- 3. Decode HTML code with jQuery
In one of the project, we are storing all form fields in json string format (i.e. {"name":"myname", "email":"may@xyz.com", "address":"myaddressdetail"}) in the database table.

At here I want to convert the HTML-escaped equivalents code to appropriate special character (i.e. & needs to be converted into & sign).
