eventtargetresult

Eventtargetresult is not a standard web API term but a naming convention used in some codebases to describe a data container that collects the outcomes produced by listeners attached to an EventTarget when an event is dispatched. It is used to summarize or examine the results of multiple listeners, rather than relying on a single return value from a dispatch operation.

A typical event target system involves an object that can have zero or more listeners registered for various event types. An EventTargetResult, when present, acts as a wrapper or aggregator that records information about each listener’s response. Common fields in such a pattern may include the target itself, the event object, a collection of results from listeners, and flags indicating whether the event was handled or whether propagation or the default action was canceled.

Usage of an EventTargetResult pattern is mainly in library design or application code that needs more visibility into listener outcomes. It supports use cases such as collecting all listener responses for analysis, short-circuiting further listener invocation based on a particular result, or determining a final outcome based on multiple independent opinions. Depending on the implementation, it may provide methods to add results, query whether any listener handled the event, or retrieve the first or all results.

In standards terms, the DOM and common web APIs do not define a built-in EventTargetResult type. When encountered, it is typically a project-specific data structure or a utility class used to manage and inspect the results of an event dispatch.
