How To Use JavaScript In HTML

In this article we will show you the solution of how to use JavaScript in HTML, JavaScript, usually known as JavaScript, is indeed a programming language in use for creating websites.

JavaScript is utilized to create online apps and to make websites interactive, making it one of the fundamental web technologies along with HTML and CSS.

Common display standards-compliant modern web browsers qualify through built-in engines without the use of external plugins.

Working with web-related files necessitates loading and executing JavaScript concurrently with HTML markup.

Either directly inside of a Html file or via a separate file which the browser downloads along with the HTML document, this can be done.

By using the special HTML tag <script> that encloses JavaScript code, JavaScript code can be added to an HTML document.

Depending on the time you desire the JavaScript should load, the <script> tag could be added to either the <head> or <body> sections of your HTML.

In general, JavaScript code can be placed inside the <head> section of your HTML document to keep it confined and separate from the body of the document.

However, you should place your script where it's supposed to be called, which is typically within the <body> section, if it must execute at a specific location within the layout of a page, like if you're using document.write for generating content. We'll add a <script> element and some JavaScript code to the HTML file in order to accomplish this.

Step By Step Guide On How To Use JavaScript In HTML :-

<!DOCTYPE html>
      <title>JavaScript Internal Script</title>
      <base href = "" />
      <script type = "text/JavaScript">
         function Hello() {
            alert("Hello, World");
      <input type = "button" onclick = "Hello();" name = "ok" value = "Click Me" />
  1. 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.
  2. Next comes the body tag, which defines the body of the webpage. You can create this same content for your site in one specific location.
  3. After that, a <script> tag can be used to include us on an HTML page. Following the title tag in the <head> tag, the script tag must be entered between the opening and closing brackets. Then enter the JavaScript function.
  4. Under script we create an alert object as hello world.
  5. Then we close the script and head.
  6. Then we open the body and create button for clicking object.

Conclusion :-

JavaScript, sometimes referred to as JS, is a type of client-side scripting languages that is frequently used during web development to generate contemporary and dynamic web sites.

Scripting languages are those that are not freestanding in nature, and in this context, the term "script" refers to JavaScript, which runs on the client system.

In other terms, you can say that languages that need the support of some other language to be executed are referred to as scripting.

For instance, JavaScript programmes require HTML to run and cannot be embedded into HTML code.

I hope this article on how to use JavaScript in HTML helps you and the steps and method mentioned above are easy to follow and implement.
