Let’s talk about what jquery.prototype is

jquery.prototype is a property in jquery. It is an object used to contain the public properties and methods of jquery objects.

As the most popular js library, jquery is best known for its convenience and efficiency in DOM operations. jquery.prototype is one of the core components of jquery and plays a very important role in some common jquery operations.

In jquery, each jquery object is generated by passing one or more DOM elements (or CSS selectors, HTML strings) to the constructor. jquery.prototype is an instantiation object of the jquery constructor, which means it is the shared parent element of all jquery objects.

According to the jquery official document, the jquery.prototype object contains a total of 425 methods, which include methods for performing various operations on page elements, methods for processing standard events, and encapsulating ajax requests. methods etc.

For example, in jquery we use the click() method to bind a click event to an element, and this method is actually a method in jquery.prototype.

In addition, jquery.prototype also provides many properties that are convenient for developers to operate, such as the jquery.fn.jquery property, which is used to obtain the version number of the currently running jquery library; jquery.fn.length Attributes are used to obtain the number of elements in the current jquery object, etc.

It should be noted that although jquery.prototype plays a very important role in jquery, developers usually do not need to directly operate jquery.prototype objects. Instead, we should use jquery.fn (equivalent to jquery.prototype) to extend the properties and methods of jquery objects, and use these extended properties and methods in development.

In general, the role of jquery.prototype is very important. It contains the public properties and methods of the jquery object, and provides jquery developers with a very rich interface for operating elements, processing events, and making ajax requests. However, developers need to be careful not to directly operate the jquery.prototype object, but to extend the properties and methods of the jquery object through jquery.fn.
