Exploring DOM Properties in JavaScript

JavaScript provides several properties to access and manipulate the content. Understanding these properties allows you to dynamically update the content of web pages based on user interactions or other conditions.

InnerHTML

The innerHTML property allows you to get or set the HTML content of an element, including tags and text. It is one of the most commonly used properties for dynamically updating page content.

index.html

index.js

The innerHTML retrieves all the content, including HTML tags, and allows for inserting or updating content with HTML tags.

TextContent

The textContent property gets or sets the text content of an element, stripping out any HTML tags. It's ideal when you need to work with plain text without considering the HTML structure.

index.html

index.js

The textContent retrieves text content only, ignoring HTML tags, and sets plain text, automatically escaping any tags.

Value

The value property is used with form elements like <input>, <textarea>, and <select>, allowing you to get or set the value entered by the user.

index.html

index.js

The value retrieves the current value of form elements and sets a new value for input, textarea, or select elements.

Differences Between InnerHTML and TextContent

Practical Example: Updating a User Profile

Imagine a user profile page where initial data is displayed, and the user can update their profile details using a form. When the user submits the form, the content on the page updates dynamically.

index.html

index.css

index.js

Initially, the profile displays a predefined username and bio, which can be modified through input fields. When the "Save Changes" button is clicked, JavaScript updates the displayed profile: textContent updates the username as plain text, while innerHTML updates the bio to allow for basic HTML formatting, reflecting any edits the user makes.
