This summer vacation, I took part in the "Social Practice Activities for College Students to Go to the Countryside in Summer" organized by the School of Urban Management of Hunan City University. In order to let students better master professional knowledge, Carry forward patriotic enthusiasm, serve the society and the people attentively, let students have all-round contact, understand the situation of poor areas in society and personality, and through investigation, find out the actual problems existing in the area, analyze and make solutions, and experience and comprehend from them to enhance the sense of mission of college students. In order to cultivate good social adaptation potential and strive to train oneself to become a contemporary college student who is beneficial to the society and the people, Secretary Liu Hui, Secretary of the General Party Branch of the Institute of Urban Management, was arranged to be our leading teacher. Under the form of building a new socialist countryside in the whole country, the theme of our activity is "serving the new countryside and building a new home.""I think so, But it was too late, I'm sitting here and I'm telling you, It is said in a straight-forward way, But when this happened, Basically between crackles, The company commander's military quality is so strong, Also see in the eye can't help, He saw that the three men could not be saved, I think he is also in a hurry, From behind, he grabbed a three-piece explosive cartridge, Unscrewed the back cover, pulled the lead and held it on his shoulder, just like the javelin thrower in the Olympics. He threw the cartridge sideways, He threw such a heavy thing so far away, It's almost farther than I threw a grenade, Because I don't know how many times the front of the position has been ploughed by artillery, Full of floating soil, It's very soft, So when the explosive cylinder landed, it was finally inserted obliquely on the ground. It was also impartially inserted in the most densely populated position of the group of strange dogs, Then the explosive barrel exploded, which was quite powerful. I felt that it was more powerful than a shell. The width of the whole position was completely covered by 10 meters in front of it. On the spot, the strange dogs that were still biting the body and rushing halfway were all killed. My military cap was blown off by the shock wave. "Wang Zeduan said....Today's problem mainly involves several: objects, triggering events, capturing events, executing processing, and blistering. 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.It is not possible to stack multiple penalty layers with multiple skills at the same time. Penalties have built-in CD, although I am not sure how the penalty stack works when scourge + dedication + main skills are output together.EventHandler is a delegate
