Introducing select-deselect event handlers for DataTable

Introduction

DataTable is a powerful jQuery plugin that provides advanced interaction controls to HTML tables. One of its key features is the ability to select and deselect rows using built-in methods and events. In this article, we will introduce select-deselect event handlers for DataTable, which enhance its functionality and give developers more control over selecting and deselecting rows.

What are Select-Deselect Event Handlers?

Select-deselect event handlers are custom events that are triggered when rows are selected or deselected in a DataTable. These events give developers the ability to define their own logic for handling row selections and deselections, which can be useful for implementing custom behavior based on the selected rows.

Using Select-Deselect Event Handlers

To use select-deselect event handlers in a DataTable, you will first need to create a custom event handler function. This function will be called whenever a row is selected or deselected in the DataTable. The function should take two parameters: the event object and an array of the selected row data.

function myCustomHandler(event, selectedRowsData) {
  // Your custom logic for handling row selections
}

Once you have created your custom event handler function, you can set it as the value of the 'select' or 'deselect' event properties in the DataTable initialization object.

$('#myTable').DataTable({
  select: {
    style: 'multi',
    selector: 'td:first-child',
    info: false,
    event: 'custom-select'
  },
  deselect: {
    event: 'custom-deselect'
  }
});

$('#myTable').on('custom-select custom-deselect', myCustomHandler);

In the example above, we have set the 'select' and 'deselect' events to trigger custom events named 'custom-select' and 'custom-deselect', respectively. We have also attached our custom event handler function 'myCustomHandler' to these events using the jQuery 'on' method.

Conclusion

Select-deselect event handlers are a powerful feature that can greatly enhance the functionality of DataTables. By using these custom events, developers can create their own logic for handling row selections and deselections, which can be very useful in implementing custom behavior based on the selected rows.
