jQuery Syntax

This lesson is part of jQuery · All levels

Summary

jQuery syntax always follows the $(selector) pattern: a function that contains a selector to select elements, followed by the method that implements the action. The dollar sign is a jQuery function, whereas the selector can be a tag name, a class, an id, or an attribute. Almost all jobs in jQuery follow this simple pattern, so once you understand the pattern you can be quick to master.
