How to manually update datatables table with new JSON data

Question

I am using plugin jQuery datatables and load my data which I have loaded in DOM at the bottom of page and initiates plugin in this way:

var myData = [     {         "id": 1,         "first_name": "John",         "last_name": "Doe"     } ];  $('#table').dataTable({     data: myData         columns: [         { data: 'id' },         { data: 'first_name' },         { data: 'last_name' }     ] }); 

Now. after performing some action I want to get new data using ajax (but not ajax option build in datatables - don't get me wrong!) and update the table with these data. How can i do that using datatables API? The documentation is very confusing and I can not find a solution. Any help will be very much appreciated. Thanks.

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:

1. The modern definition of DataTables (upper camel case):

   var datatable = $( selector ).DataTable();

2. The legacy definition of DataTables (lower camel case):

   var datatable = $( selector ).dataTable().api();

3. 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.
