Course Introduction："JS Abstract Class and Event Design Pattern Video Tutorial", JavaScript is a literal scripting language, a dynamically typed, weakly typed, prototype-based language with built-in support for types. Its interpreter is called the JavaScript engine, which is part of the browser and is widely used in client-side scripting languages. It was first used on HTML (an application under Standard Universal Markup Language) web pages to add dynamic functions to HTML web pages. .

Course Introduction：What is event bubbling? In-depth analysis of the event bubbling mechanism Event bubbling is an important concept in web development, which defines the way events are delivered on the page. When an event on an element is triggered, the event will be transmitted starting from the innermost element and passed outwards until it is passed to the outermost element. This delivery method is like bubbles bubbling in water, so it is called event bubbling. In this article, we will analyze the event bubbling mechanism in depth. The principle of event bubbling can be understood through a simple example. Suppose we have an H

Course Introduction：What is click event bubbling? In-depth analysis of the event bubbling mechanism requires specific code examples. Event bubbling (Event Bubbling) means that in the DOM tree structure, when an element triggers an event, the event will be passed along the DOM tree from the child elements to the root element. This process is like bubbles bubbling, so it is called event bubbling. Event bubbling is a mechanism of the DOM event model, included in documents such as HTML, XML, and SVG. This mechanism allows event handlers registered on the parent element to receive
