Edit DataTables source data, using form inside pop-up window

I have a datatable that fetches records from database with ajax. I want to add the edit tooltip like jquery-datatables-editor extension to datatables but for free. Is there any plugin to do this? if not, can any one help me to do this manually?
This is my JavaScript code:
$('#table_id').DataTable({
"serverSide": true,
"processing": true,
"ajax": function (data, callback, settings) {
$.ajax({
url: '/some url',
type: 'GET',
data: data,
success: function (data) {
console.log(data)
}
});
},
"columns": [{
"title": "edit",
"data": null,
"className": "center",
"defaultContent": ' Edit / Delete '
}, {
"title": "name",
"data": "name"
}, {
"title": "id",
"data": "id"
},
]
});

Since your question (and posted code sample) are mostly concerned with front-end part of editable rows feature I will focus on that primarily as backend logic is pretty much straightforward (update/insert data into storage upon AJAX-request receipt).
In order to implement that feature following logic I may suggest:
append (by means of createdRow option) some anchor (row().index() or source object id property, etc) to your source data within some <tr> attribute (e.g. rowindex), so you will know later on which entry to modify server-side:
$('table').DataTable({
...
createdRow: (tr, _, rowIndex) => $(tr).attr('rowindex', rowIndex)
})
append some anchor attribute (e.g. data-src) to your editor pop-up (I'll use bootstrap-4 modal for that purpose) <input> nodes to link those input fields to corresponding source object properties:
<div><label>PropertyX:</label><input data-src="propertyX"></input></div>
upon clicking edit button, grab corresponding row data, populate editor pop-up <input> fields with that data, pass anchor to edited row (rowindex attribute value) over to pop-up attribute:
//for table id 'example' handle clicking
//edit button having class 'edit'
$('#example').on('click', '.edit', function () {
//get clicked row invoking row() API method
//against DataTables object assigned to dataTable
const rowClicked = dataTable.row($(this).closest('tr'));
//populate edit form with row data by corresponding
//rowClicked property based on 'data-src' attribute
$.each($('#editform input'), function () {
$(this).val(rowClicked.data()[$(this).attr('data-src')]);
});
//set modal attribute rowindex to corresponding row index
$('#editform').attr('rowindex', rowClicked.index());
//open up edit form modal
$('#editform').modal('toggle');
});
upon completing row data editing, store <input> values into object:
const modifiedData = {};
$.each($('#editform input'), function(){
Object.assign(modifiedData, {[$(this).attr('data-src')]:$(this).val()});
});
POST data (along with corresponding rowindex) to the server and reload (ajax.reload()) up-to-date datatable upon success:
$.ajax({
url: '/editrow',
method: 'POST',
data: {id: $('#editform').attr('rowindex'), ...modifiedData},
success: () => {
$('#editform').modal('hide');
dataTable.ajax.reload();
}
});
Complete live demo of that method you might examine in your browser's DevTools by the following link with some bonus in form of row delete button.
Both HTML and jQuery code sample might look as follows (not executable as there's no supporting backend):
$(document).ready(() => {
//data table initialization
const dataTable = $('#example').DataTable({
ajax: {
url: '/getdata',
type: 'GET',
dataSrc: ''
},
dom: 't',
//use <tr> attribute 'rowindex' to anchor to source data row index
createdRow: (tr, _, rowIndex) => $(tr).attr('rowindex', rowIndex),
columns: [
{data: 'name', title: 'Name'},
//append 'Edit'/'Delete' buttons to the rightmost edge of the cell
{data: 'title', title: 'Title', render: (cellData, _, __, meta) => cellData+'<i class="delete fa fa-trash"></i><i class="edit fa fa-pencil"></i></button>'}
],
});
//delete button handler
$('#example').on('click', '.delete', function() {
//extract the index of the row to delete
//from 'rowindex' attribute
const rowIndex = $(this)
.closest('tr')
.attr('rowindex');
//do AJAX-call to the backend
$.ajax({
url: '/deleterow',
method: 'DELETE',
data: {id: rowIndex},
//re-draw datatable with up to date data
success: () => dataTable.ajax.reload()
});
});
//edit button handler (open up edit form modal)
$('#example').on('click', '.edit', function(){
//get clicked row
const rowClicked = dataTable.row($(this).closest('tr'));
//populate edit form with row data by corresponding
//rowClicked property based on 'data-src' attribute
$.each($('#editform input'), function(){
$(this).val(rowClicked.data()[$(this).attr('data-src')]);
});
//set modal attribute rowindex to corresponding row index
$('#editform').attr('rowindex', rowClicked.index());
//open up edit form modal
$('#editform').modal('toggle');
});
//submit edits handler
$('#editform').on('click', '#submitedits', function(){
//grab modified data into object
const modifiedData = {};
$.each($('#editform input'), function(){
Object.assign(modifiedData, {[$(this).attr('data-src')]:$(this).val()});
});
//send modified data to the backend
$.ajax({
url: '/editrow',
method: 'POST',
data: {id: $('#editform').attr('rowindex'), ...modifiedData},
success: () => {
//close the modal
$('#editform').modal('hide');
//re-draw datatable
dataTable.ajax.reload();
}
});
});
});

