Unescape HTML entities in JavaScript?



To unescape HTML entities in JavaScript, use the unescaped() function. Let’s say you want to encode special character with the unescape() function −

document.write(unescape("Demo%20Text%20")); 

In this article, we will see two examples −

  • Unescape Entities
  • Decode the Encoded String

Unescape Entities

Example

Lo unescape, we will use the unescaped() method in JavaScript. Let us see an example −

<!DOCTYPE html> <html> <body> <h2>Demo Heading</h2> <script> document.write(unescape("Demo%20Text%20")); </script> </body> </html>

Output

Decode the Encoded String

Use escape() for encoding and unescape() for decoding. Here, we will set a sample string under the escape() method to encode −

var myStr = escape("Demo Text!!!");
document.write("Encoded String = " + myStr); 

After that, we will use the unescape() to decode the encoded string −

document.write("Decoded = " + unescape(myStr)) 

Example

Let us now see the example −

<!DOCTYPE html> <html> <body> <h2>Demo Heading</h2> <script> var myStr = escape("Demo Text!!!"); document.write("Encoded String = " + myStr); document.write("<br>"); document.write("<hr>"); document.write("Decoded = " + unescape(myStr)) </script> </body> </html>
