Editor events

Attention! We strongly recommend first to learn more about Sites module REST documentation to understand how the module functions (with REST available in Bitrix24 Self-hosted editions). View this documentation as useful source when working with Bitrix24 Self-hosted editions and find out more details about API and only REST is not enough.

The editor can register several event handlers. It allows you to find solution for various tasks. In some cases, such handlers are essential. For example, block with a slider, where each slider - is separate details card. When the number of cards is changed, most likely the slider code must be re-initiated (depending on specific libraries).