If you mean JQUERY DATATABLE then you can insert input fields (that would still retain the cell data) for every column within your table row as you desire and set the borders of the input field to not display, with css.
EXAMPLE TABLE
<style>
.no-input-border {
border: 'none' !important; background: 'none' !important;
}
</style>
<table id="dynamic_table">
<thead>
<tr>
<th>Name</th>
<th>State</th>
<th>Address</th>
<th>Active</th>
<th>Action</th> <!-- This column would hold your buttons -->
</tr>
</thead>
<tbody>
</tbody>
</table>
EXAMPLE DATATABLE INITIALIZATION
var table = $('#dynamic_table').DataTable({
"order":[[ 0, 'asc' ]], // order by first column
"processing": true,
'paging': true,
'searching': true,
'retrieve': true,
'serverSide': true,
'ajax': {
'url': "your-ajax-url",
'type': 'POST'
},
'columns': [ //every **name:** value must be present in your json
{ data: null, name: 'name'},
{ data: null, name: 'state' },
{ data: null, name: 'address' },
{ data: null, name: 'active' },
{ data: null, name: 'id' } // column that holds your buttons
],

"targets": 0, // column that inserts an input field
"data": 'name',
"orderable": false,
"createdCell": function (td, cellData, rowData, row, col){
return '<input type="text" class="no-input-border" name="name" value="'+cellData+'" />'
}
},
{
"targets": 1, // column that inserts an input field
"data": 'state',
"orderable": false,
"createdCell": function (td, cellData, rowData, row, col){

'responsive': true,
'initComplete': function(settings, json) {
//Run a function when table first initializes
},
'drawCallback': function( settings ) {
//Run a function anytime table reloads when paginating
}
});
EXAMPLE DATATABLE ROW EDIT FUNCTION
$('#dynamic_table tbody').on('click', '.edit_row', function () {
var row = table.row( $(this).parents('tr') ); // row that was clicked
var d = row.data(); // data of the row button that was clicked .eg. console.log(d.name)
var index = row.index();
var json = { // json to be sent
id: d.id,
name: table.cell(index,0).nodes().to$().find('input').val(),
state: table.cell(index,1).nodes().to$().find('input').val(),
address: table.cell(index,2).nodes().to$().find('input').val(),
active: table.cell(index,3).nodes().to$().find('input').val()
}
/*Your Ajax Function Here*/
});
RELOAD DATATABLE FUNCTION
table.ajax.reload( function ( json ) {
//Run function after table reloads
});

