I'm developing with django and javascript with datatable.
I want to apply column filtering in my datatable
(https://datatables.net/extensions/fixedheader/examples/options/columnFiltering.html)
but it works fine without serverside option & ajax (in client side),
but it doesn't work with serverside option & ajax.
How can i FIX IT? Please help me..
this is my code.
<table id="sample_table" class="table table-bordered table-hover">
<thead>
<tr>
<th class="sample_id">ID</th>
<th>date</th>
<th>serial</th>
<th>name</th>
<th>birth</th>
</tr>

<tr>
<th>ID</th>

</tr>
</tfoot>
</table>

{ "data" : "receiving_at" },
{ "data" : "serialnumber" },
{ "data" : "name" },
{ "data" : "birthday" },
];
$('#sample_table tfoot th').each(function(){
var title = $("#sample_table thead th").eq( $(this).index() ).text();
$(this).html('<input type="text" placeholder="Search '+title+'" />' );
});
var sample_table = $('#sample_table').DataTable({

Controller load the view and load the jQuery.
index.blade.php
<table id="UserGrid" class="table table-bordered table-striped">
<thead>
<tr>
<th>ID</th>
<th>Name</th>
<th>Country</th>
<th>Dept</th>
<th>Title</th>
<th>Username</th>
<th>Role</th>

#php
$pageJsScript = array(
'<script type = "text/javascript" src="js/setting/user/User_search.js")></script>'
);
$pageJsCalls = array(
'User_search.init();'
);
#endphp
The above code is in between the <section> tags
In my master page I call these functions:
<?php foreach ($pageJsScript as $jsScript)
{
echo $jsScript.PHP_EOL;
}
?>
<script>
jQuery(document).ready(function() {
Apps.init();
<?php foreach ($pageJsCalls as $jsCall)
{
echo $jsCall.PHP_EOL;
}
?>
});
</script>
And the then I created a separated file kept in JS folder:
var User_search = function () {
var DataGrid = $('#UserGrid');
var loadGridUrl = "{{url('/show_user_list')}}";
var dataTable = null;
var loadGrid = function () {
alert('called');
var url = loadGridUrl;
dataTable = DataGrid.DataTable({

return '<span class="label label-danger label-sm">Locked</span>';
}
}
},
{data: "created_at"},
{
data: null, render: function (data, type, row) {
// Combine the first and last names into a single table field
if(user_id==1 || user_id==21) {
return '<i class="fa fa-edit"></i> Edit' +
'| <i class="fa fa-trash-o"></i> Delete';
}else {
return '';
}
}
},
],
});
$("#UserGrid_tools > li > a.tool-action").on("click", function () {
var e = $(this).attr("data-action");
dataTable.button(e).trigger();
});
$(".dt-buttons").hide();
jQuery('#UserGrid_wrapper .dataTables_filter input').addClass("form-control input-small"); // modify table search input
jQuery('#UserGrid_wrapper .dataTables_length select').addClass("form-control input-small"); // modify table per page dropdown

}
return {
//main function to initiate the module,
init: function () {

if (!jQuery().dataTable) {
return;
}
loadGrid();
},
};
}();
Kindly guide me in order to get run all things, infact alert is working by the function loadGrid() is not working.

