How can i grab an element from a row on a datatable?

I have a simple datatable that shows some JSON data, received from an API endpoint.
I added a column that will hold a button on each row of the table. This button, when hit, will fire an AJAX request with the value of id for that specific row.
This actual code works, but now, instead of only sending the value of id, i would also like to edit the table so that, when the button is hit, it will send the values of id and item for that row. Can someone give me some piece of advice on how to do that?
On another question, i've been told to use Data Attributes, but i don't really know how would i integrate this into my current code. Any advice is appreciated.
$(document).ready(function() {
$(document).on('click', '.btnClick', function() {
var statusVal = $(this).data("status");
console.log(statusVal)
callAJAX("/request_handler", {
"X-CSRFToken": getCookie("csrftoken")
}, parameters = {
'orderid': statusVal
}, 'post', function(data) {
console.log(data)
}, null, null);
return false;
});
let orderstable = $('#mytalbe').DataTable({
"ajax": "/myview",
"dataType": 'json',
"dataSrc": '',
"columns": [{
"data": "item"
}, {
"data": "price"
}, {
"data": "id"
},],
"columnDefs": [{
"targets": [2],
"searchable": false,
"orderable": false,
"render": function(data, type, full) {
return '<button type="button" class="btnClick sellbtn" data-status="replace">Submit</button>'.replace("replace", data);
}
}]
});
});

You could use the full parameter of the DataTables render function to store the values of the current seleceted row. In this way:
return '<button type="button" class="btnClick sellbtn" data-status="' + btoa(JSON.stringify(full)) + '">Submit</button>';
In the above code, the data-status data attribute will contains the stringified version of the current object value in base64 by using btoa(). In base64 because for some reason we cannot directly store the stringified version of the object in the button's data attribute.
Then, in the button's click event, you have to do:
Decode the stringified object by using atob().
Parse into object by using JSON.parse().
Something like this:
$(document).on('click', '.btnClick', function() {
var statusVal = $(this).data("status");
// Decode the stringified object.
statusVal = atob(statusVal);
// Parse into object.
statusVal = JSON.parse(statusVal);
// This object contains the data of the selected row through the button.
console.log(statusVal);
return false;
});
Then, when you click in the button you will see this:
So, now you can use this object to send in your callAJAX() function.
See in this example:
$(function() {
$(document).on('click', '.btnClick', function() {
var statusVal = $(this).data("status");
// Decode the stringified object.
statusVal = atob(statusVal);
// Parse into object.
statusVal = JSON.parse(statusVal);
// This object contains the data of the selected row through the button.
console.log(statusVal);
return false;
});
let dataSet = [{
"id": 1,
"item": "Item 1",
"price": 223.22
},
{
"id": 2,
"item": "Item 2",
"price": 243.22
},
{
"id": 3,
"item": "Item 3",
"price": 143.43
},
];
let orderstable = $('#myTable').DataTable({
"data": dataSet,
"columns": [{
"data": "item"
}, {
"data": "price"
}, {
"data": "id"
}, ],
"columnDefs": [{
"targets": [2],
"searchable": false,
"orderable": false,
"render": function(data, type, full) {
// Encode the stringified object into base64.
return '<button type="button" class="btnClick sellbtn" data-status="' + btoa(JSON.stringify(full)) + '">Submit</button>';
}
}]
});
});

Datatable send current page number

I've been try to send current page number to server by overwrite a variable called pgno
here is my code :
function fill_datatable(status='',pgno='')
{
var pgno = 0;
table = $('.tb_scoin_available').DataTable({
"processing": true,
"serverSide": true,
"ordering" : false,
"infoCallback": function( settings, start, end, max, total, pre ) {
var api = this.api();
var pageInfo = api.page.info();
pgno = pageInfo.page+1;
return pgno;
},

],
});
}
when I try to alert on infoCallback :
alert(pgno) the variable already overwrited, but when I try to dump the request on backend the pgno POST give me null result like this :
Anyone can help me out ?

You can get the table page with the page() function, no need for the whole "page.info". It's better explained in Datatable's API: https://datatables.net/reference/api/page()
The method you're trying to access is only to get the information, not to set it. That is probably why it isn't working. Check their docs for better understanding of their API: https://datatables.net/reference/api/page.info()
EDIT:
You can get the current page through a simple calculation. Since you're using serverSide processing, you already have start and length. You just need to do start/length + 1 and you will get the current page number.

Adding an element within a td in jQuery datatable

I have a js data table that I have implemented for pagination of data. It uses the jQuery data table. The data is being displayed correctly. However, I want to add an element within the first row of the data table.
Before I added it like this : <td>#Html.ActionLink(item.CarId, "Detail", "Cars", new { id = item.CarId},null)
<span class="dt-expand-btn js-expand-btn">+</span></td>
What I want to add within the td of the js is : <span class="dt-expand-btn js-expand-btn">+</span>
var carsDataTable = $('.js-cars-lists').DataTable({
"ajax": {
"url": "/Cars/CarsPagination",
"processing": true,
"serverSide": true,
"language": {
"paginate": {
"previous": '<i class="material-icons">chevron_left</i>',
"next": '<i class="material-icons">chevron_right</i>'
}
},
"order": [0, "asc"],
"type": "POST",
"datatype": "json"
},
"columns": [
{
"data": "CarId", "name": "CarId", "autowidth": true,
"render": function (data, type, row, meta) {
$(row.CarId).css('color', 'red');
return '' + row.CarId + '';
}
},
{ "data": "CarName", "name": "CarName", "autowidth": true },
Could someone please help me to achieve this ? Also, paginate icons are not appearing. Please help.

jQuery DataTable has a function of render it accepts 4 parameters function(data, type, row) which you can control the rendering of your rows. You can now check the rows of a table and add your element in it.

