What is jquery framework?

I believe some friends should have heard of jQuery, but do you understand it? Do you know what he is used for? Next I will talk to you about what the jQuery framework is.

#jQuery is a fast and concise JavaScript framework.

jQuery, as the name implies, is JavaScript and Query. jQuery is free and open source. It can simplify querying DOM objects, handle events, create animations, handle Ajax interaction processes, and is a javascript library that is compatible with multiple browsers. The core concept is write less, do more (write less, do more).

jQuery advantages:

1. Small size and flexible use (just introduce a js file).

2. Conveniently select page elements (imitating CSS selectors to be more precise and flexible).

3. Dynamically change page style/page content (manipulate DOM, dynamically add and remove styles).

4. Control response events (dynamically add response events).

5. Provide basic web page special effects (provide encapsulated web page special effects methods).

6. Quickly implement communication (ajax).

7. Easy to expand and rich in plug-ins.
