button().disable()
Disable the selected button.
Please note - this property requires the Buttons extension for DataTables.
Description
It can often be useful to enable and disable a button based on some external logic. A common example is an editing button that is disabled when no rows are selected in a table.
When a button is disabled its visual appearance is updated to show its deactivated status (this is done by adding the class disabled
to the button element). Additionally, when a disabled button is clicked on (or otherwise activated by the keyboard or button().trigger()
) the button's action is not executed.
This method can be used to dynamically disable a single button. Unlike its counterpart method, button().enable()
, this method cannot be used to both enable and disable a button, it can only be used to disable.
Type
function buttons).disable()
- Description:
Disable the selected button.

DataTables API instance with the selected button in the result set, available for chaining further operations on the button.
Examples
Disable button index 2-1:
var table = $('#myTable').DataTable();
table.button( '2-1' ).disable();
Set enabled state on a logic condition:
var table = $('#myTable').DataTable();
if ( table.rows( { selected: true } ).indexes().length === 0 ) {
table.button( 'edit:name' ).disable();
}
else {
table.button( 'edit:name' ).enable();