You can use columnDefs method and then render:
...
columnDefs: [{
"render": function(data, type) {
return '<span class="dt-expand-btn js-expand-btn">+</span>';
},
"targets": 0
}]
...
targets refers to the index of the table column (since you are referring to the 1st column) set it to 0

Jquery Datatables Checkbox selected append to input field

the btnSearchName will open a Modal with table of the search result, then it has checkbox per row to select, then after I click the btnSubmit, the Modal will close and must put the selected ssn_or_tin column in an input field like '123, 645, 936, 743', I already tried many codes but not working, please help
$('#btnSearchName').on("click", function() {
Namestable = $('#NamesDatatable').DataTable({
"processing": true,
'select': {
'style': 'multi'
},
'order': [[1, 'asc']],
dom: "<'row'<'col-sm-6'l><'col-sm-6'f>>" +
"<'row'<'col-sm-12'tr>>" +
"<'row'<'col-sm-6'i><'col-sm-6'p>>",
"ajax": {
"url": '/Home/GetAllCusname',
"type": "POST",
"datatype": "json",
"data": function (d) {
d.searchParameters = {};
d.searchParameters.name = $('#txtName').val();
}
},
"columns": [
{
defaultContent: '',
className: 'select-checkbox',
'checkboxes': {
'selectRow': true
},
orderable: false
},
{ "data": "ssn_or_tin", "autoWidth": true },
{ "data": "name", "autoWidth": true }
]
});
});
$('#btnSubmit').on("click", function () {
var rows_selected = Namestable.column(0).checkboxes.selected(); //i have not tested this line of code yet if it's working,
maybe there is another way of getting the selected checkbox, maybe by their class if they have the 'selected' class
$.each(rows_selected, function () {
$('#txtSSNTIN').append(
//I don't know what code to put here, it must append the
'ssn_or_tin' values like '123, 953, 673' in the input field with
the id 'txtSSNTIN'
);
});
});

You could have try Onrowbound in DataTable. You dont have to specify these things

Post row datas from DataTable to an Ajax Form

I have a set of JSON data that are displayed using datatables. In one of the columns, I add a button and a text box only if the value in that column and another column meets a certain condition. this is the bit of code I used to do this:
$(document).ready(function (){
var alertTable = $('#alert-table').DataTable({
"jQueryUI": true,
"order": [ 3, 'desc' ],
"columns": [
{ "data": "source", "visible": false },
{ "data": "host" },
{ "data": "priority" },
{ "data": "ack", "render": function( data, type, row ) {
if (row.ack == "0" && row.priority > "2") {
return '<form><input class="ackname" type="text" value="Enter your name"><input class="ackbutton" type="button" value="Ack Alert" onclick="<get all items for that row and POST to a URL>"></form>';
}
return data;
}
},
],
"language": {
"emptyTable": "No Alerts Available in Table"
}
});
});
This works fine by adding a button and text in the cell. What I am looking to achieve is, when any of the button is been clicked, it should POST all the values for that row including what is typed in the text box to a URL which has another function that would extract those details and update the database and send back the refreshed data. I am new to datatables and jquery, any guide would be highly appreciated.

Have made some changes to the code, instead of form you can use div.
$(document).ready(function (){
var alertTable = $('#alert-table').DataTable({
"jQueryUI": true,
"order": [ 3, 'desc' ],
"columns": [
{ "data": "source", "visible": false },
{ "data": "host" },
{ "data": "priority" },
{ "data": "ack", "render": function( data, type, row ) {
if (row.ack == "0" && row.priority > "2") {
return '<div><input class="ackname" type="text" value="Enter your name"><input class="ackbutton" type="button" value="Ack Alert"></div>';
}
return data;
}
},
],
"language": {
"emptyTable": "No Alerts Available in Table"
}
});
$(document).on("click",".ackbutton",function() {
var currentIndex = $(this).parent().parent().index();
var rowData = alertTable.row( index ).data();
//extract the textbox value
var TextboxValue = $(this).siblings(".ackname").val();
var objToSave = {}; //Create the object as per the requirement
//Add the textbox value also to same object and send to server
objToSave["TextValue"] = TextboxValue;
$.ajax({
url: "url to another page"
data: JSON.stringify({dataForSave : objToSave}),
type: "POST",dataType: "json",
contentType: "application/json; charset=utf-8",
success: function(datas) {
//Your success Code
},
error: function(error) {
alert(error.responseText);
}
});
});
});
Since both the pages are in same project, you can also do it using single ajax, passing all the values to server at once and then calling the other page internally from server and passing in the values using query string.
This is not a running code, rather to give you a basic idea on how to proceed.
Hope this helps :)