You can create a custom button in datatable. You can go to this documentation to know how it works. Now in the action you can call some function inside it when the user click it the button will call the function in javascript and do what you want inside it.
Here's example code.
$('#table_id').DataTable({
"serverSide": true,
"processing": true,
"ajax": function (data, callback, settings) {
$.ajax({
url: '/some url',
type: 'GET',
data: data,
success: function (data) {
console.log(data)
}
});
},
buttons: [
{ text: 'Add', name: 'btnAdd', action: function ( e, dt, node, config ) {
$.fn.addfunction();
}},
{ extend: 'selected', text: 'Edit', name: 'btnEdit', action: function ( e, dt, node, config ) {
$.fn.editfunction();
}},
{ extend: 'selected', text: 'Delete', name: 'btnDelete', action: function ( e, dt, node, config ) {
$.fn.deletefunction();
}},
],
"columns": [{
"title": "edit",
"data": null,
"className": "center",
"defaultContent": ' Edit / Delete '
}, {
"title": "name",
"data": "name"
}, {
"title": "id",
"data": "id"
},
]
});
$.fn.addfunction = function(){
//Your code here
}
$.fn.editfunction = function(){
//Your code here
}
$.fn.deletefunction = function(){
//Your code here
}
I added the idea of this document from datatables that create custom button and create and call function in jquery
There's also other way by using and giving id for the button. here's the example:
$('#table_id').DataTable({
"serverSide": true,
"processing": true,
"ajax": function (data, callback, settings) {
$.ajax({
url: '/some url',
type: 'GET',
data: data,
success: function (data) {
console.log(data)
}
});
},
buttons: [
{ text: 'Add', name: 'btnAdd',
attr:{
id: 'btnAdd'
}},
{ extend: 'selected', text: 'Edit', name: 'btnEdit',
attr:{
id: 'btnEdit'
}},
{ extend: 'selected', text: 'Delete', name: 'btnDelete',
attr:{
id: 'btnDelete'
}},
],
"columns": [{
"title": "edit",
"data": null,
"className": "center",
"defaultContent": ' Edit / Delete '
}, {
"title": "name",
"data": "name"
}, {
"title": "id",
"data": "id"
},
]
});
$(document).on('click', '#btnAdd', function(e)
{
e.preventDefault();
e.stopPropagation();
//your code here
});
$(document).on('click', '#btnEdit', function(e)
{
e.preventDefault();
e.stopPropagation();
//your code here
});
$(document).on('click', '#btnDelete', function(e)
{
e.preventDefault();
e.stopPropagation();
//your code here
});
Sorry for many Edit Hope it helps!

Store selected rows id

I have a datatable loaded from a query from my database. (+/- 10000 records)
The idea is that the user should be able to select multiple records to be later processed
First i thought to add a column with checkbox for the selection then when user is done with all his selection the application keep track of all selected rows then progress to the next step with "Next Button" some where on the page, but after 12 hours of trying i couldn't do it.
Then i thought to make it simpler by adding a button in each row so that every time the user clicks on this button the application save the selected id in a session variable.
<div class="panel-body">
<table id="userTable" class="table display compact order-column">
<thead>
<tr>
<th>Select</th>
<th>Name</th>
<th>City</th>
<th>Phone</th>
<th>Zipcode</th>
</tr>
</thead>
</table>
#section Scripts {
#Scripts.Render("~/bundles/datatable")
<script type="text/javascript">
$(document).ready(function () {
var ids;
var mytable = $('#userTable').DataTable({
"sDom": 'ltipr',
"bServerSide": true,
"ajax": {
"beforeSend": AjaxBegin,
"type": "POST",
"url": '/LocationModifier/UserHistory',

{ "className": "text-center custom-middle-align", "targets": [0, 1, 2, 3, 4, ] },
],
"colReorder": true,
"lengthMenu": [[10, 25, 50, 100], [10, 25, 50, 100]],

"searchable": false,
"sortable": false,
"render": function (data, type, full, meta) {
return '<span class="glyphicon glyphicon-pencil btn-sm btn-info"></span>';
}
},
{ "data": "Name", "orderable": false },
{ "data": "City", "orderable": true },
{ "data": "Phone", "orderable": true },
{ "data": "Zipcode", "orderable": false },
],

});
});
</script>
}
public ActionResult AddToCache(int id)
{
GetRecordAndAddeToCache(id);
// what should i return here, the page should not be refreshed????
}

