event.isDefaultPrevented() Method

An event is an action occurred by the user. Therefore, many functions and methods can be set according to those actions performed. When these actions are defined for an event interface, we term those as the event properties. There are various predefined event properties in jQuery. Here, let's discuss the event.isDefaultPrevented() method.

The event.isDefaultPrevented() is a built-in method in jQuery. This method helps us to check whether the event.preventDefault property has been implemented for the selected element or not.

The preventDefault() method allows the element to avoid the execution of the attached event handler.

Hence, the event.IsDefaultPrevented() indirectly checks if the event handler has to be executed or not. It returns the Boolean values – true or false. If the event is prevented, then it returns true, otherwise false.
