【问题描述】:
我已经工作了一个星期,试图帮助一个朋友处理他的 JQuery 数据表。该表显示了志愿者申请者和通过活动进行的工作。前端页面包含 JS Datatable 脚本,ColdFusion 页面用于查询 MySQL 数据库。当页面最初加载时,调试控制台中显示以下错误。
Uncaught TypeError: Cannot read property 'DT_RowId' of undefined
at Object.rowIdFn (jquery.dataTables.min.js:19)
at N (jquery.dataTables.min.js:16)
at HTMLTableElement.<anonymous> (jquery.dataTables.min.js:92)
at Function.each (jquery.js:374)
at n.fn.init.each (jquery.js:139)
at n.fn.init.m [as dataTable] (jquery.dataTables.min.js:82)
at HTMLDocument.<anonymous> (index.cfm:897)
at j (jquery.js:3099)
at Object.fireWith [as resolveWith] (jquery.js:3211)
at Function.ready (jquery.js:3417)
然后当JS脚本刷新并重新检查数据库时,我得到以下错误。
Uncaught TypeError: Cannot read property '0' of undefined
at jquery.dataTables.min.js:19
at Object.b.fnGetData (jquery.dataTables.min.js:12)
at B (jquery.dataTables.min.js:17)
at Ga (jquery.dataTables.min.js:14)
at mb (jquery.dataTables.min.js:66)
at T (jquery.dataTables.min.js:31)
at Ub (jquery.dataTables.min.js:107)
at r.<anonymous> (jquery.dataTables.min.js:108)
at r.iterator (jquery.dataTables.min.js:99)
at r.<anonymous> (jquery.dataTables.min.js:108)
这是 JS 文件的样子。我正在尝试使用 JQuery Datatable 1.10 版。

}
});
});
setInterval(function() {
$('#displayData').DataTable().ajax.reload();
}, 30000);
在coldfusion页面,系统检查了两个表,应该返回信息,但一直报错。包括下面是我的 CF 页面。

我知道我遗漏了一些东西,或者我的 JSON 调用不正确,我已经阅读了 Stack Overflow 和 JQuery DataTable 站点,但没有真正谈论 JSON 内容的格式。有人遇到过这个问题吗?
