DOM enables dynamic access and updating of web content, while BOM provides APIs for interacting with browser windows, including controlling browser behavior and obtaining information about the browser and user environment. DOM is mainly used It is used to operate web page content, while BOM is mainly used to operate browser windows and interact with browsers. Together, they form an important foundation in Web front-end development and provide developers with rich methods to control and operate web pages and browsers. , realize web applications with strong interactivity and good user experience.

DOM (Document Object Model) realizes dynamic access and update of web page content. It represents HTML, XML and other documents as a tree structure. Through the API provided by DOM, developers can easily access, modify, add or delete elements, attributes and content in the document. The main function of DOM is to enable developers to use scripting languages (such as JavaScript) to dynamically change the content, structure and style of the page, thereby achieving rich interactive effects.
BOM (Browser Object Model) provides an API for interacting with the browser window, including controlling the behavior of the browser, obtaining information about the browser and the user environment, etc. BOM does not belong to the W3C standard. Its implementation varies from browser to browser, but it provides developers with some capabilities to interact with the browser, such as controlling the size and position of the browser, managing browsing history, and popping up dialog boxes. and other functions.
Therefore, DOM is mainly used to operate web page content, while BOM is mainly used to operate browser windows and interact with browsers. The two together form an important foundation in Web front-end development, providing developers with rich methods to control and operate web pages and browsers, and realize Web applications with strong interactivity and good user experience.
