What Is The Best Way To Get An Elements Tag Name In Js

When working with JavaScript, there are often times when you need to access specific attributes of an element on a webpage. One common task is to retrieve the tag name of an element, whether it's a div, span, or any other HTML tag. In JavaScript, you can easily achieve this by using the tagName property.

The tagName property is a simple and straightforward way to get the tag name of an HTML element in JavaScript. It allows you to access the tag name of an element without complicated code or unnecessary steps. This property returns the tag name of the specified element in uppercase.

To use the tagName property, you first need to select the element you want to get the tag name of. This could be done using various methods like getElementById, getElementsByClassName, querySelector, or any other DOM selection method based on your requirements. Once you have the element selected, accessing its tag name is a breeze.

Here's a quick example to demonstrate how you can get the tag name of an element in JavaScript:

<title>Get Element Tag Name Example</title>


    <div id="myDiv">Hello, World!</div>

    
        const element = document.getElementById('myDiv');
        const tagName = element.tagName;

        console.log('Tag Name:', tagName);

In the example above, we have a simple HTML document with a div element that has an id of "myDiv." We then use the getElementById method to select this div element and store it in the "element" variable. Next, we access the tagName property of the element, which gives us the tag name of the element, in this case, "DIV." Finally, we log the tag name to the console for demonstration purposes.

It's important to note that the tag name returned by the tagName property will always be in uppercase, regardless of how it's written in the HTML document. This ensures consistency and makes it easier to work with the tag name in your JavaScript code.

By using the tagName property in JavaScript, you can quickly and efficiently retrieve the tag name of any element on your webpage. Whether you need this information for debugging, styling, or dynamic content generation, knowing how to get an element's tag name in JavaScript is a valuable skill for any web developer.
