event.preventDefault()


event.preventDefault()Returns: undefined

Description: If this method is called, the default action of the event will not be triggered.

For example, clicked anchors will not take the browser to a new URL. We can use event.isDefaultPrevented() to determine if this method has been called by an event handler that was triggered by this event.

Example:

Cancel the default action (navigation) of the click.
