4. The switching relationship between states is just piling up if and else statements in the buttonWasPressed method. Adding or modifying a state may require changing several operations, which makes buttonWasPressed more difficult to read and maintain.
The propagation of events is directed. When a button is clicked, the event generated starts to propagate upward from the button (just like a blister comes up from the bottom of a cup, which is why it is called event bubbling), but this event always looks for whether a specific attribute has a value. For example, the click event of a button first looks for a meaningful definition of whether there is an onclick attribute on the button (i.e. The attribute points to an existing function or an executable statement), and if so, executes the function or statement; The event then continues to propagate up to the upper layer object of the button (for example, a form object or document object, which in short contains the parent object of the button). If the object also defines the onclick attribute, the value of the attribute is executed.

I have also seen it spray on cars. The fuel burns to extinguish the flame for more than five minutes. When it finally went out, the whole car head was burned by more than half. Although I don't know the specific figure of the temperature, the comrades in the chemical defense class said it was at least 1300-1500 degrees Celsius, so I thought at that time, even the steel plate could melt into the flame of molten iron in a few minutes. It was not a piece of cake to burn this insect. Even if you are much bigger than the average wasp, may there be steel plates that are resistant to burning? After being ignited by the flame, it should be burned to ashes in an instant. But the result was not what I thought. After being ignited, the big wasp was quite resistant to burning. Actually flying around in the air for more than ten seconds before being burned, the air disintegrated and died. But this has become a good thing, It is precisely because it will burn to death for a while. So flying in the air with flames all over it must be either because of the sharp pain, Either they lost their direction because of something else, Anyway, it is flying around in the air, As a result, they hit many of their peers in the process of flying around. Then it ignited the same kind that was hit, If the ignited kind bumps into each other again, To ignite another kind, It just went through a couple of cycles, Most of the big wasps were set on fire, That will burn quickly. The sky is full of the sound of "crackling" burning meat, and there is a smell of barbecue burnt. The black corpses of wasps that have been burned apart and fallen and the corpses of wasps that have been smashed by bullets are piled up most. One foot is thick enough to reach the knee. That scene, I
