Cannot reinitialise DataTable - dynamic data for datatable

In the current version of DataTables (1.10.4) you can simply add destroy:true to the configuration to make sure any table already present is removed before being re-initialised.

$('#example').dataTable({
    destroy: true,
    aaData: response.data
});

This helped me:

var table = $('#example').DataTable( {
    // Clear previous data
    destroy: true,
    // Load new data with AJAX from data.json file.
    ajax: "data.json" 
} );

This tech note section from datatables explains the reason for this warning. Relevant information from there:

This error is triggered by passing in options to a DataTables constructor object when the DataTable instance for the selected node has already been initialised. For example:

$('#example').dataTable( {
    paging: false
} );


$('#example').dataTable( {
    searching: false
} );

The above documentation explains two ways to deal with this.

  1. Retrieve: It explains how to apply additional options after the initialization (works even if it is not initialized before) by using setting retrieve to true as follows:
table = $('#example').DataTable( {
    retrieve: true,
    paging: false
} );
  1. Destroy: In this case you can destroy the object explicitly by calling table.destroy(); and then creating the table again. Or you can simply pass destroy: true option as mentioned in the accepted answer.

    table = $('#example').DataTable( {
        paging: false
    } );
    
    table.destroy();
    
    table = $('#example').DataTable( {
        searching: false
    } );
    

Using destroy:true option:

$('#example').DataTable( {
    destroy: true,
    searching: false } );

Note: This error may also occur if you include your javascript file that creates the dataTable multiple times. I was using apache tiles and included it in base as well as extended definition which also resulted in this error.


Try something like below

    var $table=$('#example').dataTable({
                    "aaData": response.data,
                });


    $table.fnDestroy();
