checkbox not working in data table when paginated

I have a data table using jquery that display a list of data. I implemented a checkbox on the first column that I can check for each record or check all the records at once. If there is one checkbox or more selected then the approve and reject button would show up. While all these can work at the moment but if I select a next page and start checking any checkbox, the approve/reject button will not display.
Code:
<article class="col-xs-6 text-right">
<button id="approveButton" class="btn btn-success update-button" value="1">Approve</button>
<button id="rejectButton" class="btn btn-danger update-button" value="2">Reject</button>
</article>
var $table = $("#dt_basic").DataTable({
"scrollY": ($(window).height() - 270)+"px",
"scrollX": false,
"pageLength": ' . Yii::$app->params['settings']['listing_length'] . ',
"processing": true,
"serverSide": true,
"columnDefs": [{ "targets": [0, 6], "searchable": false, "orderable": false, "visible": true, className: "text-center-desktop" }],
"deferLoading": ' . $total . ',
"order": [],
"ajax": "' . Yii::$app->urlManager->createUrl(['xxxx']) . '",
"sDom": "<\'dt-toolbar\'<\'col-xs-12 col-sm-9\'f><\'col-sm-3 hidden-xs\'l>>r"+
"t"+
"<\'dt-toolbar-footer\'<\'col-sm-5 col-xs-12 hidden-xs\'i><\'col-xs-12 col-sm-7\'p>>",
"autoWidth" : true,
"preDrawCallback" : function() {
responsiveHelper_dt_basic = new ResponsiveDatatablesHelper($(\'#dt_basic\'), {tablet : 1024, phone : 480});
},
"rowCallback" : function(nRow) {
responsiveHelper_dt_basic.createExpandIcon(nRow);
},
"drawCallback" : function(oSettings) {
responsiveHelper_dt_basic.respond();
var pagination = $(this).closest(".dataTables_wrapper").find(".dataTables_paginate");
pagination.toggle(this.api().page.info().pages > 1);
}
});
$("#approveButton").hide();
$("#rejectButton").hide();
$("#masterCheck").on("click", function (e) {
if ($(this).is(":checked", true)) {
$(".subChk").prop("checked",true);
} else {
$(".subChk").prop("checked", false);
}
});
//This would not detect if checkbox is ticked in next page
$("input:checkbox").on("change",function(){
if ($("input:checkbox:checked").length > 0) {
$("#approveButton").show();
$("#rejectButton").show();
} else {
$("#approveButton").hide();
$("#rejectButton").hide();
}
});
$(".update-button").on("click", function(e) {
e.preventDefault();
var status = $(this).val();
let allVals = [];
$(".subChk:checked").each(function() {
allVals.push($(this).attr("id"));
});
console.log(allVals);
let join_selected_values = allVals.join(",");
$.ajax({
url: "updatewithdrawbulk",
type: "UPDATE",
data: {
ids: join_selected_values,
type: status
},
success: function(data) {
location.reload();
},
error: function (data) {
alert("There is some error, please try again");
}
});
});
After going to next page, checking the master checkbox will work (checked all sub checkbox as well) and approve/reject button will show. My only issue is when I tick any checkbox individually, it will not show the buttons.
I was wondering if this is an issue with the code or jquery data table?

The issue is that when you are attaching these .on bindings - it will only attach for the elements that currently exist in the html to be found.
When your next set of rows are drawn - these do not have the events bound to them.
If you hook into the event callback that tells you when new rows have appeared - you should bind your events again so that these new rows work as expected.
In the sample I would expect this to be achieved within the drawCallback event.

how to destroy table and reinitialize same table with new updated data using Datatables Jquery plugin

I am using Datatables plugin and dynmically populating the table with the data returned from server. on different table draws the returned data has variable no of columns. On each table intilization the code is checking if there has been previous initializations and removes it before creating a new table with dynamic data, using this code:
if ( $.fn.dataTable.isDataTable( '#contracts_forecast' ) ) {
$('#contracts_forecast').DataTable().clear();
$('#contracts_forecast').DataTable().destroy();
$('#contracts_forecast tbody').empty();
$('#contracts_forecast thead').empty();
}
On the serverside I am manually editing the data and updating the database. When the database is updated with new data , I want to refresh the table so the change is reflected in the table. In order to do that I am using an POST SUBMIT event, which is triggered after the data is submitted to server and then call the function getDT(filter_product_code, filter_product_name) to update the table with new data
PROBLEM:
When the post submit event is triggered , it recalls the function getDT(filter_product_code, filter_product_name); and change is reflected. BUT THE NEW TABLE with UPDATED IS ADDED TO CURRENT TABLE WITHOUT THE OLD TABLE BEING DESTROYED Which leaves me with two same tables on screen
p.s I am assuming every time getDT() function is called it should check for if table is initialized and destroy it before creating a new one using the same
$(document).ready(function() {
$('#filter').click(function(){
var filter_product_code = $('#filter_product_code').val();
var filter_product_name = $('#filter_product_name').val();
if(filter_product_code == '' || filter_product_name == '')
{
alert('Select Both filter option');
}
var columns = [];
getDT(filter_product_code, filter_product_name);
function getDT(filter_product_code, filter_product_name) {
$.ajax({
serverSide: true,
type:'POST',
url: "/XXX/_fetch.php",
data: {filter_product_code: JSON.stringify(filter_product_code),
filter_product_name: JSON.stringify(filter_product_name)},
success: function (data) {
data = JSON.parse(data);
columnNames = Object.keys(data.data[0]);
for (var i in columnNames) {
columns.push({data: columnNames[i],
title: capitalizeFirstLetter(columnNames[i])});
}
if ( $.fn.dataTable.isDataTable( '#contracts_forecast' ) ) {
$('#contracts_forecast').DataTable().clear();
$('#contracts_forecast').DataTable().destroy();
$('#contracts_forecast tbody').empty();
$('#contracts_forecast thead').empty();
}
table = $('#contracts_forecast').DataTable({
data: data.data,
columns: columns,
dom: "Bfrtip",
select: true,
buttons: [
{ extend: "create", editor: editor },
{ extend: "edit", editor: editor },
{ extend: "remove", editor: editor }
],
"columnDefs": [
{
"targets": [0],
"visible": false,
"searchable": false
},
{ className: "tablecolumns", targets: "_all" },
]
} );
$('#contracts_forecast').on( 'click', 'tbody td:not(:first-child)', function (e) {
editor.inline( this );
} );
}
});
editor.on( 'postSubmit', function ( e, json, data, action, xhr ) {
getDT(filter_product_code, filter_product_name);
});
}
});
} );

