Format data returned from JSON in DataTable [duplicate]

This question already has answers here:
use of comma and datatable decimals
(2 answers)
Closed 7 months ago.
I am reading a json file from remote url and displaying it in DataTable.
<script>
$(document).ready(function () {
$('#example').DataTable(
{
ajax: {
method: 'GET',
url: 'https://chainformed.s3.us-east-1.amazonaws.com/Data/mostwatched.json',
dataSrc: ''
},
paging: false,
responsive: true,
language: {
url: "//cdn.datatables.net/plug-ins/1.12.1/i18n/tr.json",
},
columns: [
{ "data": "id" },
{ "data": "rank" },
{ "data": "name" },
{ "data": "watchlist" },
{ "data": "percentage" },
{ "data": "difference" },
{ "data": "timestamp" }
]
});
$('.dataTables_length').addClass('bs-select');
});
</script>
I would like to be able to format and manipulate the data returned from that json file. What is the best way to do it?
For example, i would like to change the values from ({ "data": "watchlist" }) field to number format with comma. How can i achieve it?
I tried this but with no luck: https://datatables.net/reference/option/ajax.dataSrc

Use render element.
Read document from Format output data - orthogonal data
and example
Another way u can use columnDefs
<script>
$(document).ready(function () {
$('#example').DataTable(
{
ajax: {
method: 'GET',
url: 'https://chainformed.s3.us-east-1.amazonaws.com/Data/mostwatched.json',
dataSrc: ''
},
paging: false,
responsive: true,
language: {
url: "//cdn.datatables.net/plug-ins/1.12.1/i18n/tr.json",
},
columns: [
{ "data": "id" },
{ "data": "rank" },
{ "data": "name" },
{ "data": "watchlist" },
{ "data": "percentage" },
{ "data": "difference" },
{ "data": "timestamp" }
],
'columnDefs': [
{
"targets": 3,
"data": "watchlist",
"render": function ( data, type, row, meta ) {
return data.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
}
}
]
});
$('.dataTables_length').addClass('bs-select');
});

Ordering columns in JQuery DataTable -- when data is fed through Javascript

There are some forum questions similar to what I'm trying to do but I haven't been able to make it work.
We are pulling data into a DataTable through javascript. I'd like to set the data-order using a different column.
However, when I try the column is being interpreted as a string and not integer.
Here is what makes the table:
var securityTable = $('#security-table').DataTable({
"data": securitydata.guards,
"columns": [
{
"className": 'details-control',
"data": null,
"orderable": false,
//creates square for details row
"render": function (d) {
return '<i class="fa fa-plus-square" aria-hidden="true"></span>';
},
"defaultContent": ''
},
// is sorting by "sort" but is seeing numbers as alphebetical not numeric
{ "data": {
_: "date.display",
sort: "date.date_order"
} },
{ "data": "place" },
{ "data": {
_: "shot.display",
sort: "shot.shot_order"
} },
],
"paging": false,
"searching": false
});
This is what the data looks like:
var securitydata = {
"guards": [
{
"date": {
"display": "April 15, 2011",
"date_order": 1
},
"reported": "Yes",
"place": "Chicago, auto parts yard",
"shot": {
"display": "No one hit",
"shot_order": 24
},
"blurb": "A 52-year-old guard at an auto parts lot shot at a vehicle he said was coming toward him. The man inside the vehicle, accused of stealing equipment from the lot, drove away and was not reported injured.",
"link": ""
},
This is what we were using for help

Using the same example, but with sorthing
$(document).ready(function() {
$('#example').DataTable( {
order: [[ 2, "desc" ]],
ajax: "data/orthogonal.txt",
columns: [
{ data: "name" },
{ data: "position" },
{ data: "office" },
{ data: "extn" },
{ data: {
_: "start_date.display",
sort: "start_date.timestamp"
} },
{ data: "salary" }
]
} );
} );

How to load Datatables from JSON object directly on Ajax success result?

