供帮助。谢谢。

这是我正在使用的代码： [模态]：

<div id="myModal" class="modal fade bs-example-modal-lg" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog modal-lg" role="document">
    <div class="modal-content">
        <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
            <h4 class="modal-title" id="modalTitle"></h4>
        </div>

        <div class="modal-body">
            <table class="table table-hover table-bordered" id="tableDetails"></table>
        </div>
    </div>
</div>

Answer 1

在主页中只包含一次 datatable js。 删除主页中所有初始化数据表的js代码。 在脚本标签的页脚之后添加js代码以在模态中初始化。

如果这不起作用，请尝试在模式开始关闭时在 js 上添加数据表销毁。

我希望我是清楚的。

Answer 2

这是一个非常常见的问题，您可以避免 (...) 深入阅读数据表文档。我曾经为你的同样问题浪费了好几个小时。

最后你解决了它在创建我的表之前销毁任何数据表初始化，在你的情况下你想添加一个：

 if ( $.fn.DataTable.isDataTable('#myAwesomeTable') ) {
  $('#myAwesomeTable').DataTable().destroy();
}

初始化前的右图

 if ( $.fn.DataTable.isDataTable('#myAwesomeTable') ) {
      $('#myAwesomeTable').DataTable().destroy();
    }




        $('#myAwesomeTable').DataTable({
            "responsive": true,
            "processing" : true,
            "ajax" : {
                "url" : "...",
                dataSrc : ''
            },
            "columns" : [
            {
                "data" : "id"
            }, {
                "data" : "name"
            }]
        }).draw(true).columns.adjust();
      },
      error: function(XMLHttpRequest, textStatus, errorThrown) {
              console.log("Status: " + textStatus); alert("Error: " + errorThrown);
      }
    });
});

在 URL 中，您可以使用一个 php 文件，该文件将具有一个简单的 PDO PHP MYSQL 调用，并且您可以像这样回显一个 json_encode 函数：

<?php

require "../../../class/PDO.class.php";
require "../../../class/helper.class.php";

$new = $_POST['id'];
$mundialorder = $_POST['irOrder'];

//var_dump($_POST);

 $valores = array(
      $new,
      $mundialorder
      );

 $DB = new Db(DBHost, DBName, DBUser, DBPassword);

    $sql = "UPDATE me SET please= ? WHERE person = ?";


    if($DB->query($sql,$valores) > 0)  {

            //$usuario = Helper::obtain_my_simple_JSON();

             $msg = "S";





        $data['success'] = true;
        $data['message'] = "good";

    }else{
        $data['success'] = false;
        $data['errors'] = "Error";
    }



echo json_encode($data);

?>
