The first scheme is to use the general coding method to realize the preloading technology of the picture. First, create the imgNode element, Then when the method myImage.setSrc is called, a preloaded picture is given to the picture first, and when the picture is loaded, the img element is assigned a value. The second scheme is implemented by using proxy mode. MyImage function is only responsible for creating img elements, proxy function ProxyImage is responsible for setting loading pictures for the picture, and when the picture is really loaded, myImage.setSrc method in myImage is called to set the path of the picture. The advantages and disadvantages between them are as follows:In the system, how do we need to reuse an object, if we repeatedly use the new operator to create the object at this time, it is a great waste of system resources. Since we use the same object every time, why can't we share it? This is also the reason why the model of enjoying yuan appears.你却把她当妹子，呵护她殷切周到的很。清末年间，一代侠女燕阳春，少年惨遭灭门，独自一人背负报仇和传承双重重任，于天津卫和石家庄闯江湖。她行侠仗义。她先后与赵飞云、卫东然、张占林三个截然不同的男人发生不同的情感纠结，暗恨交织，情义两难，可歌可泣。而她抚养的五个孩子——燕赵、燕阵、燕军、燕红、张山，都在乱世之中做出不凡之举，经历惊心动魄。同时，燕阳春与她的两大仇敌马彪和樊月斗智斗勇。助父灭洋，孤身报仇，杀富济贫。燕阳春从清末走到民国，从民国走到抗战，从抗战走到解放战争，再到新中国，经历了中华民族的深重苦难，伟大蜕变，从一代侠女蜕变为乱世英雄，最后成为一个伟大的母亲。If an attacker sends SYN packets quickly with their own undisguised IP address, this is a so-called direct attack. This attack is very easy to implement because it does not involve spoofing or modifying packets below the user layer of the attacker's operating system. For example, he can simply send many TCP connection requests to implement this attack. However, for this attack to work, the attacker must also prevent his system from responding to SYN-ACK packets because of any ACK, RST, or ICMP (Internet? Control? Message? Protocol) will cause the server to skip the SYN-RECEIVED state (go to the next state) and remove the TCB (because the connection has been successfully established or recycled). Attackers can do this by setting firewall rules, causing the firewall to block all packets (except SYN) to reach the server, or causing the firewall to block all incoming packets so that SYN-ACK packets are discarded before reaching the local TCP handler.The following is the most popular black-and-white ordinary version comparison. It is clear at a glance that the gold label is not fake for the time being, but it is really not good-looking. Conditional recommendation of real goods is really much better than NIKE elite, and NIKE Jordan Adidas UA anta lining can be matched, which perfectly solves my brand adaptation disease. A dozen doubles socks at home, Stance did not wear NIKE when he came.
