Adding JavaScript to Your Web Page
There are two ways of adding JavaScript to your web page. They are
- External JavaScript
- Inline (Internal) JavaScript
External JavaScript
The HTML <script> tag with src attribute is used to link JavaScript to a webpage.
Note: The external JavaScript file used in this example is alert-me.js
Example
HTML Online Editor
<!DOCTYPE html>
<html lang="en-US">
<body>
<button onclick="myFunction()">Click Me</button>
<script src="/script/alert-me.js"></script>
</body>
</html>
Inline JavaScript
The HTML <script> tag is used to add inline JavaScript to a webpage.
Example
HTML Online Editor
<!DOCTYPE html>
<html lang="en-US">
<body>
<button onclick="myFunction()">Click Me</button>
<script>
// Inline JavaScript goes here.
function myFunction(){
alert("I'm from Inline JavaScript");
}
</script>
</body>
</html>
