How to manually update datatables table with new JSON data
SOLUTION: (Notice: this solution is for datatables version 1.10.4 (at the moment) not legacy version).
CLARIFICATION Per the API documentation (1.10.15), the API can be accessed three ways:
-
The modern definition of DataTables (upper camel case):
var datatable = $( selector ).DataTable();
-
The legacy definition of DataTables (lower camel case):
var datatable = $( selector ).dataTable().api();
-
Using the
new
syntax.var datatable = new $.fn.dataTable.Api( selector );
Then load the data like so:
$.get('myUrl', function(newDataArray) {
datatable.clear();
datatable.rows.add(newDataArray);
datatable.draw();
});
Use draw(false)
to stay on the same page after the data update.
API references:
https://datatables.net/reference/api/clear()
https://datatables.net/reference/api/rows.add()
https://datatables.net/reference/api/draw()
You can use:
$('#table').dataTable().fnClearTable();
$('#table').dataTable().fnAddData(myData2);
Jsfiddle
Update. And yes current documentation is not so good but if you are okay using older versions you can refer legacy documentation.
