问题
My table is not populating. I can see that it is getting the correct JSON
JSON Data received looks like this:
[
{
"id": "1",
"name": "FooBar",
"predicted": "0",
"points": "1",
"section_id": "1",
"detail_alias": ""
...
},
...
]
HTML
<table id="example"></table>
JS
$('#example').dataTable( {
"ajaxSource": "rest/index.php?m=foo",
"columns": [
{ "data": "id" },
{ "data": "name" },
{ "data": "detail_alias" },
{ "data": "points" }
]
} );
All I'm seeing in my browser is:
It says "Loading..." when the network tab shows that the call had a 200 response with the correct data.
Why isn't the table populating?
回答1:
So the ajaxSource in my question was expecting data to be formatted as such:
{ data: [ { ...
And I didn't want to have to modify my back end to send data in this format as it would cause problems in other places. I'm assuming other people that end up on this page looking for a solution will likely have the same issue.
My solution was to get the data via jQuery.ajax() and then pass it in to the aaData field, like this:
$.ajax({
'url': "/rest/index.php?m=foo",
'method': "GET",
'contentType': 'application/json'
}).done( function(data) {
$('#example').dataTable( {
"aaData": data,
"columns": [
{ "data": "id" },
{ "data": "name" },
{ "data": "detail_alias" },
{ "data": "points" }
]
})
})
This allows me to not have to worry about changing the json data from the format in the question.
I like this way better anyway as I feel it gives me more flexibility if I wanted to do modify or use the data for anything else at the same time.

I think you must return your json with the array of "aaData"
return dataTabledata['aaData'] = 'your json data'
By default DataTables will use the "aaData" property of the returned data which is an array of arrays with one entry for each column in the table.
In your jQuery create ajax that will handle the data from your server side
function getdtData(){
/*clear table row first*/
$('#sample').dataTable().fnDestroy();
/*populate your datatable using ajax*/
$('#sample').dataTable({
"sDom": 'frtip',
"bServerSide": true,
/*server side source*/
"sAjaxSource": "rest/index.php?m=foo",
/* we use sDom to specify the lenght of the pagination if you will using pagination in your data table*/
"lengthMenu": [[ 5, 5], [ 5, 5]],
"aoColumnDefs": [
{ "aTargets": [ 0 ], "bSortable": false},
{ "aTargets": [ 1 ], "bSortable": false },
{ "aTargets": [ 2 ], "bSortable": false },
{ "aTargets": [ 3 ], "bSortable": false }
]
});
refer to this documentation http://legacy.datatables.net/usage/server-side
回答3:
The table is not populating because you have no data object in your received JSON data but referencing it (data object) for display in the table columns.
Based on your dataTable initialisation, your JSON data should look like this:
{"data":[
{
"id": "1",
"name": "FooBar",
"predicted": "0",
"points": "1",
"section_id": "1",
"detail_alias": ""
...
},
...
]}

Had the same problem while using codeigniter json_encode tipe of data, it returned a Flat array data source afther a few days of trying
"aaData": data,
i finaly got it working using
"ajax": { "url": "index.php/controller/function", "dataSrc": "" },
instead of
"data": [ [ "Tiger Nixon", "System Architect", "Edinburgh", "5421", "2011/04/25", "$320,800" ],
, in reality it is quite simple see datatble ajax documentation
$(document).ready(function() {
$('#t1').DataTable( {
"ajax": {
"url": "<?php echo base_url(); ?>index.php/controller/function",
"dataSrc": ""
},
"columns": [
{ "data": "CCODIGOCLIENTE" },
{ "data": "CRAZONSOCIAL" },
{ "data": "PENDIENTE" },
{ "data": "siete" },
{ "data": "sietev" },
{ "data": "catorcev" },
{ "data": "catorce" },
{ "data": "veintiunov" },
{ "data": "veintiuno" },
{ "data": "mes" },
{ "data": "bimestre" },
{ "data": "trimestre" }
]
} );
} );<link href="https://cdn.datatables.net/1.10.19/css/jquery.dataTables.min.css" rel="stylesheet"/>
<script src="https://cdn.datatables.net/1.10.19/js/jquery.dataTables.min.js"></script>

<table id="t1" class="display" style="width:100%">
<thead>
<tr>

</table>
a few pointers for begginers...
- make sure your script is below you libraries
- that the number of columns matches your data
- make your datatable id unique
good luck yaall
