我将通过对代码求值来执行动作；如果代码可能失败，那么我将会捕获那个错误。

I'll run that action by evaluating the code; if the code should fail, then I will catch that error.

无论使用冒泡阶段还是捕获阶段，默认动作总是在所有的传播完成后执行。

Whether the bubbling or capture phase is used, the default action always happens after all event propagation is finished.

例如，设备代理可能会在捕获或接收数据时发布事件消息，指示已经触发了动作传感器或已经读取了RFID标签。

For example, a device agent might publish an event message whenever it captures or receives data indicating a motion sensor has been triggered or that an RFID tag has been read.
