Javascript Beginner Part-1

January 4, 2020 comments off

Hi, I am going to introduce some examples on adding javascript with HTML pages. you can add javascript with the help of <script></script> tag within head or body section.

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Initializing Variable</title>
</head>
<body>
<script>
// Varibale define and initiliazation
var price = 101;
document.write("Price :" +price);
//second statement
var product = "Apple";
document.write("<br>Product Name: " + product);
</script>
</body>
</html>

Now, I am going to discuss an external way of adding javascript to our web pages. you have to create one sample.js file and add the link in the main page under the <head></head> area.

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>External Javascript</title>
<script src="sample.js" type="text/javascript"></script>
</head>
<body>
<h1>Adding Javascript by External Link</h1>
</body>
</html>

Let’s see an example of write function. this function is used to show the data on a webpage. for this you have to see an example below:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>write Function in Javascript</title>
<script>
document.write(4+2);
</script>
</head>
<body>
<h1>Using write function</h1>
</body>
</html>