After long time searching here around I can't find a solution to this problem, loading Datatables via Ajax GET is well documented but how can I use directly a JSON response after an Ajax POST?
This is my PHP function:
function getRelated() {
var elements = (document.getElementsByClassName('exashare'));
var query = [];
for(var i=0;typeof(elements[i])!='undefined';query.push(elements[i++].getAttribute('data-id')));
query = query.join(',');
$.ajax({
type: "POST",
url: baseUrl+"/requests/get_related.php",
data: "query="+query+'&_token='+_token,
cache: false,
success: function(html){
$('#example').DataTable( {
"processing": true,
"serverSide": true,
"ajax": {
'url':jQuery.parseJSON(html),
"dataSrc": ""
},
"columns" : [
{ "data": "#" },
{ "data": "id" },
{ "data": "art" },
{ "data": "name" },
{ "data": "title" },
{ "data": "tag" },
{ "data": "likes" },
{ "data": "views" },
{ "data": "duration" },
{ "data": "time" }
]
});
}
});
}
The JSON on success looks like this:
{
"data": [{
"#": "1",
"id": "9",
"art": "default\/def8.jpg",
"name": "Simon The Cat",
"title": "Riflessioni sulla vita",
"tag": "riflessioni,vita,",
"likes": "1",
"views": "1024",
"duration": "185",
"time": "2015-11-30 19:36:31"
}, {
"#": "2",
"id": "15",
"art": "default\/def2.jpg",
"name": "Simon The Cat",
"title": "Riflessioni sulla morte",
"tag": "riflessioni,morte,",
"likes": "1",
"views": "1003",
"duration": "185",
"time": "2015-11-14 12:06:21"
},
...]
}
I also tried this:
//from this:
$('#example').DataTable( {
"processing": true,
"serverSide": true,
"ajax": {
'url':jQuery.parseJSON(html),
"dataSrc": ""
},
...
//to this:
$('#example').DataTable( {
"ajax": jQuery.parseJSON(html),
...
But on console it always shows me the error "lenght of undefined".
I already tried to load data directly from a JSON file url
containing the same response here above and it works well.
How can I load JSON data on Ajax POST success results to populate my table?

Finally, after many tries, I found the solution that works with the latest Datatables release (1.10.13):
function getRelated() {
var elements = (document.getElementsByClassName('exashare'));
var query = [];
for(var i=0;typeof(elements[i])!='undefined';query.push(elements[i++].getAttribute('data-id')));
//parse as string
query = query.join(',');
$.ajax({
type: "POST",
url: baseUrl+"/requests/get_related.php",
data: "query="+query+'&_token='+_token,
cache: false,
success: function(html){
//html is a json_encode array so we need to parse it before using
var result = jQuery.parseJSON(html);
$('#example_ert').DataTable( {
//here is the solution
"data": result.data,
"ajax": {
"url": result,
"dataSrc": ""
},
"columns" : [
{ "data": "#" },
{ "data": "id" },
{ "data": "art" },
{ "data": "name" },
{ "data": "title" },
{ "data": "tag" },
{ "data": "likes" },
{ "data": "views" },
{ "data": "duration" },
{ "data": "time" }
]
});
}
});
}

How to Pass geojson array to datatable dyanamically using javascript

I want to pass one geojson file to dynamically created datatable using javascript,I am unable to identify column names in file..
I have tried this..
CODE
<body>
<table id="example" class="display" cellspacing="0" width="100%">
<thead>
<tr>
<th>fC.type</th>
<th>f.type</th>
<th>f.prop</th>
<th>f.geom.type</th>
<th>geometry.coordinates.0</th>
<th>geometry.coordinates.1</th>
</tr>
</thead>
</table>
</body>
$(document).ready(function () {
$('#example').dataTable({
"ajax": "data/json_file.json",
"processing": true,
"columns": [
{ "mData": "type" },
{ "mData": "features.type" },
{ "mData": "features.properties" },
{ "mData": "geometry.type" },
{ "mData": "geometry.coordinates.0" },
{ "mData": "geometry.coordinates.1" }
]
});
});
geojson File
{
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"properties": {},
"geometry": {
"type": "LineString",
"coordinates": [
[
40.078125,
57.136239319177434
],
[
91.7578125,
58.99531118795094
]
]
}
}
]
}
My output is as shown in image

The problem is actually the datafile, which is valid JSON but not the structure that datatable requires.
Solution 1 : Change the file to expected structure.
{
"data": [
{
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"properties": {},
"geometry": {
"type": "LineString",
"coordinates": [
[
40.078125,
57.136239319177434
],
[
91.7578125,
58.99531118795094
]
]
}
}
]
}
]
}
Solution 2 : Use the dataSrc through which you can modify the ajax response before datatable uses it.
$('#example').dataTable({
"ajax":
{
"url": "json1.json",
"dataSrc": function (json) {
var obj = [];
obj.data = [];
obj.data[0] = json;
return obj.data;
},
},
"processing": "true",
"columns": [
{ "data": "type" },
{ "data": "features.0.type" },
{ "data": "features.0.properties" },
{ "data": "features.0.geometry.type" },
{ "data": "features.0.geometry.coordinates.0" },
{ "data": "features.0.geometry.coordinates.1" }
]
});
Here what I've done is created a new object obj.
Working fiddle here : https://jsfiddle.net/ourqh9ts/

The problem might be that the GeoJSON is not an array but an object.
Try changing your column definitions with these:
"columns": [
{ "data": "type" },
{ "data": "features.0.type" },
{ "data": "features.0.properties" },
{ "data": "features.0.geometry.type" },
{ "data": "features.0.geometry.coordinates.0" },
{ "data": "features.0.geometry.coordinates.1" }
]
