接下来，在init方法中添加代码，将鼠标移动处理程序与事件关联起来，然后保存修改。

标签不接受焦点(换句话说，用户不能通过tab键或鼠标移动到标签)，因此，标签无法产生输入事件。
Labels do not receive focus (in other words, a user cannot move to the label with the Tab key or a mouse) and, thus, do not generate input events.
在本文中，我们对应用程序进行了改动，让其只对应于单击事件来检索数据，因此，我们不会因鼠标在其上移动而为此图像拉出数据。

正如上面介绍的一样，编辑器标签有一种默认的拖放行为，它将进行重新排列和平铺操作，这可以使用拖放检测、鼠标移动和鼠标释放类型的事件的监听器实现。
As mentioned, Editor tabs have a default drag-and-drop behavior meant for rearranging and tiling, which is implemented by having listeners for drag-detect, mouse-move, and mouse-up event types.
最可靠的方法是移动鼠标，单击窗口（例如，在GoogleSearch框内）并发送Ctrl+t，确保击键事件由Firefox处理。
Moving the mouse, clicking the window (in the Google Search box, for example), and sending the Ctrl+t is the most reliable method of ensuring that the keystrokes are processed by Firefox.
当鼠标指针刚进入元素边界时，以及鼠标指针仍在元素边界内并且移动时，都会发生此事件。
