Approach: To handle DataTable specific events dt namespace is used. All the events are triggered with the dt namespace. The datatable on() method is used which automatically appends dt namespace. Order event is automatically fired when the data in the table is ordered. Paging event is fired whenever pagination feature is used.
HTML table is designed with student’s data with id, name , age, gender and marks as their fields. HTML div with id’s orderResultID and pagingResultID is created to show a message whenever the order and paging events are fired.
Example: The following example code demonstrates how to handle functions whenever the DataTable specific events are fired. A simple message is shown below the table. The developer can write functions according to the application’s need.
