event.isPropagationStopped() 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.isPropagationStopped() Method.

The event.isPropagationStopped() is a built-in property in jQuery. This property helps us to check whether the event.stopPropagation property has been called for the selected element or not.

The stopPropagation property allows the element to avoid the execution of the parent event handlers for the specific element. It prevents the bubbling of the events to the parent elements.

Hence, the event.isPropagationStopped() indirectly checks if parent event handlers have to be executed or not. It returns the Boolean values – 'true' or 'false'. If the event propagation is stopped, then it returns 'true', otherwise 'false'.
