    • A method and computing device are provided for processing user events received via a user interface, such as a touchscreen, in multiple threads. When a user event is received for a target element in a webpage, the user event is dispatched to both a main browser thread and a secondary thread. The secondary thread processes user events in accordance with established default actions defined within the browser, while the main thread processes the user events in accordance with any event handlers defined for that target element. The main thread processing may be delayed by other interleaved task, and the secondary thread may be given priority over the main thread. When the secondary thread completes processing, an updated webpage is displayed. When the main thread subsequently completes processing, its updated rendering of the webpage is displayed. The secondary thread thus provides an early user interface response to the user event.
    • 提供了一种方法和计算装置,用于处理经由诸如触摸屏的用户界面在多个线程中接收的用户事件。 当为网页中的目标元素接收到用户事件时,将将用户事件分派到主浏览器线程和辅助线程。 次要线程根据在浏览器中定义的已建立的默认动作来处理用户事件,而主线程根据为该目标元素定义的任何事件处理程序处理用户事件。 主线程处理可能被其他交错任务延迟,次级线程可能优先于主线程。 辅助线程完成处理后,将显示更新的网页。 当主线程随后完成处理时,显示其更新的网页呈现。 次级线程因此提供对用户事件的早期用户界面响应。
