I am trying to add page number in datatble pdf export, I got code from its official site after adding this code pdf button got disappearing and getting 'Uncaught ReferenceError: doc is not defined
at HTMLDocument' error in console.
$('#table2').DataTable({
dom: 'Bfrtip',
buttons: [
{
extend: 'pdfHtml5',
title: 'Data export',
filename: 'dt_custom_pdf',
pageSize: 'A4',
exportOptions: {
columns: ':visible',
search: 'applied',
order: 'applied'
},
},
doc['footer']=(function(page, pages) {
return {
columns: [
'Left part of footer',
{
alignment: 'right',
text: [
{ text: page.toString(), italics: true },
' of ',
{ text: pages.toString(), italics: true }
]
}
],
margin: [10, 0]
}
});
]
});
You did not define customize function to dataTable that why getting doc error you need to change
$('#table2').DataTable({
dom: 'Bfrtip',
buttons: [
{
extend: 'pdfHtml5',
text: 'Pdf',
filename: 'dt_custom_pdf',
pageSize: 'A4',
exportOptions: {
columns: ':visible',
search: 'applied',
order: 'applied'
},
customize: function ( doc ) {
doc['footer']=(function(page, pages) {
return {
columns: [
{
alignment: 'center',
text: [
{ text: page.toString(), italics: true },
' of ',
{ text: pages.toString(), italics: true }
]
}
],
margin: [10, 0]
}
});
}
}
]
});
I am using datatable but by default it shows top 10 rows, to see other rows you have to click on buttons at bottom to show other rows. I tried pagelength(), page.len(), "lengthChange": false etc but nothing work for me.
<script>
$(document).ready(function() {
var handleDataTableButtons = function() {
if ($("#datatable-buttons").length) {
$("#datatable-buttons").DataTable({
dom: "Bfrtip",
buttons: [
{
extend: "copy",
className: "btn-sm"
},
{
extend: "csv",
className: "btn-sm"
},
{
extend: "excel",
className: "btn-sm"
},
{
extend: "pdfHtml5",
className: "btn-sm"
},
{
extend: "print",
className: "btn-sm"
},
],
responsive: true
});
}
};
TableManageButtons = function() {
"use strict";
return {
init: function() {
handleDataTableButtons();
}
};
}();
$('#datatable').dataTable();
$('#datatable-keytable').DataTable({
keys: true
});
$('#datatable-responsive').DataTable();
$('#datatable-scroller').DataTable({
ajax: "js/datatables/json/scroller-demo.json",
deferRender: true,
scrollY: 380,
scrollCollapse: true,
scroller: true
});
$('#datatable-fixed-header').DataTable({
fixedHeader: true
});
var $datatable = $('#datatable-checkbox');
$datatable.dataTable({
'order': [[ 1, 'asc' ]],
'columnDefs': [
{ orderable: false, targets: [0] }
]
});
$datatable.DataTable( {
order: [[2, 'asc']],
rowGroup: {
dataSrc: 2
}
} );
$datatable.on('draw.dt', function() {
$('input').iCheck({
checkboxClass: 'icheckbox_flat-green'
});
});
TableManageButtons.init();
});
</script>
Other features of datatable working perfectly only SHOW 10,20,50,100 option does not appear on the top of the table. so user can select number of rows he want to see on same page.
I am using a databales javascript in my web site, with html5 buttons
https://datatables.net/extensions/buttons/examples/html5/simple.html , is working fine, but now I want to allow resize on fly the columns of the datatables , so I found this http://legacy.datatables.net/extras/thirdparty/ColReorderWithResize/
But the problem now is, I don´t know how to use both together.
myApp.table = $('#TableId').DataTable(
{
rowReorder: { update: false },
columnDefs: [
{ "width": "5%", "targets": [0] },
{ "className": "text-left custom-middle-align", "targets": [0, 1, 2] },
{ orderable: true, className: 'reorder', targets: 0 },
{ orderable: false, targets: '_all' }
],
autoWidth: false,
sDom: "Rlfrtip", //--> here is the code to resize columns
dom: '<"html5buttons"B>lTfgitp', // here the code to see the buttons
buttons: [
{ extend: 'copy' },
{ extend: 'csv' },
{ extend: 'excel', title: 'ExampleFile' },
{ extend: 'pdf', title: 'ExampleFile' },
{
extend: 'print',
customize: function (win) {
$(win.document.body).addClass('white-bg');
$(win.document.body).css('font-size', '10px');
$(win.document.body).find('table')
.addClass('compact')
.css('font-size', 'inherit');
}
}
],
In fact I don´t understand well the code used by datatables Rlfrtip and B>ltfgitp
Thanks in advance.

I am trying to get rows from back-end response on each scroll. I get
an AJAX response, but I can't get full row, it eats up the data
most probably the last one.
I tried with so other alternative, but it's not working at all, I tried redraw and reload in AJAX.
