Propagation means bubbling up to parent elements or capturing down to child elements.

Note: As of v17, e.persist() doesn't do anything because the SyntheticEvent is no longer pooled. Note: As of v0.14, returning false from an event handler will no longer stop event propagation. Instead, e.stopPropagation() or e.preventDefault() should be triggered manually, as appropriate. Supported Events . React normalizes events so that they have consistent properties across different ... Event propagation in a nutshell. Event propagation is a way to describe the "stack" of events that are fired in a web browser. In our table example above, clicking on the a tag is the first event that we will fire, but there are other events too.

HTML DOM stopPropagation () Event Method: The stopPropagation () method is used to stop propagation of event calling i.e. the parent event is called we can stop the propagation of calling its children by using the stopPropagation () method and vice-versa. Question: How do I cancel event bubbling or stop event propagation? Answer: Sometimes, event bubbling may have unintended consequences. For example, in the event bubbling demo clicking the Reset button triggers not only the button's own event handler function resetTable(), but also another, higher-level onclick event handler, which has the unintended consequence of colorizing the entire page. However, generally speaking you should be avoiding inline event handlers if you need to to anything complicated like stopping propagation. Writing your event handlers separately and the attaching them to elements is a much better idea in the medium and long term, both for readability and maintainability.

The stopImmediatePropagation () method of the Event interface prevents other listeners of the same event from being called.
