大家好，我正在尝试使用数据表来反映我的数据库，但我没有在数据表中得到结果。需要帮助！！！

我的控制器：-

public function __construct() {
    parent::__construct();
    $this->load->library('Datatables');
    $this->load->library('table');
    $this->load->database();
}
function index()
{

    //set table id in table open tag
    $tmpl = array ( 'table_open'  => '<table id="big_table" border="1" cellpadding="2" cellspacing="1" class="mytable">' );
    $this->table->set_template($tmpl); 

    $this->table->set_heading('Student ID','Name','Student Code','Class');

    $this->load->view('subscriber_view');
}
//function to handle callbacks
function datatable()
{
    $this->datatables->SELECT ('*', 'class')
                     ->unset_column('student_id')
                     -> FROM ('students as s1')
                     ->join ('student_class as s2','s1.class_id = s2.class_id'); 

    echo $this->datatables->generate();
}

}

         },
                'fnServerData': function(sSource, aoData, fnCallback)
            {
              $.ajax
              ({
                'dataType': 'json',
                'type'    : 'POST',

                'success' : fnCallback
              });
            }
    } );
} );
</script>
<h1>Student Management</h1>
<?php echo $this->table->generate(); ?>
    </div>
</body>
</html>

我的输出：-

{"sEcho":0,"iTotalRecords":2,"iTotalDisplayRecords":2,"aaData":[["1","Ahmad","Niza","451","AA1","A1"],["2","Ahmadi","Reza","452","AA2","A2"]],"sColumns":"*"}

这段代码有什么问题？

提前感谢您的帮助。

【问题讨论】：

你想要的输出是什么？
它应该在数据表中显示结果......但它只给出该输出......独立检查数据表并且它运行良好。

标签： javascript php json codeigniter datatable

【解决方案1】：

尝试添加这一行：

"sDom": "frti"

所以你的代码看起来像：

var oTable = $('#big_table').dataTable( {
    "bProcessing": true,
    "bServerSide": true,
    "sDom": "frti" //added this line
    "sAjaxSource": '<?php echo site_url('datatable'); ?>',
            "bJQueryUI": true,
//rest of your code

根据数据表documentation：

sDom：

此初始化变量允许您准确指定希望 DataTables 在 DOM 中的哪个位置注入它添加到页面的各种控件（例如，您可能希望在表格顶部的分页控件）。也可以添加 DIV 元素（带有或不带有自定义类）来辅助样式。使用以下语法：

允许以下选项：
    'l' - Length changing
    'f' - Filtering input
    't' - The table!
    'i' - Information
    'p' - Pagination
    'r' - pRocessing
The following constants are allowed:
    'H' - jQueryUI theme "header" classes ('fg-toolbar ui-widget-header ui-corner-tl ui-corner-tr ui-helper-clearfix')
    'F' - jQueryUI theme "footer" classes ('fg-toolbar ui-widget-header ui-corner-bl ui-corner-br ui-helper-clearfix')
The following syntax is expected:
    '<' and '>' - div elements
    '<"class" and '>' - div with a class
    '<"#id" and '>' - div with an ID
Examples:
    '<"wrapper"flipt>'
    'ip>'

最重要的是t，因为那是桌子...

我希望这会有所帮助。
