只读alt只读AT_只读bubblesReturns true or false depending on how event was initialized. True if event goes through its target's ancestors in reverse tree order, and false otherwise.
只读BUBBLING_只读button只读buttons只读cancelableReturns true or false depending on how event was initialized. Its return value does not always carry meaning, but true can indicate that part of the operation during which event was dispatched, can be canceled by invoking the preventDefault() method.
只读CAPTURING_只读clientX只读clientY只读composedReturns true or false depending on how event was initialized. True if event invokes listeners past a ShadowRoot node that is the root of its target, and false otherwise.
只读ctrl只读currentReturns the object whose event listener's callback is currently being invoked.
只读defaultReturns true if preventDefault() was invoked successfully to indicate cancelation, and false otherwise.
只读detail只读eventReturns the event's phase, which is one of NONE, CAPTURING_PHASE, AT_TARGET, and BUBBLING_PHASE.

只读view只读which只读width只读x只读yReturns the invocation target objects of event's path (objects on which listeners will be invoked), except for any nodes in shadow trees of which the shadow root's mode is "closed" that are not reachable from event's currentTarget.
Available only in secure contexts.
The state of a DOM event produced by a pointer such as the geometry of the contact point, the device type that generated the event, the amount of pressure that was applied on the contact surface, etc.
