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.
<html>
<body>
<p id = "encoding"></p>
<script>
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 After Decoding: Tutorix is the best e-learning platform
