Element.dispatchEvent介绍

[英]Dispatched the given event with this element as its target. The event will go through all phases of the browser's normal event dispatch mechanism. Note: Because the browser's normal dispatch mechanism is used, exceptions thrown from within handlers triggered by this method cannot be caught by wrapping this method in a try/catch block. Such exceptions will be caught by the com.google.gwt.core.client.GWT#setUncaughtExceptionHandler(com.google.gwt.core.client.GWT.UncaughtExceptionHandler)as usual.
[中]已将此元素作为其目标调度给定事件。事件将经历浏览器正常事件分派机制的所有阶段。注意：由于使用浏览器的正常分派机制，因此无法通过将此方法包装在try/catch块中来捕获从此方法触发的处理程序中引发的异常。此类异常将被com捕获。谷歌。gwt。果心客户GWT#setUncaughtExceptionHandler（com.google.GWT.core.client.GWT.UncaughtExceptionHandler）与往常一样。
