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) {
$.ajax({
url: '/some url',
type: 'GET',
data: data,
success: function (data) {
console.log(data)
}
});
},
"columns": [{
"title": "edit",
"data": null,
"className": "center",
"defaultContent": '<a href = "" class = "editor_edit"> Edit </a> / <a href = "" class = "editor_remove"> Delete </a>'
}, {
"title": "name",
"data": "name"
}, {
"title": "id",
"data": "id"
},
]
});
Since your question (and posted code sample) are mostly concerned with front-end part of editable rows feature I will focus on that primarily as backend logic is pretty much straightforward (update/insert data into storage upon AJAX-request receipt).
In order to implement that feature following logic I may suggest:
createdRow
option) some anchor (row().index()
or source object id
property, etc) to your source data within some <tr>
attribute (e.g. rowindex
), so you will know later on which entry to modify server-side:$('table').DataTable({
...
createdRow: (tr, _, rowIndex) => $(tr).attr('rowindex', rowIndex)
})
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>
<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');
});
<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({

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
});
