rowInvalidate

Since: DataTables 3.0

Triggered when the data in a row is updated.

Description

It can be useful to know if the data in a row has been updated. You might wish to know this if some other component needs to be updated, or events changed. This event provides exactly that ability.

Type

`function( e, settings, rowIndex, colIndex )`

Parameters:

	Name	Type	Optional
1	`e`	`object`	No
	Event object
2	`settings`	`DataTable.Context`	No
	DataTables settings object
3	`rowIndex`	`number`	No
	The data index for the row that was updated (for use with `row()`).
4	`colIndex`	`number`, `undefined`	No
	Column index, if it was the data in a specific column that was updated (e.g. using `cell().data()`). Will be undefined if a general row data update.

Example

Record a message whenever data in a row is updated:

let table = new DataTable('#myTable');

table.on('rowInvalidate', function (e, settings, rowIndex) {
	console.log('Row data updated for row index', rowIndex);
});

table.cell(0, 0).data('My new data').draw();
