You can try to run the following code to decode a URL component −
<!DOCTYPE html>
<html>
<body>
<button onclick="display()">Check</button>
<p id="demo"></p>
<script>
function display() {
var uri = "http://example.com/welcome msg.jsp?name=åmit&sub=programming";
// first encode
var encode = encodeURIComponent(uri);
var decode = decodeURIComponent(encode);
var result = "Encode= " + encode + "<br>" + "Decode= " + decode;
document.getElementById("demo").innerHTML = result;
}
</script>