Here goes my js code:
var table= $('#subscriber_list').DataTable({
responsive: true,
"processing":true,
serverSide: true,
"scrollCollapse":true,
"sDom":"BifrtS",
scrollY:'35vh',
scrollCollapse: true,
paging:false,
"oScroller": {
"displayBuffer": 2,"loadingIndicator": true
},
"ajax": {"url": $('#data_table_column_list').attr("url"),"type": 'POST',"data":{'type':subscriber_type,'end_date_from':end_date_from,'end_date_to':end_date_to}},
"columns": JSON.parse($('#data_table_column_list').val().replace(/\'/g, '"')),
"columnDefs": [
{ "orderable": false, "targets": 2 }
],
buttons: [
{
extend: 'excelHtml5',
text: 'Export selected',
exportOptions: {
columns: ':visible:not(.not-exported)',
modifier: {
selected: true
}
},
title: 'Data export'
},
{
extend: 'excelHtml5',
text: 'Export All',
exportOptions: {
columns: ':visible:not(.not-exported)'
},
title: 'Data export'
}
]
});
You need one or both of the following depending on how you want the table to work.
Right now, it's getting cut off because the default in Datatables is 10 rows. You have paging set to false, so any results after the 10th are now shown.
Either switch this: paging:false,
to: paging:true,
That'll give you multiple pages of results with 10 on each page.
You can also add "pageLength": 50 or some other value if you want more than 10 rows per page.
here i am using same data table from multiple radio button switch, on switching i get warning from data table can't be re-initialised , since i know when i use table.destroy(); it destroy's all the object's created at while i switch the options, but have alternate to use it , what to do now ???? , running out of idea
i was referring this actually
https://datatables.net/manual/tech-notes/3
$('.subscriber_type').on('change',function (e){
var table = $('#subscriber_list').DataTable();
subscriber_data_table($(this).val(),$('#datepicker_from').val(),$('#datepicker_to').val());
});
subscriber_data_table("all",null,null);
function subscriber_data_table(subscriber_type,end_date_from,end_date_to) {
$('#subscriber_list').DataTable({
responsive: true,
"processing": true,
serverSide: true,
paging:true,
"pageLength":50,
"drawCallback": function( settings ) {
console.log( 'hit began' );
},
"sScrollY": "379",
"sDom":"BifrtS",
"oScroller": {
"displayBuffer": 2,"loadingIndicator": true
},

I am using Datatables (datatables.net) successfully to display all the data I need. But I am having difficulty understanding how to pull out selected column data from a json object. I have failed to JSON.stringify the object, as well as attempt to access the properties of the object directly.
The use of the datatables allows the user to select multiple rows and a built in button will perform a submit action to my rails server. I currently cannot access the object to parse the data. I may need a loop and thats fine, but again, I am having difficulty understanding the library on multiple select.
I have successfully console.log the object and verified the data I want is present. I currently want the 1 index of Array[12] for n selected rows. I have figured out how to provide a count of the selected rows, so I can parse the object using the count as a loop limiter. But again my attempts have failed.
Console.log object:
[Array[12], Array[12], Array[12], context: Array[1], selector: Object, ajax: Object, colReorder: Object, keys: Object]
0:Array[12]0:""1:"36"2:
Code:
$(document).ready(function() {
$('.stay').DataTable( {
dom: "<'row'<'col-sm-8'B><'col-sm-4'f>>"+ 'rt' + "<'row'<'col-sm-6'i><'col-sm-6'p>>",
buttons: [
'selectNone',
'selectAll',
{
extend: 'selected',
text: 'Assign Rooms',
action: function ( e, dt, node, config ) {
var rows = dt.rows( { selected: true } ).count();
var selected_rows = dt.rows( {selected: true} ).data(0);
console.log(selected_rows);
url = window.location;
// index = url.indexOf("housekeeper")
// alert(index);
alert( 'There are '+rows+'(s) selected in the table' );
alert(selected_rows[0])
// $.ajax({
// url: "/BookCreate/?mdate="+mdate+"&phone="+phone,
// type: "post",
// data: values,
// success: function(){
// alert('Saved Successfully');
// },
// error:function(){
// alert('Error');
// }
// });
}
},
{
extend: 'colvis',
text: 'Columns',
autoClose: true,
},
{
extend: 'copy',
text: '<i class="fa fa-files-o"></i>',
exportOptions: {
columns: ':visible'
}
},
{
extend: 'excel',
text: '<i class="fa fa-file-excel-o"></i>',
exportOptions: {
columns: ':visible'
}
},
{
extend: 'csv',
text: '<i class="fa fa-file-code-o"></i>',
exportOptions: {
columns: ':visible'
}
},
{
extend: 'pdf',
text: '<i class="fa fa-file-pdf-o"></i>',
exportOptions: {
columns: ':visible'
}
},
{
extend: 'print',
text: '<i class="fa fa-print"></i>',
exportOptions: {
columns: ':visible'
}
},
],
columnDefs: [ {
visible: false
} ],
columnDefs: [ {
orderable: false,
className: 'select-checkbox',
targets: 0
} ],
select: {
style: 'os',
selector: 'td:first-child',
style: 'multi'
},
order: [[ 2, 'asc' ]]
} ).on( 'buttons-action', function ( e, buttonApi, dataTable, node, config ) {
// action put here
console.log( 'Button '+buttonApi.text()+' was activated' );
} );;
} );
So using datatables I was able to get the selected row count. From that I parse the object through a loop for the first row entries.
Finally I call on the reduced array for the position value that I want (in this case position 1 is my Record ID field, more if you want) and push it to a new array.
From that you submit to your traditional controller for processing.
Hope this helps those trying to pass selected Row Data
