Compared with the online work class, the online work class mode company was established relatively early and has a relatively rich variety of courses. Thanks to the long development time, its curriculum has been continuously polished and matured in market feedback. In addition, its company's positioning has been continuously adjusted according to market demand, forming a relatively accurate positioning, with relatively wide product coverage and more specific details. However, there is a new trend that is worth noting. At present, most offline thinking ability training institutions have also begun to think about online development to effectively supplement offline education.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.I nodded at this passage, Understand that what Zhang Xiaobo said is indeed reasonable, It is not a lie, Here I think it is necessary to give you one thing about popular science. So we have to say something digressive: The result of a real bullet hitting a petrol tank is not the same as that shown in most movies. One shot can explode the petrol tank, But this is not the case, Although a pure metal projectile will rub against the air at a speed of hundreds of meters per second to generate equivalent heat, And will produce sparks after hitting the metal oil drum, But none of this is enough to ignite petrol, Especially for gasoline with a large total amount, to ignite gasoline, please remember one thing-open flame must be used. In addition, gasoline is a flammable item, but it is not an explosive item in the true sense. Only after reaching a certain total amount can explosion be caused. If the total amount is insufficient, it can only cause combustion without explosion.小莉（林心如饰）是D吧里的狂野女鼓手，与女同事情同手足。为了帮女同事偿还高利贷，夜里不幸被街市小混混砍伤昏迷街头。达开（黄维德饰）在街上路过，偶遇受伤的小莉并送他回家包扎好便离去。一面之缘却令达开爱上了小莉。 几日过后达开去酒吧遇到正与人争执的小净（林心如饰），并从中调解，遭到对方一阵拳脚。小净感激之余对达开也颇生好感，但达开却以为小净就是上次自己所救的那个女孩小莉。并向她表白，小净莫名其妙，但心底煞是喜悦，另一方面小蓝（吴辰君饰）和付振云（黄少祺饰）两个生命中相识的恋人几度相逢又别离的人生。 作为知性、事业心重的上班族，戏里和初恋情人黄少祺有许多学生时期的美好回忆。影片中错踪复杂的感情，三起三落的人生。让人即回味又深思…五人的关系就像现代男女，在黑夜与白天的错身当中，感情有了不同的邂逅与相遇… 渴望单纯爱情的加嘉（柳岩饰）不顾危险，跟未婚夫宏泰东渡日本。来到宏泰家在富士山下的经营的赤石温泉。刚刚安顿下来加嘉就发现未婚夫一家和周围的居民不但行为诡异，还对她充满了敌意。前朝公主司徒静被大将军司徒青云夫妇收养，倍受宠爱。静小姐天性活泼开朗、冰雪聪明。她美丽善良，还生就一副侠义心肠。虽是红妆女儿，深宅大院却锁不住她。她最喜欢外面的自由世界，每每扮成男子，游走于市井小巷中，在平民百姓间混得酣畅淋漓。静公主善良无比，时常济弱扶困。加上她以龙少侠自居，我行我素，天马行空，又喜恶作剧，所以三教九流的朋友送她亲昵绰号“小龙虾”。
