Modifying Elements in the DOM

Once you have selected an element from the DOM, you can easily modify its content and attributes using JavaScript. This enables you to update the text, add or remove classes, change the attributes, or even add new elements.

To modify the content of an element, you can use the textContent property. This property allows you to set or retrieve the textual content of an element. For example, let's say we have an element with the id myElement:

1<div id="myElement">Original Content</div>

We can change the content of this element using JavaScript:

1const element = document.getElementById('myElement');
2element.textContent = 'Hello, AlgoDaily!';

This code will update the text content of the element to 'Hello, AlgoDaily!'.

Similarly, you can modify the attributes of an element using the appropriate property such as innerHTML, value, or setAttribute(). You can also create new elements and append them to the DOM using methods like createElement() and appendChild().

Remember to take advantage of the programming concepts and technologies you are already familiar with, such as Java, Spring Boot, and MySQL, to better understand and relate to the concepts of JavaScript and DOM manipulation.

Keep practicing and experimenting with different modifications to build familiarity and confidence in working with the DOM!
