Compared with the example of electric lights, file uploading differs in that it will now face more complicated conditional switching relationships. In the example of an electric lamp, the state of the electric lamp is always from off to on and then to off, or from off to low light, low light to strong light, strong light to off. ABCA always seems to follow the rules, so even if you don't use the state mode to write the light program, but use the original if, else to control the state switching, you won't lose yourself in logic writing, because the state switching always follows some simple rules.
"State Pattern Reconstruction"
However, for large-scale project development or framework design, it is obviously better to organize code with design patterns.
For example, I now need to create a div element on the page. Then we definitely need a function to create the div, Now all I need is this function, which is only responsible for creating div elements. It doesn't want to take care of the rest, That is, to realize the principle of single responsibility, Just like Kissy on Taobao, At the beginning, they defined Kissy to do only one thing and did it well. The specific instantiation class in the monomer mode was handled by the agent function. The advantage of doing so was that the specific business logic was separated. The agent only cared about the business logic of the agent. Here, the function of the agent was to instantiate the object and instantiate it only once. Create div code just create div, the others don't care; The following code:
虎子睁大眼睛叫道：这不是……不是那个……他没说下去，却望向香荽。
The fifth step is to write the implementation of each state class. It is worth noting that StateFactory is used to avoid the problems caused by the absence of abstract classes in javascript.

CDMA is the English abbreviation of Code Division Multiple Access (CodeDivisionMultipleAccess). It is a brand-new and mature wireless communication technology developed on spread spectrum communication technology, a branch of digital technology. The principle of CDMA technology is based on spread spectrum technology, that is, the information data with a certain signal bandwidth to be transmitted is modulated by a high-speed pseudo-random code with a bandwidth much larger than the signal bandwidth, so that the bandwidth of the original data signal is expanded, then modulated by the carrier wave and sent out.
