How to decode a string after encoding in JavaScript?

JavascriptObject Oriented ProgrammingFront End Technology

To encode a string we need encodeURIComponent() or encodeURI() and to decode a string we need decodeURIComponent() or decodeURI(). Initially, we have used escape() to encode a string but since it is deprecated we are now using encodeURI().

syntax-1

encodeURIComponent(string);

syntax-2

decodeURIComponent(string);

Example

In the following example, initially, a string is taken and encoded using encodeURI() and later decoded using decodeURI(). Later on both the encoded and decoded results were displayed in the output.

<body>
<p id = "encoding"></p>

   var str = "Tutorix is the best e-learning platform";
   var enc = encodeURI(str);
   var dec = decodeURI(enc);
   var res = "After encoding: " + enc + "
   </br>" + "After Decoding: " + dec;
   document.getElementById("encoding").innerHTML = res;
</script>
</body>
</html>

Output

After encoding: Tutorix%20is%20the%20best%20e-learning%20platform
