While transferring the data over the network or sometimes while saving data to the database, we need to encode the data. The function escape() is a predefined function in JavaScript, which encodes the given string.

It encodes almost all special characters including spaces.

Note: escape() function does not encode some of the special characters like @+-/.*_

Example:

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

<body>
	<script>
		str = "Hello world!";
		//Actual string
		document.write("Actual string is: " + str);
		document.write("<br>");
		//encoded string
		document.write("Encoded string is: " + escape(str));
		document.write("<br>");

		//assign another string
		str = "email id: [email protected]";
		//Actual string
		document.write("Actual string is: " + str);
		document.write("<br>");
		//encoded string
		document.write("Encoded string is: " + escape(str));		
	</script>
</body>
</html>

Output

Actual string is: Hello world!
Encoded string is: Hello%20world%21
Actual string is: email id: [email protected]
Encoded string is: email%20id%3A%[email protected]
