What is the definition of behavior in javascript
Behavior is a combination of events and actions. In Dreamweaver, a behavior is actually a piece of JavaScript code inserted into a web page. These codes can be used to achieve some dynamic effects, allowing the viewer to interact with the web page, so that the web page can respond intelligently based on the viewer's operations. Let's distinguish the inner relationship between the four concepts of object, event, action and behavior.
Object: It is the subject that generates behavior. Most web page elements can become objects, such as pictures, text, multimedia, etc., or even the entire page.
Event: It is the reason for triggering an action. It can be attached to various page elements or to HTML tags. An event is always targeted at page elements or tags, for example, moving the mouse onto the picture, moving the mouse out of the picture, clicking the left mouse button on a page element, etc. Different types of browsers support different types and numbers of events. Generally, higher version browsers support more events.
Action: Use actions to complete dynamic effects, such as exchanging images, popping up information, opening a browser, playing sounds, etc. are all actions. An action is usually a piece of JavaScript. There are many system behaviors built into Dreamweaver. Using these codes will automatically add JavaScript code to the page, saving users the trouble of writing code.
Behavior: The combination of events and actions constitutes behavior. For example, associate the onClick event with a piece of JavaScript code that is executed when an object is clicked. An event can be associated with multiple actions, that is, multiple actions can be performed when an event is triggered. In order to achieve the desired effect, users can also specify and modify the order in which actions occur.