I was doing a mistake by declaring the column variable outside function. Each time the function was called it was adding to already existing columns. So just needed to define column variable inside function.
getDT(filter_product_code, filter_product_name);
function getDT(filter_product_code, filter_product_name) {
var columns = [];
$.ajax({
serverSide: true,
// paging: true,
// retrieve:true,
type:'POST',

Is there a way to pull from multiple SQL tables for one DataTables table?

I use DataTables to present data in a reporting website that I created. I am working on creating a Report Builder where users can select multiple tables and then columns from those tables for a custom report.
What I want to know is whether there's a way to do this with DataTables. I'm able to get the tables names and column names for the custom report, but I've not been able to figure out how to send it to DataTables. I currently use server side processing and send an ajax call using POST to the DataTable.
I know that I can program in a SQL query based on the selected tables and columns, but I cannot seem to figure out how to have the data sent to DataTables.
Here is how I initialize my DataTables:
$(document).ready(function ()
{
// Setup - add a text input to each footer cell
$('#DataTable tfoot th').each(function () //creates the search bar as the footer
{
var title = $(this).text();
$(this).html('<input type="text" placeholder="Search ' + title + '" />');
});
var table = $('#DataTable').DataTable({
"lengthMenu": [[25, 50, 75, 100, 150, -1], [25, 50, 75, 100, 150, 'All']],
"dom": '<"top"Bifpl<"clear">>rt<"bottom"ip<"clear">>',
"buttons": [{
extend: 'collection',
text: 'Export',
buttons: ['export', { extend: 'csv',
text: 'Export All To CSV', //Export all to CSV file
action: function (e, dt, node, config)
{
window.location.href = './ServerSide.php?ExportToCSV=Yes';
}
}, 'csv', 'pdf', { extend: 'excel',
text: 'Export Current Page', //Export to Excel only the current page and highlight the first row as headers
exportOptions: {
modifier: {
page: 'current'
}
},
customize: function (xlsx)
{
var sheet = xlsx.xl.worksheets['sheet1.xml'];
$('row:first c', sheet).attr('s', '7');
}
}]
}
],
"fixedHeader": { //Keeps the header and footer visiable at all times
header: true,
footer: true
},
"select": true, //sets the ability to select rows
"processing": true, //shows the "Processing" when working
"serverSide": true, //sends data to the server for processing
"ajax": { //where the data is sent and processed
"url": "./ServerSide.php",
"type": "POST"
},
stateSave: true, //Saves the current state of the page
columnDefs: [{ visible: false, targets: 0}], //Hides the first column the ID column
initComplete: function () //sets the search
{
var api = this.api();
// Apply the search
api.columns().every(function ()
{
var that = this;
$('input', this.footer()).on('keyup change', function (e)
{
if (that.search() !== this.value & e.keyCode == 13) //you have to hit enter for the search to start
{
that
.search(this.value)
.draw();
}
});
});
}
});
});
$.fn.dataTable.ext.buttons.export =
{
className: 'buttons-alert', //Adds the "Export all to Excel" button
id: 'ExportButton',
text: "Export All To Excel",
action: function (e, dt, node, config)
{
window.location.href = './ServerSide.php?ExportToExcel=Yes';
}
};
Here is what I can currently get to work:
I'm not sure else anyone would need to help me with this, but if I'm missing something let me know and I'll add it.
I need all the data from all selected tables and columns to be in one DataTables table presented on the website. In the image above I'm showing that I've gotten as far as getting the column headers and using aliases for the tables. I'm working through my FilterSort.class.pph file (which is like the ssp.class.php in DataTables) to see if I can get it to present the table.

