在办公室的椅子上剧烈运动

In the above code, we use three functions, order500, order200, orderNormal to handle its own business logic, If the current own function cannot handle things, We pass it to the following function to handle it. By analogy, Until there is a function that can handle him, Otherwise, the responsibility chain mode will leave the chain directly, telling that it cannot be processed and throwing an error prompt. Although the above code can be used as the responsibility chain mode, we can see from the above code that the Order500 function depends on functions such as Order200, so there must be this function, which also violates the open-closed principle in object-oriented. Let's continue to understand writing flexible and detachable responsibility chain nodes.世代相传的诅咒，他注定孤独一生，可却偏偏遇上了苏流安那个闯进人心的妖孽，开始了漫长追妻路。“主上，有人要推主母下水！”不急，扔井里泡六个时辰去。“主上，有人公然对主母不敬！”“不急，到最热闹的街上给剁碎了去。”“主上，主母又溜了。”“不急……等等，哪个方向？！”他是权倾朝野的缪王、富可敌国的商家家主，他一人之下，呼风唤雨，只手遮天，却在追妻路上掉了节操。　　这是一部讲述如天秤般摇摆的一位少女命运的故事。杜殇这才放下心来，抢到李斯身前，说道：主人，大王是不在了，还有子夜公主啊，他是您的外孙女，你唯一的亲人啊。接范依兰入王宫除了那某些心照不宣的意思之外。改编自曾经创作了《功名十字路》的大石静的同名小说，将目光瞄准了40岁的魅力女人们。围绕着有过婚姻经历成熟的万人迷诗文（永作博美）、平凡的家庭主妇满希子（寺岛忍）、红杏出墙的主妇美波（羽田美智子）以及工作狂乃里（高岛礼子）四个老同学展开。In web development, Picture preloading is a common technique, If you set the src attribute directly to the img tag node, If the picture is larger, Or if the network speed is relatively slow, Before the picture is loaded, The picture will be a blank scene for a period of time. This is not good for the user experience, so at this time we can use a loading loading picture as a placeholder to prompt the user that the picture is being loaded before the picture is loaded. After the picture is loaded, we can directly assign a value to the picture. The following code is as follows when we do not use proxy mode to preload pictures:
