How To Destroy A Datatable?

I'm using datatables and using bootstrap-daterangepicker to select a range for which data will be shown in Datatables. It is working fine. The problem is when I select a new range

Solution 1:

To completely delete and remove the datatable object with its DOM elements you need to :

//Delete the datable object firstif(oTable != null)oTable.fnDestroy();
//Remove all the DOM elements
$('#feedback-datatable').empty();

Solution 2:

Just add this parameter to your declaration:

"bDestroy" : true,

Then whenever you want to "recreate" the table it won't drop an error

P.S. You can create a function to get the required parameters and then reinitialize the table with different options at runtime.

For example I use this one in my programs, if it helps you can adapt it to your needs

 initDataTable($('#tbl1'), 2, 'asc', false, false, 25, false, false, false, 'landscape', rptHdr);  /* Initialize Table */

/*---------------------- Datatable initialization  --------------------------- */
/*
 * @$table           Table id which be initialized
 * @sortCol          Column number that will be initially sortered 
 * @sorOrder         Ascendant (asc) or Descendant (desc)
 * @enFilter         Boolean value to enable or not the filter option
 * @enPaginate       Boolean value to enable or not the filter option
 * @dplyLength       Number of records contained per page when pagination is enabled
 * @enInfo           Boolean value to show or not the records info
 * @autoWidth        Boolean value to enable or not table autowidth
 * @enTblTools       Boolean value to enable or not the table tools addin
 * @pdfOrientation   Page orientation (landscape, portrait) for pdf documents (required enTblTools == enabled)
 * @fileName         Output file naming (required enTblTools == enabled)

Solution 3:

I know this is an old question, but since I bumped into a similar issue and resolved it.

The following should do the trick (the comments are coming from the DataTable API doc).

// Quickly and simply clear a table
$('#feedback-datatable').dataTable().fnClearTable();

// Restore the table to it's original state in the DOM by removing all of DataTables enhancements, alterations to the DOM structure of the table and event listeners
$('#feedback-datatable').dataTable().fnDestroy();

Solution 4:

For DataTables 1.10, the calls are:

// Destroy dataTable
$('#feedback-datatable').DataTable.destroy();

// Remove DOM elements
$('#feedback-datatable').empty();

Solution 5:

For the google searchers

Very hardly I managed to destroy the Datatable, Empty it's all previous data before loading new data and re-initializing Datatable by doing like this,

if ($.fn.DataTable.isDataTable("#myTbl")) {
      ("#myTbl").DataTable().destroy();
}
$('#myTbl tbody > tr').remove();

...

// Load table with new data and re-initialize Datatable
