JavaScript Selection - beforeSelect Event

fires on selecting an item, but before the item is really selected

beforeSelect: (id: string | number) => void | boolean;

• id: string | number - the id of an item

Return false to prevent selecting of an item; otherwise, true.

Example

component.selection.events.on("beforeSelect", function(id) {
    console.log(id);
    return false;
});

Starting from v7.0, you can also apply the simplified version of the event:

component.events.on("beforeSelect", function(id) {
    console.log(id);
    return false;
});
