These are the two predefined functions or global functions in JavaScript, which are used to encode and decode a URI. encodeURI() is used to encode the URI and decodeURI() is used to decode the URI.

Example:

<html>
<head>
<title>JavaScipt Example</title>
</head>

<body>
	<script>
		var uri ="test page.aspx?val=Hello world!!";
		var enc_str = encodeURI(uri);
		var dec_str = decodeURI(uri);
		
		//printing the values
		document.write("Actual URI: " + uri);
		document.write("<br>");
		
		document.write("Encoded URI: " + enc_str);
		document.write("<br>");
		
		document.write("Decoded URI: " + dec_str);
		document.write("<br>");				
	</script>
</body>
</html>

Output

Actual URI: test page.aspx?val=Hello world!!
Encoded URI: test%20page.aspx?val=Hello%20world!!
Decoded URI: test page.aspx?val=Hello world!!
