Javascript JSON格式的Ajax源数据-无法获取属性'；长度'；指未定义的或空的引用

我试图将json数据（从Web API ajax调用中检索）加载到jQuery DataTables，但出现以下错误：

中第38行第314列的未处理异常

0x800a138f-JavaScript运行时错误：无法获取属性“length” 指未定义的或空的引用

这是我的jQuery调用：

$(document).ready(function () {
    $('#stat').DataTable({
        "responsive": true,
        "paging": false,
        "ordering": false,
        "info": false,
        "bFilter": false,
        "processing": true,
        "serverSide": true,
        "ajax": {
            'url': 'http://localhost:61178/api/financeStats'
        }
    });
});

这是从Web API调用检索到的JSON数据：

原因 错误

无法获取未定义或空引用的属性“length”（IE）或
无法使用jQuery DataTables读取未定义的属性“length”（其他浏览器），通常意味着插件无法响应Ajax请求访问数据

您的代码有几个问题


您已使用
serverSide:true
启用了服务器端处理模式，但数据的格式改为客户端处理模式。删除
serverSide:true
以使用客户端处理模式
您的数据是对象数组。在这种情况下，您需要使用option在数据集中使用option为每个列定义属性名称
您需要使用
dataSrc:“
来匹配JSON数据格式，有关更多信息，请参阅

解决方案
使用以下代码：

$（'#stat'）。数据表({
“响应”：正确，
“分页”：false，
“命令”：错误，
“信息”：错误，
“搜索”：错误，
“ajax”：{
“url”：”http://localhost:61178/api/financeStats",
“dataSrc”：”
},
“栏目”：[
{“数据”：“描述”}，
{“数据”：“TotAgents”}，
{“数据”：“总额”}
]
});

Get“对象不支持属性或方法'DataTable'”error@Vkl125，很可能您忘记了包含DataTable v1.10 JS文件，或者使用旧的DataTable Library v.1.9。
