I am using Datatable pipeline for generating table. My table has dynamic column means it has no fixed column. The column column number changes with the change of a month. Suppose, during current month the table has 4 column but for november it has 32 columns. When I changes month to november,it gives me Cannot read property 'style' of undefined
this error.
My datatable initilization function:
function monthlyAttendanceStatusDatatableInit(tableIdOrCss, url, columns, sortArr, pageLength, year, month) {
console.log(columns);
var param = {
"responsive": false,
// "columnDefs": [
// {responsivePriority: 1, targets: -1},
// {responsivePriority: 2, targets: 0}
// ],
"aLengthMenu": [[10, 20, 50, -1], [10, 20, 50, 'All']],
"pageLength": pageLength || 10,
"iDisplayLength": pageLength || 10,
//"language": { search: "" },
"sPaginationType": "simple_numbers", // you can also give here 'simple','simple_numbers','full','full_numbers'
"oLanguage": {
"sSearch": "Search:",
"sProcessing": "Loading..."
},
"ajax": $.fn.dataTable.pipeline( {
url: url,
data: {
'month': month,
'year': year
},
pages: 2 // number of pages to cache
}),
"processing": true,
"serverSide": true,
"searching": true,
// "bPaginate": true,
// "fnDrawCallback":function(){
// if(typeof callBack == 'function'){
// callBack();
// }
// },
"destroy": true,
"paging": true,
"retrieve": false,
"aoColumns": columns,
"aaSorting": sortArr, //[[ 0, "asc" ],[ 1, "desc" ]] // Sort by first column descending
// "scrollX": true,
// "createdRow": function( row, data, dataIndex ) {
// $(row).attr('id', 'employee-'+data.id);
// }
};
// $(tableIdOrCss).remove();
var table = $(tableIdOrCss).DataTable(param);
return table;
}
I genrating column using server side data. Columndefinition function:
function getColumnDefinition(year, month) {
var columns = [
{"sTitle": "ID", "mData": "e_id", "bSortable": true},
{"sTitle": "Employee Name", "mData": "employee_name", "bSortable": true},
];
var totalDay = getDayCount(year, month);
var monthS = month.slice(0, 3);
for (var i = 1; i <= totalDay; i++) {
if (i < 10) {
var date = '0' + i.toString();
}else {
var date = i.toString();
}
var dateColumn = {"sTitle": date + "-" + monthS, "mData": date, "bSortable": true};
columns.push(dateColumn);
}
return columns;
}
I am unable to find any solution
from Uncaught TypeError: Cannot read property 'style' of undefined using datatable pipeline
