为第 0 行请求了未知参数 'ASSET_NAME'

Question

我正在尝试从 AJAX 创建数据表，但仍然出现错误

Requested unknown parameter 'ASSET_NAME' for row 0.

即使 JSON 格式正确（由 http://www.jslint.com/ 验证）并且列列表与 JSON 来源中引用的列相同：

 $(document).ready(function() {
     $('#auditResults').dataTable( {
         "aaData": '[{"ASSET_NAME":"CVCMAgent","a1_hostname":"czcholsint1027.prg-dc.dhl.com","a1_port":"5000","a1_asset_version":"1.6","a1_build":"1504130525"},
          {"ASSET_NAME":"CVCMAgent","a1_hostname":"czcholsint1027.prg-dc.dhl.com","a1_port":"6000","a1_asset_version":"1.6","a1_build":"1504130525"}]',
          "aoColumns": [
            {"sTitle": "ASSET_NAME", "mData": "ASSET_NAME"} ,  {"sTitle": "a1_hostname", "mData": "a1_hostname"} ,  {"sTitle": "a1_port", "mData": "a1_port"} ,  {"sTitle": "a1_asset_version", "mData": "a1_asset_version"} ,  {"sTitle": "a1_build", "mData": "a1_build"}  
             ]
     } );
 } );

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
<table id="auditResults" name="auditResults" class="display" cellspacing="0" width="100%">
  <thead>
    <tr>
     
       <th>ASSET_NAME</th>
     
       <th>a1_hostname</th>
     
       <th>a1_port</th>
     
       <th>a1_asset_version</th>
     
       <th>a1_build</th>
         </tr>
  </thead>
</table>

我尝试了很多组合，但都没有成功。

那里出了什么问题？

谢谢雷迪

您将 JSON 作为字符串传递，您应该将其作为 JSON 传递：

"aaData": [{"ASSET_NAME":"CVCMAgent","a1_hostname":"czcholsint1027.prg-dc.dhl.com","a1_port":"5000","a1_asset_version":"1.6","a1_build":"1504130525"},{"ASSET_NAME":"CVCMAgent","a1_hostname":"czcholsint1027.prg-dc.dhl.com","a1_port":"6000","a1_asset_version":"1.6","a1_build":"1504130525"}]',

如果您出于某种原因无法做到这一点，您可以使用 JSON.parse() :

"aaData": JSON.parse('[{"ASSET_NAME":"CVCMAgent","a1_hostname":"czcholsint1027.prgdc.dhl.com","a1_port":"5000","a1_asset_version":"1.6","a1_build":"1504130525"},          {"ASSET_NAME":"CVCMAgent","a1_hostname":"czcholsint1027.prgdc.dhl.com","a1_port":"6000","a1_asset_version":"1.6","a1_build":"1504130525"}]'),
