Introduction to jquery selector and jquery Selector

Introduction to jquery selector and jquery Selector

First, let's talk about the advantages of the jquery selector:

1. Simple Writing 2. Support for css1.0 to 3.0 selector 3. Complete processing mechanism.

Let's talk about classification:

Jquery selectors include basic selectors, hierarchical selectors, attribute selectors, basic filter selectors, and visibility filter selectors.

 

The basic selectors include: Tag selector, class selector, ID selector, Union selector, intersection selector, and global selector.

There are two common options: class selector and ID selector.

The class selector can directly write the specified tag name. For example, $ ("h2" ).css ("background", "red") sets all h2 elements to red.

The ID selector matches elements based on the given ID. For example, $ (". title" ).css ("background", "green") indicates that the element whose id is set to title is green.

 

Hierarchical selectors include child selector, child selector, adjacent element selector, and peer element selector.

There are two common types: descendant selector and child selector.

The descendant selector is the element of an element descendant. For example, h1 em {color: red;} indicates that the em element in h1 is set to red.

A word selector is a child element of an element. For example, h1> strong {color: blue;} indicates that the strong element in h1 is set to blue.

 

The rest will not be detailed. If you want to know more, you can check the information.
