In this issue, the editor will bring you about how to understand the JSON performance of server-side classes. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

To demonstrate JSON performance, let's look at a person object with a list of vehicle objects and a person object that can own one or more vehicles. Each vehicle has the following attributes: brand registration code CC browser UI brand name brand name must not contain numbers. A brand name can contain up to two words, with a space in the middle. Registration code must be all digits.

It must be all numeric, with a minimum value of 50 and a value of 5000, and there will be three input fields corresponding to the vehicle attribute in which the user can enter information. Next, you'll see how to group authentication messages into JSON groups and how to access them.

Traditional methods

Now, when the vehicle data entered by the user is 40CC, the program must display a message indicating that the entered data is not within a valid CC range. You can simply display this message with the code in listing 1.

If (cc

) {alert ();}

JSON performance is a server-side class that contains international messages about vehicles (such as vehicleCCRangeMsg). This approach is a bit confusing: in this approach, you add server-side code to all client-side validation functions to check conditions and display messages. If you change the way metadata and messages, such as server-side classes or variables, are organized, you will have a headache of changing the client script validation functions that use these metadata and messages.

The above is the editor for you to share how to understand the server-side class JSON performance, if you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
