Processing an input event within an application

摘要

Processing an input event within an application includes detecting an input event within an application executing on a first thread, the input event being associated with an event handler. A separate execution corresponding to a current state of the application is performed on a second thread based on the event handler associated with the input event. Within the separate execution, a determination is made whether the event handler modifies at least one of a document associated with the application or a default behavior of the application. In a case where the event handler does not modify at least one of the document or the behavior, the subject technology refrains from invoking the event handler on the first thread.

1. A system for processing an input event within an application, the system comprising:
one or more processors; and a machine-readable medium comprising instructions stored therein, which when executed by the processors, cause the processors to perform operations comprising:
detecting an input event within an application executing on a first thread, the input event being associated with an event handler;performing a separate execution corresponding to a current state of the application on a second thread based on the event handler associated with the input event;determining, within the separate execution, whether the event handler modifies at least one of a document associated with the application or a default behavior of the application; andrefraining, in a case where the event handler does not modify at least one of the document or the default behavior, from invoking the event handler on the first thread.
