HTML Function

 

HTML (Hypertext Markup Language) is the standard markup language for creating web pages and web applications. It allows developers to define the structure and presentation of content on the web.

 

In HTML

functions can be used to perform specific tasks and manipulate elements on a web page. These functions are written using JavaScript

a programming language that can be embedded into HTML code.

 

Here are some common HTML functions:

 

getElementById

This function is used to retrieve an HTML element with a specified id.

document.getElementById("elementId");

 

getElementsByTagName

This function is used to retrieve all HTML elements with a specified tag name.

document.getElementsByTagName("tagName");

 

getElementsByClassName

This function is used to retrieve all HTML elements with a specified class name.

document.getElementsByClassName("className");

 

createElement

This function is used to create an HTML element with a specified tag name.

document.createElement("tagName");

 

appendChild

This function is used to add an HTML element as a child to another element.

parentElement.appendChild(childElement);

 

removeChild

This function is used to remove an HTML element from its parent element.

parentElement.removeChild(childElement);

 

setAttribute

This function is used to set the value of an attribute for an HTML element.

innerHTML

These are just a few examples of the many HTML functions available to developers. Using functions

developers can create dynamic and interactive web pages that respond to user actions.