I have jQuery datatables with some checkboxes for granting privileges.
I need to get table values to a array. Please enlighten me about how to get checkbox states inside cells, not only the checked ones. Thank you.
My table
<table id="jqueryTable" name="tt" class="table table-striped table-bordered" cellspacing="0">
<thead>
<tr>
<th name="id">
ID
</th>
<th name="name">
PRIV_Name_Str
</th>
<th name="create">
Create
</th>
<th>
Edit
</th>
<th>
View
</th>
</tr>
</thead>
<table>
My datatable query
function LoadProduct(element) {
$.ajax({
url: '/ADM_MAS_Privilege/GetFormData',
data: { YourValue: $('#productCategory').val() },
method: 'post',
dataType: 'json',
success: function (data) {
var table = $('#jqueryTable').dataTable({
paging: true,
sort: true,
searching: true,
scrollY: 200,
data: data,
bDestroy: true,
"columnDefs":
[{
"targets": [2, 3, 4],
"render": function (data, type, row, meta) {
console.log("XX " + meta.row + " " + meta.col);
return type === 'display' ?
'<input type="checkbox" id="p" class="chk" name="group' + meta.row + '" /> ' + data :
data;
columns: [{ "data": "ID", "ID": "ID", "autoWidth": true },
{
"data": "PRIV_Name_Str", "PRIV_Name_Str": "PRIV_Name_Str", "autoWidth": true
},
{
"data": "Create", "Create": "Create", "autoWidth": true
},
{ "data": "Edit", "Edit": "Edit", "autoWidth": true },
{
"data": "View"
}
]
});
}
});
};
My jQuery function to read datatable
$('#upload').click(function () {
var table = document.getElementById("jqueryTable");
var tableArr = [];
for (var i = 1; i < table.rows.length; i++) {
tableArr.push({
ID: table.rows[i].cells[0].innerHTML,
PRIV_Name_Str: table.rows[i].cells[1].innerHTML,
Create: table.rows[i].cells[2].innerHTML,
Edit: table.rows[i].cells[3].innerHTML,
View: table.rows[i].cells[4].innerHTML
});
}
});
I tried table.rows[i].cells[2].innerHTML.getElementById("p").checked even and it's not working.
Since you are using jQuery:
document.getElementById("jqueryTable").each(function (index, element) {
tableArr.push({
ID: element.cells[0].innerHTML,
PRIV_Name_Str: element.cells[1].innerHTML,
Create: element.cells[2].innerHTML,
Edit: element.cells[3].innerHTML,
View: element.cells[4].innerHTML
})
})
You can find the element and the checked property within each cell:
for (var i = 1; i < table.rows.length; i++) {
var cells = table.rows[i].cells;
tableArr.push({
ID: cells[0].innerHTML,
PRIV_Name_Str: cells[1].innerHTML,
Create: cells[2].querySelectorAll('input')[0].checked,
Edit: cells[3].querySelectorAll('input')[0].checked,
View: cells[4].querySelectorAll('input')[0].checked
});
}
I'm using datatable to show data from controller (i'm using Codeigniter) and need to show number column on the left table column.
I have tried:
$(document).ready(function() {
$('#booking_table').dataTable( {
processing: true,
serverSide: true,
language: dt_lang,
pagingType: "simple",
dom: 't<"col-sm-3 text-left"l><"col-sm-3"i><"col-sm-2"r><"col-sm-4 text-right"p>',
autoWidth : true,
ajax: {
"url" : base_url+"book/ajax_history",
"type" : "POST",
data : function (d){
d.show_filter = $('#_show_filter').val();
d.view_type = $('#_view_type').val();
}
},
columns: [
{
data : "b.booking_id",
visible : false,
},
{ data : null}, //where i should put index number
{ data : 'b.booking_date', className : "hidden-xs"},
{ data : 'b.from_name', className : "hidden-xs"},
{ data : 'b.to_name'},
],
responsive: false
});
// reference the table in a variable
var table = $('#booking_table').DataTable();
table.on( 'order.dt search.dt', function () {
table.column(0, {
search:'applied',
order:'applied'
}).nodes().each( function (cell, i) {
cell.innerHTML = i+1;
} );
} ).draw();
My Table:
<table class="table table-condensed" id="booking_table">
<thead>
<tr>
<th class="hidden-xs">id</th>
<th>No</th>
<th class="hidden-xs">
Tanggal
</th>
<th class="hidden-xs">
Pengirim
</th>
<th>
Penerima
</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
Refer to this https://www.datatables.net/examples/api/counter_columns.html
but, it's not working. What am I doing wrong ?
Please try below mentioned solution. Hope this will help you. Actually you initialized datatable two times.
$(document).ready(function() {
var table = $('#booking_table').dataTable({
processing: true,
serverSide: true,
language: dt_lang,
pagingType: "simple",
dom: 't<"col-sm-3 text-left"l><"col-sm-3"i><"col-sm-2"r><"col-sm-4 text-right"p>',
autoWidth: true,
ajax: {
"url": base_url + "book/ajax_history",
"type": "POST",
data: function(d) {
d.show_filter = $('#_show_filter').val();
d.view_type = $('#_view_type').val();
}
},
columns: [{
data: "b.booking_id",
visible: false,
},
{
data: null
}, //where i should put index number
{
data: 'b.booking_date',
className: "hidden-xs"
},
{
data: 'b.from_name',
className: "hidden-xs"
},
{
data: 'b.to_name'
},
],
responsive: false
});
table.on('order.dt search.dt', function() {
table.column(0, {
search: 'applied',
order: 'applied'
}).nodes().each(function(cell, i) {
cell.innerHTML = i + 1;
});
}).draw();
});
I am using DataTables to generate a table. There is a column containing order numbers.
For example:
...
I need every row in this column to have a hyperlink to view/order?id=? where ? is the contents of row in the Order No column. For example the first row would be a hyperlink to view/order?id=1321755 etc.
What is the simplest way I can do so?
Here is the code that I am using to initialize the DataTables:
<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
$('#example').dataTable( {
"serverSide": true,
"ajax": {
"url": "../server_processing/orders.php",
"type": "POST"
},
"order": [[ 0, "desc" ]]
} );
} );
</script>
<table id="example" class="display" cellspacing="0" width="100%">
<thead>
<tr>
<th>Order No</th>
...
</tr>
</thead>
<tbody>
</tbody>
</table>
Check this out:
http://datatables.net/reference/option/columns.render
You can add a column render callback when you specify columns definition.
var columnsDef = [
...
{
"title": "Order No.",
"render": function (data, type, row, meta) {
return '' + data + '';
}
},
...
];
$("#table").dataTable({
...
"columns": columnsDef,
...
});
The data in that column will be changed to what the render function return.
I needed to use jQuery dataTables and turn a normal field to be a HREF field.
Here you have it all, including also dataTables error handling..
Enjoy..

