如何解决添加更多 65 列时数据表给出错误？
我在我的 mvc asp.net 应用程序中使用数据表，当我处理 65 列时，它工作得很好，但是当我再添加一列时，它给了我错误，即 DataTables 警告：table id=userTrackingList_table -阿贾克斯错误。有关此错误的详细信息，请参阅 http://datatables.net/tn/7. 在控制台上，错误消息是：加载资源失败：服务器响应状态为 400（错误请求）。
我的数据表代码：
`
函数 GetUserTrackingListRecords() {
userTracking = $('#userTrackingList_table').on('error.dt',function (e,settings,techNote,message) {
console.log('An error has been reported by DataTables: ',message);
console.log(e);
console.log(settings);
console.log(techNote);
//HideMainDivOnLoggedOut();
}).DataTable({
"serverSide": true,"processing": true,"bPaginate": true,scrollY: "300px",scrollX: true,scrollCollapse: true,"ajax": {
"url": '/Dashboards/GetUserTrackingData',"dataSrc": function (json) {
userTrackingData = json.data;
return json.data;
},"data": function (d) {
return $.extend({},d,{
//companyCsv: Companies,userId: $("#ddlUser").val(),FromDate: $("#from_date").val(),ToDate: $("#to_date").val()
});
}
},"error": function (e) {
$("body,html").animate({ scrollTop: 0 },'slow');
showMessage(" " + e,"danger","","divMessage",true);
},"dom": "<'row'<'col-sm-6'l><'col-sm-6'B>>" +

},{

//}
}
]
});
}`
if ($.fn.dataTable.isDataTable("#userTrackingList_table")) {
userTracking.draw();
}
else {
GetUserTrackingListRecords();
// setTimeout(ChildTableInquiry(),6000);
}
如您所见，我添加了 65 列，因为我在这里添加了 1 列，它会出错。我已经检查过我的后端完全没问题，只有当列数增加时它才会抛出上述错误。
解决方法
我在我的 ajax 部分犯了错误，通过添加 "type" : "POST" 代码将运行良好。 由于 "type" ajax 请求没有默认定义 "GET" 请求正在工作，并且服务器拒绝了 get 请求。