There's no problem to implement your initial approach:
use some global set that will store selected row id's, like var rowsSelected = new Set();
add/delete id of the row being checked to that global variable upon clicking selection checkbox:
$('.markSelected').on('click', function () {
const selectedRowId = dataTable.row($(this).closest('tr')).data().id;
$(this).prop('checked') ? rowsSelected.add(selectedRow) : rowsSelected.delete(selectedRow);
});
upon table re-rendering append checkboxes to the first column and set those checked if rendered row id is present within rowsSelected:
render: function (data) {
return `<input type="checkbox" ${rowsSelected.has(data.id) ? 'checked' : ''}></input>`;
}
The complete demo, implementing that concept:
//table source
const srcData = [
{id: 1, item: 'apple', cat: 'fruit'},
{id: 2, item: 'pear', cat: 'fruit'},
{id: 3, item: 'carrot', cat: 'vegie'},
{id: 4, item: 'tomato', cat: 'vegie'},
{id: 5, item: 'cucumber', cat: 'vegie'}
];
//global variable that stores selected item id's
const selectedRows = new Set();
//datatables initialization
const dataTable = $('#mytable').DataTable({
dom: 't',
data: srcData,
columns: [
{data: null, render: function(data){
return `<input class="markSelected" type="checkbox" ${selectedRows.has(data.id) ? 'checked' : ''}></input>`;
}},
{data: 'item', title: 'item'},
{data: 'cat', title: 'cat'}
]
});
//selection checkboxes click handler
$('#mytable').click('.markSelected', function(){
const selectedRowId = dataTable.row($(event.target).closest('tr')).data().id;
$(event.target).prop('checked') ? selectedRows.add(selectedRowId) : selectedRows.delete(selectedRowId);
});
//proceed to the next step with selected row id's
$('#nextStep').on('click', function(){
console.log([...selectedRows]);
});

You can use datatable's Row selection feature to achieve what you are trying to do.
$(document).ready(function() {
var table = $('#userTable').DataTable();
$('#userTable tbody').on( 'click', 'tr', function () {
$(this).toggleClass('selected');
} );
$('#submitButtonId').click( function () {
alert( table.rows('.selected').data().length +' row(s) selected' );
// You can use table.rows('.selected').data() to get all the selected Data
} );
} );

DataTables warning: table id=table_especie - Requested unknown parameter '0' for row 0, column 0

I know this was asked hundreds of times, but I think my case is very specific and it needs someone who knows jQuery to help, or at least has seen this before!
I have this code to build a table called "especie:
HTML
<table class="table" id="table_especie">
<thead>
<tr>
<th></th>
<th></th>
</tr>
</thead>
<tbody>
</tbody>
</table>
Script JS:
var tableEspecie= $('#table_especie').DataTable({
"paging": false,
"info": false,
"order": [
[2, "asc" ],
[3, "asc"],
[1, "asc"]
],
"columnDefs": [
{ "visible": false, "targets": 0 },
{ "visible": false, "targets": 2 },
{ "visible": false, "targets": 3 }
],
"drawCallback": function () {
var api = this.api();
var rows = api.rows( {page:'current'} ).nodes();
var last=null;
api.column(2, {page:'current'} ).data().each( function ( especie, i ) {
if ( last !== especie) {
$(rows).eq( i ).before(
'<tr class="especie info"><td colspan="4">'+especie+'</td></tr>'
);
last = especie;
}
} );
$("#table_especie thead").remove();
$("#table_especie tfoot").remove();
}
});
var populateEspecieShowName = function(data) {
$('#animal_especie_name').text(data[0].name);
};
var populateEspecieTable = function(data) {
var animais = [];
$.each(data, function(id_animal, animal){
animais.push([
animal.id_animal,
animal.nome_animal + ': ' + '<br>' + animal.notas_animal,
animal.foto_animal
]);
});
$('#table_especie').dataTable().fnClearTable();
$('#table_especie').dataTable().fnAddData(animais);
$('#table_especie').dataTable().fnDraw();
};
$('#table_especie tbody').on( 'click', 'tr', function () {
var animalId = $('#table_especie').DataTable().row(this).data();
if (animalId !== undefined)
$.route('animal/' + animalId[0]);
});
$('#table_especie_search').keyup(function(){
$('#table_especie').DataTable().search($(this).val(), false, true).draw() ;
});
Basically, it builds the table using data from a database! And I get the error (DataTables warning: table id=table_especie - Requested unknown parameter '0' for row 0, column 0. For more information about this error, please see http://datatables.net/tn/4) every time I go from table "especies" to table "especie". The error makes it sound like it's something wrong with "especie". What should I change to make the error go away? It still builds the table, but I get this error before. Thanks!!!

