The src attribute of the script tag is used to add or include external JavaScript files into any number of HTML files. It increases the code reusability.
Syntax:
<script type="text/javascript" src="external.js"></script>
<script type="text/javascript" src="external.js"></script>
<script type="text/javascript" src="external.js"></script>
First, create a JavaScript file and then save the file with the .js extension. After that, we can use the src attribute of the script tag to use this already-created file.
test.js
function show() {
alert("External JavaScript file.");
}
function show() {
alert("External JavaScript file.");
}
function show() {
alert("External JavaScript file.");
}
