Question

我想在表中填充数据表值和数据库值。下面是我的代码清单，一切似乎都没问题但是返回了错误＆＃34; TypeError：aData未定义＆＃34;所以没有创建数据表

<script type="text/javascript">
$(document).ready(function() {
    $('#listax').dataTable({
        "bProcessing": true,
        "bLengthChange": true,
        "bFilter": true,
        "bSort": true,
        "bInfo": true,
        "bAutoWidth": true,
        "bServerSide": true,
        "sServerMethod": "POST",
        "sAjaxSource": "<?php echo base_url(); ?>ajax_live/getUsers",
        "aoColumns": [
            null,
            null //put as many null values as your columns
        ]
    });
});
</script>

<table id="listax"></table>

服务器端

 function getUsers(){
     $this->db->select('id,username');
     $query = $this->db->get('user');
     $data = $query->result();
     echo json_encode($data); 
 }

这是json encode返回的数据

[
    {"id":"6","username":"Lab23"},
    {"id":"11","username":"MaryMM"}
]

Answer 1

当我这样做时，我不得不定义列发送示例数组;

Array
(
    [0] => stdClass Object
        (
            [id] => 6
            [username] => "Lab23"
        )
    [1] => stdClass Object
        (
            [id] => 11
            [username] => "MaryMM"
        )
)

因此，如果您的json编码数组的键值为 id 且用户名，则数据表中将包含以下段。

$(document).ready(function() {
    $('#listax').dataTable({
        "bProcessing": true,
        "bLengthChange": true,
        "bFilter": true,
        "bSort": true,
        "bInfo": true,
        "bAutoWidth": true,
        "bServerSide": true,
        "sServerMethod": "POST",
        "sAjaxSource": "<?php echo base_url(); ?>ajax_live/getUsers",
        "aoColumns":[
            {"mDataProp":"id"},
            {"mDataProp":"username"}
        ]
    });
});

数据表TypeError：aData未定义
