I have a .js file defined as follows:
<script>
function sayHello() {
alert("Hello World");
}
</script>
And I have a .html file defined as follows:
<!doctype html>
<html>
<head>
<link rel="stylesheet" href="css/testCSS.css">
<title>test html</title>
</head>
<body>
<script type="text/javascript" src="js/testJS.js"></script>
</body>
</html>
How can I call the sayHello() function?
script.js
function sayHello() {
alert("Hello World");
}
index.html
<!doctype html>
<html>
<head>
<title></title>
</head>
<body>
<script src="script.js"></script>
<script>
sayHello();
</script>
</body>
</html>
You just need to call it!
let me explain in an example. let's say you have a button in that html that calls sayHello function.
<button type="button" onclick="sayHello ()">Say hello</button>
I think you should take a look at here.
Jus replace the link to script with content of .Js file...
Or call the function
<script>
sayHello()
</script>
