JavaScriptJavaScript can be written by two method
- External javascript
- Internal javascript
1) External javascript
In the external javascript, a javascript file is created externally and save this file with the extension of '.js '.
After creating a javascript file we need to add a javascript path to HTML file using <script src="write full file path address.js") </script> inside the head tag.
For example
<!DOCTYPE html>
<html>
<head>
<title>Teknowize</title>
<script src="E:/javafile.js"> </script>
</head>
<body>
</body>
</html>
2) Internal javascript
In internal javascript, the javascript code may be written inside the head tag or we can also write it inside the body tag.
For example
<!DOCTYPE html>
<html>
<head>
<title>Teknowize</title>
<!-- script written inside head tag -->
<script type = "text/javascript">
<!--
function sayHello() {
alert("Hello World")
}
//-->
</script>
</head>
<body>
<!-- script written inside body tag -->
<script type = "text/javascript">
<!--
document.write("Hello World")
//-->
</script>
<input type = "button" onclick = "sayHello()" value = "Say Hello" />
</body>
</html>