I figured it out. I was still calling the correct DataTables functions, but I wasn't passing the data to the functions. I ended up having to update my ServerSide.php file and my FilterSort.class.php file. Those are the ones that all of the other reports use to send data from the server to the screen. After some trial and error, I got it to work and didn't need to change anything in the code posted in my question.

how to append json array in datatable using render function

I want to append json array into one popover attribute called data-content.
I am using jQuery DataTables plugin to perform UI functionalities. Using data variable table is populated with the data.
How could I insert titleDescription array from data variable into the attribute name called as data-content inside a tag in js , check my fiddle and go to datatable function there inside columnDefs there is render function. In that function I have return and append a tag, there only I have to append titleDescription array.
Check this JSFiddle for demonstration.

You can use the row attribute, and have the data in a non visible column.
Check the example
https://datatables.net/examples/advanced_init/column_render.html
$(document).ready(function() {
$('#example').DataTable( {
"columnDefs": [
{
// The `data` parameter refers to the data for the cell (defined by the
// `data` option, which defaults to the column being worked with, in
// this case `data: 0`.
"render": function ( data, type, row ) {
return data +' ('+ row[3]+')';
},
"targets": 0
},
{ "visible": false, "targets": [ 3 ] }
]
} );
} );
That would do the trick.

You just need to add another column at the last of each row then you can access it from row like this
render : function(data, type, row) {
return '<span class="favlist-icon"></span><span class="immediate-attention-icon"> </span> <span class="docx-name-list-link"> <a class="apopoverdata" href="#" data-content="'+row[4]+'" rel="popover" >'+data+'</a></span>';
}
Here is working fiddle
https://jsfiddle.net/2cn4b8bz/4/

I'm not sure what library you were using for your pop over so I used tooltipster seeing as you had jQuery already for the DataTable. Your data didn't have everything you needed either so I've altered it a wee bit:
$(function() {
$('#documentListing-data').DataTable({
data: json.documentAll.document,
pageLength: 10,
columns:[
{
"data": "documentTitle",
"title": "Name",
"render": (data, type, row) => '' + data + '',
},
{
"data": "category",
"title":"Category",
"render": (data, type, row) => data.map((k, v) => k.trim()).join(", "),
},
{
"data": "publishedDate",
"title":"Published Date"
},
{
"data": "lastUpdatedDate",
"title": "Last Updated Date"
},
],
"drawCallback": function(settings) {
$('.tooltip').tooltipster();
}
});
});
Working JSFiddle. Hope that helps!

Javascript keyword "this" becomes undefined

I am using DataTables to create a list of selectable phone numbers, my function is as follow:
function search(areacode) {
areacode = typeof areacode !== 'undefined' ? areacode : 239;
$("#did_search").fadeIn();
var table = $('#example').DataTable( {
"bDestroy": true,
"ajax": "/Portal/manage/search_bulkvs/" + areacode,
"columns": [
{ "data": "did" },
{ "data": "city" },
{ "data": "state" },
{ "data": "action" },
],
"columnDefs": [
{ "visible": false, "targets": 3 }
]
} );
$('#example tbody').on( 'click', 'tr', function () {
var row_object = table.row( this ).data();
$("label[for = did_label]").text(row_object.action);
$('input[name="did"]').val(row_object.action);
} );
}
The end of the function $('#example tbody') -- allows me to select the data from the table that I need and set the value of my label/input for form processing. However, after I run this function a second time I am unable to select this data anymore.
My debugging has led to this error: Uncaught TypeError: Cannot read property 'action' of undefined
I thought that row_object would be defined every time that the function is run, but it looks like it isnt.
Does anyone have any suggestions as to how I can retrieve this data from the table after the function has been run more than once?

If the ajax call replaces the tbody element of the table, you will need to attach your delegated event handler to a non-changing ancestor (e.g. $('#example').on or even $('#example').parent().on(.
You also want to avoid repeatedly setting up handlers if search is called multiple times (or call off before on).
e.g.
$('#example tbody').off('click').on( 'click', 'tr', function () {
var row_object = table.row( this ).data();
$("label[for = did_label]").text(row_object.action);
$('input[name="did"]').val(row_object.action);
} );

Since you're using ajax, you need to bind your click object on each draw using DataTables.fnDrawCallback, like this:
function search(areacode) {
areacode = typeof areacode !== 'undefined' ? areacode : 239;
$("#did_search").fadeIn();
var table = $('#example').DataTable( {
"bDestroy": true,
"ajax": "/Portal/manage/search_bulkvs/" + areacode,
"columns": [
{ "data": "did" },
{ "data": "city" },
{ "data": "state" },
{ "data": "action" },
],
"columnDefs": [
{ "visible": false, "targets": 3 }
],
"fnDrawCallback": function(){
$("tbody tr td",$(this)).click(function(e){
.... Your click code here ....
});
}
} );
}

It is not that this becomes undefined. This error message
Uncaught TypeError: Cannot read property 'action' of undefined
usually means that you are calling a function from an undefined object (here is row_object), or the function you are calling (action) is not on the object.
Yes, the definition of variable row_object is fine. But I think you can console.log it to see whether it is assigned to some value correctly every time.
