How To Use Html In Javascript

by

When building a dynamic web application, it’s often necessary to manipulate HTML elements using JavaScript. In this blog post, we will discuss the different ways to use HTML in JavaScript, including creating, modifying, and deleting elements. Let’s dive in!

Creating HTML Elements

To create an HTML element using JavaScript, you can use the createElement method. This method creates an element with the specified tag name, and you can then add attributes, content, and even other elements to it. Here’s an example:

  const newDiv = document.createElement('div');
  newDiv.innerText = 'Hello, World!';
  document.body.appendChild(newDiv);

In this example, we created a new <div> element, set its text content to “Hello, World!”, and then appended it to the document’s <body> element.

Modifying HTML Elements

There are several ways to modify the content and attributes of HTML elements using JavaScript. Let’s take a look at a few examples:

Changing Content

To change the text content of an element, you can use the innerText property. For example:

  const myElement = document.getElementById('example');
  myElement.innerText = 'New text content';

To change the HTML content of an element, you can use the innerHTML property. This allows you to insert new HTML elements as well:

  const myElement = document.getElementById('example');
  myElement.innerHTML = 'New <strong>HTML</strong> content';

Changing Attributes

You can use the setAttribute method to modify an element’s attributes (or create new attributes if they don’t exist). Here’s an example of changing the class of an element:

  const myElement = document.getElementById('example');
  myElement.setAttribute('class', 'new-class');

Deleting HTML Elements

To remove an HTML element from a webpage, you can use the remove method or the removeChild method. Here’s an example of each:

Using the remove method

  const myElement = document.getElementById('example');
  myElement.remove();

Using the removeChild method

  const myElement = document.getElementById('example');
  const parentElement = myElement.parentElement;
  parentElement.removeChild(myElement);

These examples both remove the element with the ID “example” from the document.

Conclusion

Using HTML in JavaScript allows you to create dynamic and interactive web applications. By manipulating elements, you can change the content and appearance of your webpages on-the-fly in response to user actions or other events. Practice these techniques to become proficient at working with HTML in JavaScript!