Solution:
"columnDefs": [{
"defaultContent": "-",
"targets": "_all"
}],

reload datatable by ajax and json

I'm using datatable plugin and want to refresh table by ajax. I've read here to make my ajax return shows in table but it doesn't work. Here is my html code:
<button type="button" onclick="rld()">test</button>
<table id="sample_1">
<thead>
<tr>
<th> 1 </th>
<th> 2 </th>
<th> 3 </th>
</tr>
</thead>
</table>
My java function:
function rld(){
var table = $('#sample_1').DataTable( {
ajax: '<?php echo site_url('admin/test'); ?>',
deferRender: true,
columns: [
{ data: '1' },
{ data: '2' },
{ data: '3' }
],
rowId: 'extn',
select: true,
dom: 'Bfrtip',
buttons: [
{
text: 'Reload table',
action: function () {
table.ajax.reload();
}
}
]
} );
}
I can't get what the problem is. there in no alerts but in the console i get TypeError: f is undefined
and TypeError: c is undefined
Which i don't know why cause my json return is correct (checked in [JSONLint][3]).
Thanks in advance.

Thank you all for your attention :)
Found that i didn't call where the data goes when returned as json and the json field's name isn't equal to the column data field name. So make this adjustment:
function reload_table(){
var table = $('#sample_1').DataTable();
table.destroy();
var table = $('#sample_1').DataTable( {
"processing": true,
"dataType": 'json',
ajax: '<?php echo site_url('admin/relaod_table'); ?>',
deferRender: true,
columns: [
{ data: 'user_firstname' },
{ data: 'user_lastname' },
{ data: 'user_status' },
{ data: 'user_created_date' },
],
dom: 'Bfrtip',
buttons: [
{
text: 'Reload table',
action: function () {
table.ajax.reload();
}
}
]
} );
}

Why my dataTables in bootstrap don't see the data included?

I want to create a dynamic table in bootstrap/jquery, similar to this one
In this example the data is hardcoded, so I thought about changing it with the data that comes from json. Additionally, each row in table has to have a hyperlink added, so my jquery code is as follows:
$('#dataTables-example').DataTable({
responsive: true
});
var data = '[{"number":"1","id":"2","price":"100.70","date":"2015-10-18 03:00:00","hidden":"21"},
{"number":"2","id":"2","price":"88.20","date":"2015-10-18 04:00:00","hidden":"22"}]';
json = JSON.parse(data);
$.each(json, function(i, v) {
$('<tr/>', {
html: [$('<td/>', {
text: v.number
}), $('<td/>', {
text: v.id
}), $('<td/>', {
text: v.price
}), $('<td/>', {
text: v.date
}), $('<td/>', {
html: [
$('<a/>', {
href: '#',
class: 'show-details',
text: 'show details',
data: { id: v.hidden },
click: function() {
var id = $(this).data('id');
console.log(id);
alert(id);
}
})
]
})]
}).appendTo('#dataTables-example tbody')
})
In my html I hardcoded the header of the table:
<div class="panel-body">
<div class="dataTable_wrapper">
<table class="table table-striped table-bordered table-hover" id="dataTables-example">
<thead>
<tr>
<th>number</th>
<th>id</th>
<th>price</th>
<th>date</th>
<th>show details</th>
<th style="display:none;">hidden identifier</th>
</tr>
</thead>
<tbody></tbody>
</table>
and later on thanks to my script I'm appending rows to the table. Simple as that.
However, as you can see in my fiddle:
http://jsfiddle.net/uo8rc5qL/6/
there is a problem, because since the data is not hardcoded, the table thinks there are no rows and displays the specific message there No data available in table. Also, when I click any column name to sort that data - content disappears, since the table thinks there's nothing to display after sorting...
How can I fix this situation?

This is because you're just adding the data to the table, not the underlying datatable source. The solution is to let datatables handle the loading of the data:
$('#dataTables-example').DataTable({
responsive: true,
"data": JSON.parse(datasrc),
"columns": [
{ data: 'number' },
{data: 'id'},
{data: 'price' },
{ data: "date" },
{
"data": "null",
"defaultContent": "<a>click</a>"
},
{ data: "hidden" }
]
});
Working example: JSFIDDLE

Always go through the API! Insert new rows using table.row.add([..]) instead of the jQuery $('<tr>', {... approach :
$.each(json, function(i, v) {
var row = table.row.add([v.number, v.id, v.price, v.date, '<a>show details</a>']);
table.cells({ row: row.index(), column: 4 }).nodes().to$().find('a')
.attr('href', '#')
.addClass('show-details')
.css('cursor', 'pointer')
.data('id', v.hidden)
.on('click', function() {
var id = $(this).data('id');
console.log(id);
alert(id);
})
table.draw();
})
