JS how to get the DOM and get the browser's wide height?

In JavaScript, it is often necessary to get the document element, which is an abbreviation for the HTML Document Object model, which defines a series of standard objects for HTML and a standard way to access and manipulate HTML documents.

Through the DOM, you can access all the HTML elements, along with the text and attributes they contain. You can modify and delete the content, and you can also create new elements. The HTML DOM is independent of the platform and programming language. It can be used by any programming language such as Java, JavaScript, and VBScript.

Dom is independent of the specific programming language and usually accesses the DOM through JavaScript, but it is not strictly required. You can use any scripting language to access the DOM, thanks to its consistent API.
