In this article we will show you the solution of how to add JavaScript file in HTML, the block in JavaScript code that may be "called" upon to perform a specific task is known as a function.
A function might be used, for instance, to handle events like a button click by the user.
An HTML document can contain any number of scripts. An HTML page can have scripts in either the body or the head section, or both.
JavaScript, sometimes referred to as JS,is one of the client-side scripting languages that is frequently used during web development to generate contemporary and dynamic web sites.
The term "script" in this case refers to JavaScript, a non-standalone language that executes on the client system.
In other terms, we can argue that scripting refers to languages whose execution depends on the assistance of another language.
For instance, JavaScript programmes require HTML to run and cannot be embedded into HTML code.
JavaScript is used on websites in a variety of ways, including to create picture galleries, manipulate the DOM, validate forms, and more.
Many programming languages are used to create web pages, with HTML and JavaScript being two of them.
The Hypertext Mark-up Language, or HTML, abbreviation is used to build the structure of the web pages you see every day online.
Javascript, meantime, is a well-known programming language used to add dynamic functionality to web pages to enhance their appeal.
You must include the JavaScript file in your HTML content for these languages to function together.HTML can be used to show static material, such a collection of photographs, for example.
Unfortunately, static pages are gradually disappearing from the web. The majority of content available nowadays is interactive and features eye-catching slide shows,forms, and menus.
They improve user experience and make the page more dynamic.
Step By Step Guide On How To Add JavaScript File In HTML :-
<html>
<head>
<script>
function myFunction() {
document.getElementById("demo").innerHTML = "Paragraph changed.";
}
</script>
</head>
<body>
<h2>Demo JavaScript in Head</h2>
<p id="demo">A Paragraph</p>
<button type="button" onclick="myFunction()">Try it</button>
</body>
</html>
- The browser is informed of the HTML version we are using in our first line, which is <HTML>. Tags are the foundation of HTML documents.
- The HTML <script>.....</script> tag can be used to enclose JavaScript code inside an HTML programme so that it can be included to HTML pages.
- Because it all depends just on the structure of a web page which the users use, users also can define JavaScript code inside the <body> tags (we may also say body section) and <head> tag.
- Then we create a paragraph.
- Then we create a button for the clicking function.
- Finally, after closing all tags, </body></html> but also code should be executed.
Conclusion: -
Scripting languages are used to accomplish this, with JavaScript being one of the most well-known.
It enables web designers to create interactive websites that engage users and vice versa.
Although there are other other languages, none of them are as well-known as JavaScript.
It works best when combined with HTML to realize its full potential.
