This article will explain in detail what json means for everyone. Xiaobian thinks it is quite practical, so share it with everyone for reference. I hope you can gain something after reading this article.

What is JSON?

JSON(JavaScript Object Notation) is a lightweight format for data exchange that is easy to read and write, as well as easy to machine parse and generate.

The structure of JSON is based on two things:

1. A collection of "name/value" pairs. In different languages, it is understood as an object, record, struct, dictionary, hash table, keyed list, etc.

2. An ordered list of values understood in most languages as an array.

JSON uses:

JSON represents JavaScript objects in a specific string form. If you assign a string of such a form to any JavaScript variable, then the variable becomes an object reference, and the object is constructed from the string, which seems a bit awkward, but we will use an example to illustrate.

Suppose we need to create a User object with the following attributes

user ID

user name

User Email

You can use the following JSON form to represent a User object:

{"UserID":11, "Name":"Truly", "Email":"zhuleipro◎hotmail.com"};

Then if you assign this string to a JavaScript variable, you can use any of the object's attributes directly.

Full Code:

var User = {"UserID":11, "Name":"Truly", "Email":"zhuleipro◎hotmail.com"}; alert(User.Name); About "what does json mean" this article is shared here, I hope the above content can be of some help to everyone, so that you can learn more knowledge, if you think the article is good, please share it for more people to see.
