This is actually the whole process of JS execution. The process of bubbling is very interesting. In fact, it is like a glass of water, but this glass of water is hierarchical, and the bottom is the object of the current trigger event. Then the higher the range, the larger the range. The top layer must be window and the penultimate layer must be document. In the process of floating up, the bubble will judge whether the layer currently reached has a binding event handling method. If there is any, the corresponding processing is executed. If not, it will continue to blister. Until you reach the top window window layer. We can do corresponding processing at any layer to prevent the event from continuing to bubble. The method is the method that calls the event object to prevent blistering. Event.stopPropagation (); The following is a process method written to verify JS event blistering.　　最终公主与自己的小分队通过了宝库世界的重重危险，阿里巴巴实现了打败强盗的愿望。公主得到了王者之心，也明白了成为国王最需要的能力，在冒险中成长成熟起来。 ©豆瓣1Elf=ELF ('001')
