Stop the default browser actions - Basic JavaScript Fast (62) | preventDefault, isDefaultPrevented

Published: 28 January 2024
on channel: Begin Coding Fast

The video discusses the ways to stop the default browser actions using JavaScript. There are two ways to do so. The first way is to use "return false" on the event handler placed on the HTML file. The second way is to use the preventDefault function on an event object. If the preventDefault function is applied to an event object, the isDefaultPrevented property of the event object becomes true. Bubbling effect still applies, so that once the descendant has prevented the default browser actions, the ancestors cannot do the actions that would have done initially due to bubbling.
