What is DOM? – Application and how to manage livestock in JavaScript

If you have just started learning JavaScript, you may have heard the DOM name, but don’t know exactly what. In this article we explain what DOM is and what it is useful. We also look at a few examples of JavaScript code and look at how the elements are selected from an HTML document, how to create elements, how to change in -line CSS styles, and how to respond to events.

DOM stands for Document Object Model means an object -oriented model. This standard is defined by the World Web Consortium (W3C). In fact, DOM is a programming interface or API that allows us to create, modify or remove elements from HTML, XML and XHTML documents. We can also add events to these elements through DOM to make our web page more dynamic.

This article is a brief introduction to some useful DOM methods, but there are many more examples related to the DOM standard and its methods that we have not covered in this article. So if you want to start building JavaScript beginner projects and working with DOM, we suggest you find sample JavaScript beginner projects from internet sources and start practicing and coding.

The points we reviewed in this article are summarized as follows:

• DOM stands for Document Object Model and is a programming interface that allows us to create, modify or delete elements from an HTML document. We can also add events to these elements to make our web page more dynamic.
• In JavaScript, you can select elements using methods such as getElementById(), querySelector and querySelectorAll().
• If you want to add new elements to your html document, you can use the document.createElement() method.
• You can change the inline CSS styles of elements using the style attribute.
• If you want to add events to elements such as buttons, you can use the addEventListener() method.