1) The HTML part:
<!-- COMPANIES LIST start -->
<div id="compListDiv" style="visibility:hidden; position : absolute; left : 360px; top : 40px;">
<br>
<table id="compList" align="left" border="1">
<thead>
<tr>
<th>id</th>
<th>name</th>
<th>address</th>
</tr>
</thead>
</table>
</div>
<!-- COMPANIES LIST end -->
2) The javascript dataTables part:
When a button is clicked the following js function is called:
function companiesList(){
accountstable=$('#compList').dataTable({
sort : true,
bFilter: false,
bInfo: false,
paging:false,
autoWidth: true,
ajax: {
url: "http://localhost:8080/j112/rest-1/companies/list",
dataType: 'json',
dataSrc: "data",
error: function ( xhr, textStatus, error ) {
if ( textStatus === 'timeout' ) {
alert( 'Timout error. The server took too long to send back the data.\nPlease try again.' );
}
else {
alert( 'User Not In Session.' );
location.href = "login.html";
}
myDataTable.fnProcessingIndicator( false );
}//function
}/* ajax: */,
scrollCollapse: true,
bDestroy: true,
serverSide:true,
fnRowCallback : function( nRow, aData, iDisplayIndex, iDisplayIndexFull ) { // this function is called for each row, but I could not use it to add the link
// if ( aData[1] == "A" )
//var td0 = $('td:eq(0)', nRow)[0];
// $('td:eq(0)', nRow).html( 'A');
// $('td:eq(0)', nRow).html( '<b>A</b>' )
},// fnRowCallback
initComplete : function(settings, json) { // this function is called after table is populated
//$("#compListDiv").show(); // this did not work so I used regular js to show the DIV
var d1 = document.getElementById('compListDiv');
d1.style.visibility = 'visible';
}, //initComplete
"columnDefs": [
{ "width": "10%", "targets": 0 },
{ "width": "20%", "targets": 0 },
{ "width": "70%", "targets": 0 }
],
"columns":[
//{"data" : "id"},
{ // render
"data": function (data, type, row, meta) {
return '' + data.id + '';
}
},
{"data" : "name"},
{"data" : "address"}
]
}); // dataTable()
}// companiesList()
