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:(1) Two vertical mast lights to replace the lights specified in Article 23, paragraph 1 (1) or paragraph 1 (2). When the towing length from the stern of the tugboat to the rear end of the towed object exceeds 200m, three such lights are vertically displayed;"This story tells us that we should be industrious, brave, intelligent and witty, and we can live a happy life."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.A prototype object is given. Q: How can this be done? A: It's very simple. Just give a prototype class directly.Precautions?
